EDITOR'S MEMO www.adhesivesmag.com

FALL POTPOURRI

6075 B Glick Rd., Powell, OH 43065 • 281-550-5855

PUBLISHING STAFF Autumn is one of my favorite seasons. Mums of all shapes and sizes are blooming, the leaves are turning the most amazingly vibrant colors, and everyone’s digging out their cold-weather clothes. It seems like every day brings something new and interesting. We’ve put together an exciting fall potpourri of editorial for you in this issue of ASI. For example, David Nick, president and CEO of DPNA International, Inc., explores “The Role of Adhesives and Sealants in the BRICS Alliance.” Despite the worldwide economic downturn, the countries in the alliance—Brazil, Russia, India, China and South Africa—are prospering and offer a number of opportunities for adhesives and sealants manufacturers. Discover the potential possibilities on pp. 16-17. The selection of the proper adhesive(s) for flexible packaging applications is vital. The flexible packaging industry is growing, and adhesives manufacturers can help the sector meet the increasing demand. According to Bonnie Richter, Splicing Business Unit manager for Adhesives Research, Inc., “Adhesive manufacturers can add significant value to products by understanding the specialized needs of this market and guiding flexible packaging manufacturers and converters in their adhesive selection process.” Turn to “Increasing Packaging Speeds” (pp. 20-23) to learn more. We also offer information on testing/quality control in this issue, with articles on rheological tests (“Rheology Solutions,” pp. 30-32) and industry icon John Johnston’s impact on the testing and development of pressure-sensitive adhesives (“Passing the Torch,” pp. 33-36). Be sure to take a look at the issue’s full Table of Contents on p. 5, or simply scan the mobile tag on the cover for direct access to all of our content online.

COMPANY NEWS ASHLAND recently announced it has completed its acquisition of privately owned International Specialty Products Inc. (ISP), a global specialty chemical manufacturer of innovative functional ingredients and technologies. The purchase was an all-cash transaction for $3.2 billion, subject to post-closing adjustments for changes in net working capital and certain other items. ISP will be integrated into the Ashland Aqualon Functional Ingredients commercial unit, more than doubling the size of Ashland’s highest margin business. The combined unit will be called Ashland Specialty Ingredients. For more information, visit www.ashland.com. BASF announced plans to invest in a world-scale production site for acrylic acid, butyl acrylate and superabsorbent polymers (SAP) in Camaçari, Bahia, Brazil. According to the company, this will be the first acrylic acid and superabsorbents plant in South America. With an investment volume of more than @500 million (~ $721 million), it is the largest investment in BASF’s century-long history in South America. In addition, BASF will begin producing 2-ethyl-hexyl acrylate, a raw material for the adhesives and special coatings industries, in its existing chemical complex in Guaratinguetá, São Paulo. This will be the first plant for this product in South America. Visit www.basf. com for additional information.

ANNOUNCEMENT WORLD ADHESIVE CONFERENCE SEEKS PAPERS FEICA, the Association of the European Adhesive and Sealant Industry, has announced a call for papers for the World Adhesive & Sealant Conference (WAC), which will take place Sept. 18-21, 2012, in Paris. The conference is held every four years, alternating between Asia, the Americas and Europe. The upcoming conference’s theme is “Creating the Future.” The objectives are to address key industry challenges, to provide multi-perspective solutions and promote discussion among all the stakeholders, and to strive for both the development and progress of the global adhesives and sealants industry. The conference program is structured into four half-day sessions; each session has four parallel tracks of four speakers (30 minutes each). A total of 64 papers will be presented. The deadline for submitting a paper is Nov. 30. Additional details are available at www.wac2012.org.

ANNOUNCEMENT FLEXCON ADVANCES BIOMIMETIC TECHNOLOGY FLEXcon recently announced that it is successfully supporting biomimetic technologies in partnership with Sharklet Technologies. The collaboration has allowed Sharklet Technologies to create the world’s first technology that inhibits bacterial growth through a chemical-free micro-texture. The surface protection product will be used in environments where bacteria pose a health risk. Sharklet Technologies’ core technology, Sharklet™, is inspired by the microbe-resistant properties of sharkskin and is the first no-kill, non-toxic and environmentally friendly surface designed to inhibit bacterial growth. Sharklet Technologies reportedly selected FLEXcon because the film specialist proved to be the only manufacturer that could successfully image the patented, microscopic texture on film in large production rolls. Sharklet Technologies’ film-based surface protection products can be applied to germ-prone surfaces to reduce the presence of bacteria. These films can be converted into adhesive-backed “skins” for application to high-touch, bacteria-prone areas such as hospital surfaces, public restrooms, childcare facilities, commercial venues, laboratories and animal research facilities. The film may also be manufactured into the top layer of workspace mats to create immediate and moveable surface protection. For more information, visit www.flexcon.com or www.sharklet.com.

FOCUS ON

MAPEI PARTICIPATES IN AEC CARES PROJECT IN NEW ORLEANS APEI helped the community while participating in the American Institute of Architects (AIA) Convention in New Orleans earlier this year. On May 11, the day before the convention began, MAPEI joined a unified AEC Cares team, spearheaded by Reed Construction Data, the AIA Council of Architectural Component Executives (CACE) and Hanley Wood, working to restore parts of the New Orleans, LA, community. AEC Cares is a service project designed to enhance the lives, safety, and security of the parish community and its residents. It also provides the opportunity for industry professionals to meet and engage within meaningful and organized non-business environments. MAPEI contributed mortars and grouts for installing the tile floors in five homes that are being renovated after Hurricane Katrina’s original devastation and subsequent storms. Mike Daniels and Wilbert Adams, MAPEI employees with extensive tile-setting experience, were on hand to volunteer at the work sites. MAPEI also provided caps for all the volunteers on the project. “This outreach project, facilitated by New Orleans Operation Helping Hands, serves as a reminder that, as we go about our daily lives, there is still work to do,” said Steve Ritchie, vice president of Marketing and Business Development for Reed Construction Data. “New Orleans is still in the process of rebuilding a community and culture that have been so profound in shaping this country. We are grateful to the partners, sponsors—Old Castle, Hunter Douglas, PGT, Bluewolf, MAPEI, Naylor and Vinyl Institute—and volunteers

Is the BRICS alliance an opportunity for the adhesives and sealants industry to grow and become a hedge against global economic downward trends? By David P. Nick, President and CEO, DPNA International, Inc. he BRIC acronym (representing Brazil, Russia, India and China) was introduced by J. O’Neill of Goldman Sachs in 2001. The concept was further expanded by Goldman Sachs in its Global Economics Paper No. 99 in 2003. The case was made for a collection of emerging countries that shared certain characteristics such as market size, economic development level, growth rate and population. These countries were described as having a similar and potentially collective atmosphere favorable for sustainable growth and, if a certain level of growth were continued through 2050, the BRICS could represent a global economic powerhouse. The intention was not meant to describe a trading bloc, formal political pact or free trade agreement. Instead, it was presented as four emerging countries that shared a common group of characteristics and together represented a unique economic model. Although the acronym has been referenced by many economists, it did not receive much attention before the deep economic recession of 2008-2010. By the third quarter of 2010, the BRIC economies took on new significance as they had “sailed” through the recession, almost as if it never happened. As predicted, their GDP growth was strong and sustained, thus supporting the concept of the new economic model. Meanwhile, the industrialized, developed economic powerhouse nations suffered deeply. During 2010, South Africa began discussions with the four BRIC countries about joining the alliance. A formal invitation was made by China and agreed by the others. South Africa officially became the fifth member on April 14, 2011, and the acronym was changed to BRICS. This group collectively represents 40% of the world population, 25% of the global land area and nearly 30% of the total GDP. BRICS’ 2010 demographic data is provided in Table 1.

T

BUILDING AN ALLIANCE The BRIC example started out as a selection of four countries with similar characteristics. The countries were simply listed as examples in an exercise that defined groups of countries that exhibit certain economic potentials for growth. The four countries took this grouping seriously. Their representatives eventually met and formed a more formal alliance a few years later, even going so far as to hold regular annual meetings. The group 16

has evolved one step further by establishing trade agreements among themselves. Each country has an agenda, and this alliance solves many issues facing each of them in different ways. Russia gains access to new export markets for its oil and gas, as well as new sources for raw material and agriculture imports. Brazil can export its food products to China and others, and has land available to set up manufacturing bases to get closer to markets in North America. China gains easier access to India markets, has a built-in market for its exports and can import agricultural products. India has well-developed information technology expertise and can readily market its services to the other members while also serving as a manufacturing technology base. Though South Africa doesn’t quite fit the model, it could stand to gain the most. It is a gateway to Africa and has become a model for other African countries. It also has large mineral reserves that are useful to China. Perhaps the most significant factor in this alliance is the opportunity to trade in non-U.S. dollar/euro currencies, a common concern. It is a major issue in their collective purpose to make the alliance work. Each country, when taken individually, faces a variety of challenges to trade with the developed nations of the world. This alliance now provides a large potential market for exclusive trade between the BRICS countries. Each geographic location is strategically aligned (see Figure 1), allowing them to also engage in their own trading pacts and further enhancing their value as an alliance partner. The BRICS countries offer access to otherwise difficult-toreach markets.

INFLUENCING ADHESIVES AND SEALANTS The BRICS country members are in the early stage of expansion in the adhesives and sealants market. A key indicator of the industry size and growth potential is measured as pounds (or kilograms) of adhesive consumption per capita. The market for each of the BRICS countries is shown in the 2010 market data in Table 2. For comparative purposes, per capita consumption in the U.S. is 21.4 lbs (9.7 kg). The BRICS’ total market size, shown in Figure 2, represents 24% (6.3 billion lbs) of the global 2010 adhesives and sealants demand. Excluded are plywood, particle board, MDF binders and carpet backing adhesives. It is estimated that, by 2050, the BRICS’ share of the global market could reach 40%. October 2011

Figure 3 illustrates a possible scenario for demand growth of adhesives and sealants by the BRICS from 2010 to 2050. This represents a conservative approach by keeping the demand within the projected GDP growth levels for 2025 and beyond.

THE FUTURE Since South Africa was invited by China to join as a BRIC country, the other three original members have expressed interest to also invite a candidate of their choosing. A possible list of potential candidates being considered is shown in Table 3. The multi-national members of the adhesives and sealants industry have an opportunity to further establish a presence while the economies are open to investment. When planning market entrance strategies, the BRICS’ growth in established markets October 2011

could be significant. If a formulator or raw material supplier is not already in place, it may be too late in the near future. The BRICS countries are working toward developing a new order of business methodology. BRICS’ market participation can be a good hedge against future market downturns. Interestingly, Goldman Sachs has identified another set of countries, the N-11, that also share sustainability growth factors similar to the BRICS, but in an earlier stage of development (see sidebar). This group may become the next “new order” to supplement the BRICS.

needs of this market and guiding flexible packaging manufacturers and converters in their adhesive selection process.

ADHESIVE SELECTION

Adhesive consultants can evaluate the manufacturing process and the substrates to be spliced in order to specify the right tapes for each application.

he flexible packaging industry is the second-largest packaging segment, representing approximately 18% of the $143 billion U.S. packaging industry. Fueled by steady growth, the industry has benefited from the development of innovative products, advancements in technology, the introduction of flexible packaging into new and existing markets, and the ability to meet the ever-changing needs of customers and consumers. Despite this growth, flexible packaging companies are increasingly feeling the pressure to reduce costs in order to remain competitive. A major driver of price can be seen in the food industry, where consumers are searching for convenience and value in the products they purchase while becoming progressively more interested in their

personal impact on the environment. In response to these demands, the industry is rapidly transitioning from rigid packages to cost-effective film pouches. In addition to lowering material expense, manufacturers and converters are looking to reduce costs by addressing production efficiency as measured in product throughput as it relates to line speeds, downtime, and product waste. Adhesives used for splicing web materials in flexible packaging and converting applications are a necessary component in the equation for efficient throughput; however, selecting the wrong adhesive for a particular machine or substrate can result in costly machine downtime and waste. Adhesive manufacturers can add significant value to products by understanding the specialized

In an industry where time is money, packaging manufacturers and converters need a product that is highly reliable, safe and easy for operators to apply. For many reasons, pressure-sensitive adhesive (PSA) tapes are an attractive bonding choice because they deliver consistent, immediate bonds with minimal preparation, require no adhesive dry times, and eliminate liquid splash to finished product. These features and benefits are proven to reduce downtime and cleanup. A PSA splicing tape used in place of a liquid adhesive allows for uniform thickness of the adhesive during application without the need for application equipment, specialized storage or the use of solvents for thinning. PSA splicing tapes also eliminate OSHA compliance issues regarding the use of liquid adhesives. Multiple factors need to be considered to ensure that the proper adhesive is selected for the application. For this reason, flexible packaging manufacturers and converters can benefit by working directly with an adhesive consultant that is wellversed in splicing tape technology and applications. Consultants can thoroughly evaluate the client’s manufacturing process and the substrates to be spliced, and provide specific training to line operators. October 2011

INCREASING PACKAGING SPEEDS

Splicing tapes for flexible packaging applications are available in a variety of colors, as well as double- and single-faced and transfer adhesive constructions.

Four main factors should be considered when selecting a PSA for a core start or splicing application: substrates to be spliced, oven temperatures, line speeds and web tension. These factors should be evaluated through every step of production—from the beginning processes to final product conversion. Proper consideration ensures that the right splicing product (or combination of products) is used, which helps reduce or eliminate splice failure at any point in the process. A majority of pouch-type designs are comprised of low-surface-energy polyethylene and polypropylene films that require a highly aggressive adhesive available only through rubber-based adhesives, including hot melts. Rubberbased chemistries provide high tack and peel, which is important in automatic flying splices that require adhesion levels to be established in a quarter of a second while having the bond strength to hold and immediately pull the next roll of continuously flowing product. Because rubber-based adhesives can be affected by extended exposure to temperatures over 150°F (66°C), certain chemicals and UV light, it is important to understand the entire manufacturing process to ensure the splice

does not fail in downstream operations that might include these conditions. Additional common packaging substrates include polyester and polystyrene, which are well-suited for acrylic-based adhesives. Acrylics are easily crosslinked to achieve a wide range of performance properties, making them extremely versatile for a number of splicing applications. Although they are high tack, acrylics do not bond as well to low-surface-energy or high-slip substrates. The strengths of acrylics complement the weaknesses of rubber-based chemistries, meaning they perform well in high temperatures (up to 350°F/176°C) and withstand UV light and exposure to solvents. From an efficiency standpoint, most flexible packaging manufacturers using common substrates benefit most by using PSAs for quick-stick application. However, some specialty substrate applications may call for heat-activated or UV-curable adhesive tape technologies as an alternative splicing product.

ADDITIONAL CONSIDERATIONS The competitive and dynamic flexible packaging industry requires adhesive man-

ufacturers to lead proactive interaction with their packaging clientele in order to ensure that the right products are being used for the industry’s ever-changing range of substrates and machinery upgrades. Manufacturers are investing significant capital in replacing or retrofitting production lines for additional automatic capabilities that increase throughput. Millions of dollars are often spent on new machinery, sometimes under the incorrect assumption that the tapes used on the original machinery or in other areas of the plant will successfully perform on new or upgraded equipment. Compatibility is often not the case when line speeds increase to in excess of over 1,500 ft/min. A requalification of the core start and splicing tapes, as well as splice configurations, should occur to maximize performance of any new machinery, or products on new or existing machinery. As packaging materials continue to evolve and flexible packaging manufacturing operations become more automated, adhesive manufacturers will be challenged to offer the right mix of high-performance splicing tapes. While the majority of the PSA splicing choices for flexible packaging

are based on rubber and acrylic formulations, adhesive manufacturers can tailor adhesive chemistry, adhesion levels, coat weights, carrier materials and tape constructions to offer value-added products to address a full range of splicing needs, including adhesives meeting the U.S. Food and Drug Administration’s (FDA) requirements for indirect food contact. As production speeds increase, so does the demand for even more aggressive adhesives for challenging substrates, providing an opportunity for adhesive manufacturers to differentiate their product lines with highly visible and aggressive adhesives for high-slip materials. In this dynamic and fast-paced industry, manufacturers and converters will increasingly rely on adhesive manufacturers to help specify the right products and splice configurations. Charging forward in their mission of increasing speed and efficiency while reducing waste will help manufacturers and converters remain as competitive as possible in today’s marketplace.

With careful research, polymer chemistries can be tailored to end-use applications. By Michelle Moss, Industry Manager, DSM Coating Resins

olymers have been used in the formulation of adhesives for decades. In recent years, the technology base has been optimized and expanded to include a broader range of polymer chemistries. Polymers used for adhesive formulation include water-based acrylic emulsions and solid acrylics, urethane and urethane-acrylic dispersions, and solvent-based polyesters. This later technology is ideal for the lamination of filmic substrates used in flexible packaging. Today, polymers play a major role in the formulation of adhesives for a broad range of applications in other packaging markets such as lidding, labeling, and blister-pack, as well as industrial markets like automotive, general lamination, wood bonding, and consumer markets.

P

BOTTLE LABELING Synthetic polymers are commonly used for paper and polyester labeling substrates. Water-based acrylic copolymers using acid-stabilized colloidal or emulsion technology offer an excellent balance of adhesion and end-performance properties for bottle labeling applications. The main challenge is to balance stable application viscosity (for high-speed filling lines), high-performance adhesive properties and ease of label removal for recycling. NeoCryl BT-207, a water-based acrylic emulsion, is a viable alternative to natural casein products that have been predominantly used in this market. Historically, adhesive formulators have faced major difficulties when replacing natural casein-based adhesives for bottle labeling applications. Manufacturers of synthetic polymers struggled to match the full performance range and benefits of casein. However, due to issues with supply constraints, consistent quality and the price volatility of casein, there is a real need to find a synthetic alternative. The performance of NeoCryl BT-207 closes this gap, offering enhanced performance for high-speed stable viscosity over a pH range of 8-8.6 with improved hyper-condensation resistance for cold-fill bottle labeling. In addition, the emulsion is not susceptible to biological attack. The combination of these benefits provides an advantage in the form of overall cost reduction. 24

FLEXIBLE PACKAGING The significant growth of filmic substrates for flexible packaging is well known; lightweight alternatives to metal cans offer consumers ease of use and allow for more decorative and attractive graphics that are ideal for point-ofsale and marketing promotions. The package itself is constructed of bonded layers of different filmic substrates, including metalized layers and alumina foils, and incorporates closing mechanisms for ease of storage. The ideal adhesive must achieve universal high bond strength with the different material layers, as well as high performance in a variety of packaging procedures, including pasteurizing and retortable processes. Using its capabilities and knowledge of polyester chemistry for can and coil coatings, DSM has developed a polyester polymer for use as a high-performance lamination adhesive. NeoRez P-900, a high-molecular-weight, OH-functional polyester polymer, is recommended for use as a universal laminating adhesive for flexible packaging and filmic substrate applications. This polymer displays excellent adhesion to a broad range of substrates, including co-extruded polypropylene, b i a x i a l - o r i e n t a t e d p o l y p r o p y l e n e a n d p o l y e s t e r, polyethylene, polyamide, and aluminum. NeoRez P-900 can be formulated to take advantage of the high molecular weight to improve productivity with faster lamination throughput, lower post-curing temperature and a more rapid post-curing time. Performance can be enhanced with the addition of an isocyanate crosslinker, which can lead to an overall cost reduction due to the lessened amount of crosslinker required to equal the performance of competitive urethane systems. NeoRez P-900 also features high performance and maintains excellent bond strengths under retorting conditions, which makes it ideal as a flexible packaging lamination adhesive and an alternative to commercial crosslinked, solvent-based urethanes. NeoRez P-900 is free of aromatic isocyanate and amine additives in its composition and is compliant with the U.S. Food and Drug Administration’s food contact requirements. October 2011

DSM Coating Resins uses both pre-polymer and inversion polymerization production techniques to produce a range of urethane dispersions. Careful selection of raw materials and processing conditions yields polymers that are solvent-free, easy to formulate, and feature low activation temperatures and high bond strength (which can be formulated to attain high temperature resistance). NeoRez R-1400 is an aliphatic polyester urethane polymer dispersion developed for heat-activated adhesive formulation. NeoRez R-1400 offers the combined properties of low temperature activation, good early green strength, and high temperature resistance when crosslinked with polydispersible isocyanate. The polymer imparts high bond strengths and displays excellent adhesion to a variety of materials, including wood, common grades of plastic films, and vinyl laminates. The low activation temperature characteristic of the polymer makes this resin ideal for use in waterborne adhesives that require reduced bonding temperatures (i.e., in applications where temperature-sensitive substrates are used, such as decorative vinyl lamination in automotive interiors and kitchen cabinet assemblies).

WOOD ADHESIVES Urea-formaldehyde resins have been used for many years as the workhorse adhesives in wood bonding applications. Inexpensive thermoset urea-formaldehyde is ideally suited to the high performance and long life requirements in applications such as the low-cost, high-volume furniture market and general wood lamination. In today’s market, however, additional focus has been placed on reducing environment impact and maintaining October 2011

worker safety. The use of formaldehyde is therefore under pressure, and the market is looking for viable alternatives. NeoPac E-850 is a formaldehyde-free, water-based aliphatic polyester urethane-acrylic dispersion. This system was developed specifically for use in wood furniture adhesives due to its bond strength and excellent water and heat resistance. As a water-based polymer, it can be highly loaded with mineral fillers to reduce the overall water content in the formulated adhesive without loss of adhesion properties. This is a necessary requirement for most wood laminating production methods in controlling viscosity, wood penetration and faster drying. The product can be used in adhesives to form flat or shaped laminated parts. The nature of the resin imparts the necessary performance to withstand bond stresses in the laminate along bends in the formed components. In addition, it exhibits good water and fatigue resistance properties. The product meets the standards of major flatpack supplier regulations regarding formaldehyde-free and wood furniture construction performance. For more information, visit www.dsm.com.

RHEOLOGY SOLUTIONS for Adhesives Testing When testing adhesive materials, dual capability is vital to the range of necessary rheological tests. By John Walters, Senior Engineering and R/S Product Manager, Brookfield Engineering Laboratories, Inc.

ontrolled stress rheometers with cone/plate or plate/plate geometry are ideally suited for a variety of adhesive measurements. They also have the capability to apply a defined shear rate to the adhesive material. These instruments can operate in either controlled stress mode for yield stress, creep and recovery tests, or at a controlled rate for viscosity testing. The following performance capabilities are important in a versatile controlled stress instrument for running a wide range of rheological tests: • Controlled stress capability, with ramping up to several thousand Pascals • Defined shear rate capability, with ramping up to several thousand reciprocal seconds • Small sample volume on the order of 1-5 mL, depending on spindle geometry • Fast, easy cleanup • Wide temperature range, preferably from 0-200ºC • Fast temperature change, possible when using peltier technology; instruments can change from ambient temperature to 100°C (or

vice versa) in five minutes or less • High torque range up to 50 mNm for measuring thick materials • Spindle geometries with cones and plates of various diameters that allow measurement of viscosities from ~100 cP (100 mPa·s) to >15,000,000 cP (15,000 Pa·s) The following examples describe potential uses of controlled stress rheometers.

VISCOSITY VS. SHEAR RATE FOR TWO ADHESIVES As shown in Figure 1, a simple speed ramp from 0 sec-1 to 100 sec-1 tests two variations of an adhesive. The adhesive indicated by the data shown in red performs well; the green, less so. Tests with a conventional viscometer at one speed produced similar viscosity values. The test with the rheometer over the shear rate range in the figure clearly shows that the green material, while near the red at low shear rates, thins and seems to become unstable at shear rates over 20 sec-1. If the adhesive is applied at fairly high shear rates, the green formulation will not work.

SHEAR STRESS RAMP AND VISCOSITY PROFILE Yield stress (i.e., the point at which flow begins) can be an important property. Many consumer adhesives are supplied in tubes that the consumer squeezes the adhesive out of. If too much force is required to initiate flow, the product may not be acceptable to consumers. Using a controlled stress instrument, a simple stress ramp provides a precise yield stress value. In Figure 2, shear stress is ramped from 0 Pa to ~ 600 Pa over 60 seconds. Because the adhesive does not move until the yield stress is achieved, there is no shear rate (and hence viscosity) until yield takes place. The graph clearly shows that the yield stress value for this adhesive is ~ 50 Pa (see the curve in red), which is an acceptably low value. In addition, this graph shows that the adhesive is pseudoplastic (i.e., exhibits decreasing viscosity with increasing shear rate), so the viscosity will decrease as the consumer squeezes the tube (see the curve in green). The consumer will not need to squeeze the tube with significant force, and the adhesive will be easily applied. October 2011

VISCOSITY VS. SHEAR RATE UP-DOWN TEST TO ASSESS RECOVERY

Figure 1. Viscosity vs. Shear Rate for Two Adhesives

When the adhesive is supplied in a tube or container, force is required for application of the material. Viscosity recovery may be an issue. As force is applied and the shear rate increases, the viscosity will probably change (most commonly, it will decrease). After having been sheared, if the material does not recover to a fairly high viscosity, it may not “stay where it is put,” which can be a problem. A simple two-step flow curve, which only takes two minutes, assesses both the degree of shear thinning behavior and the recovery. The test program has two steps. In the first step, shear rate is ramped from 0 sec -1 to 300 sec -1; in step two, it is ramped from 300 sec -1 to 0 sec -1. As is evident in Figure 3, viscosity in the first step drops dramatically from ~ 80 Pa·s (80,000 cP) at low shear rates to ~ 5 Pa·s (5,000 cP) at 300 sec -1. In the second step, some “interesting” behavior then begins at about 160 sec-1. Although the step-two viscosity values are less than the step-one values for any given shear rate, there is recovery and the final viscosity reading of ~ 52 Pa·s (52,000 cP) will be high enough for the adhesive to stay where it is applied. Figure 2. Shear Stress Ramp (Red) and Viscosity Profile (Green)

TWO-POINT QC TEST While viscosity data taken over multiple rotational speeds provides more information about the fluid flow properties, a quick QC test can be accomplished with two data points: one at high shear rate and the other at a low shear rate. To further simplify the test procedure, this type of test can be done without PC control (though using a printer is recommended). In Figure 4 (p. 32), viscosity readings are taken at 10 sec-1 and 500 sec -1 . The printed output displays viscosity under the term “Eta” and the two values noted are 15.410 Pa·s and 1.279 Pa·s, respectively. This clearly indicates a significant degree of shear thinning behavior, which is desirable for good adhesive performance when in use. Note that all measured values are printed, as well as instrument and program information.

MATH MODEL ANALYSIS OF VISCOSITY DATA USING THE OSTWALD REGRESSION When a controlled stress rheometer is under software control, the ability to apply a regression analysis to the test data offers a significant opportunity to analyze the data quickly and effectively. With good correlation, this allows the estimation of viscosity values at untested shear rates. Figure 5 (p. 32) shows the Ostwald (power law) regression for a nearly Newtonian fluid having a viscosity of ~ 250 Pa·s (250,000 cP). It would take considerably more torque capability in an instrument to test the fluid at a shear rate of 1000 sec -1 (a 30-hp rheometer would be quite expensive). Because the correlation to the Ostwald model is good (99.628, in this case), we can use the model to estimate the viscosity at 500 sec-1 and 1,000 sec-1. The values were 246.725 Pa·s and 246.090 Pa·s, respectively, seen at the end of the results where stress and rate are also shown. The Ostwald n and k values are shown as constants 1 and 0; the n is 0.9962 while the k is 252.489 Pa·s.

materials will pull the vane back toward the start point. In this example, the red, light green and green samples were acceptably stiff; the purple sample was not sufficiently rigid (see Figure 7).

DUAL CAPABILITY VANE SPINDLE ROTATION VS. TIME MEASURES “STIFFNESS” This application uses the vane spindle with a controlled stress rheometer. Vane spindles are useful for low shear measurement of very high-viscosity, near-solid materials. In this case, a heavy flooring adhesive served as the sample. The test includes two steps, using stress (or torque) as the control parameter. In step one, a constant stress or torque is applied. In step two, the stress/torque is removed. This provides a measurement of stiffness by plotting the movement of the vane (in radians) against time. Less stiff materials have more movement. By removing stress/torque in step two, it is possible to get an indication of the degree of elastic behavior; more elastic 32

The examples presented here serve to provide a sense of a controlled stress rheometer’s capabilities. The important point to keep in mind is that this type of instrument operates in both controlled stress and controlled rate modes. When testing adhesive materials, this dual capability is vital to the range of necessary rheological tests. The shift to the use of controlled stress instrumentation is a logical step toward ensuring that R&D and QC labs operate at peak efficiency.

Passing the TORCH Tape industry icon John Johnston looks to the future.

By Joe Mausar, Director of Marketing, Chemsultants International Inc. John Johnston (left) and Dave McCann working with the PMA-1000.

ohn Johnston was born in England in 1925, the same year Richard Drew introduced masking tape to the world. Essentially, Johnston was born in the birth year of industrial tape, and his life would be forever intertwined with the development and testing of pressure-sensitive adhesive (PSA) tape and the tape industry.

J

EARLY EXPERIENCE In early 1950, Johnston unwittingly entered into what would become his lifetime career path when he joined Smith & Nephew as a laboratory technician. In his new job, John did it all—he tested incoming raw materials, performed quality control tests on industrial and medical tapes, and even produced some of Smith & Nephew’s small-volume products (e.g., diachylon bandages). J o h n r e c e i v e d a b a c h e l o r ’s o f science degree in 1958 with majors in chemistry, physics, and pure and applied mathematics. He moved to the U.S. and joined Arno Adhesive Tapes in October 2011

Michigan City, IN, where he began as research chemist. He expanded Arno’s line of adhesive tapes to include a full spectrum of tape types and eventually became vice president of research, development, and technical operations. Johnston later moved to the Johnson & Johnson facility in Chicago, where he was director of technical operations until the company chose to consolidate its operations and closed the Chicago facility. Johnston then joined Tuck Tape in New Rochelle, NY, as the director of research and development. After Tuck was acquired by tesa tape 12 years later, John spent six more years of his career as the director of applications engineering for tesa, supporting R&D, marketing and customers.

PSTC INVOLVEMENT In the early 1960s, John became involved with the fledgling Pressure Sensitive Tape Council. (PSTC was established in 1953.) He has been an active member of PSTC ever since, and has served on its committees as the

council’s technical advisor and consultant for over 15 years. He is currently the technical consultant emeritus for the PSTC. Presented by Johnston in 1973, the very first PSTC technical paper (“Another Look at Peel Adhesion”) set the stage for all future PSTC technical conferences. He chaired the first PSTC conference on hot-melt PSA tape systems in the U.S. in 1975. Johnston served as permanent co-chair for the annual PSTC Technical Conference for 15 years. He presented the first training session on PSA tape technology offered by PSTC at the first world conference on adhesive tapes in 1992. Over the years, John has also presented a number of technical papers for PSTC, including “Hot-Melt Pressure-Sensitive Adhesives,” “Practical Aspects of Formulating and Processing, Tack,” “The History of the Adhesive Tape Industry” and “Alternate Methods of Testing Pressure-Sensitive Adhesive Tapes.” Adhesives & Sealants Industry

industry and has been active with all PSTC technical committees. He is also a member of the PSTC training faculty and still consults with industry companies. It is fitting that it will be to Serra that Johnston will turn over his entire library when he finally decides to slow down.

SHARING PRACTICAL KNOWLEDGE

In 2000, the PSTC published Johnston’s book, Pressure-Sensitive Adhesive Tapes: A Guide to their Function, Design, Manufacture and Use. The widely recognized volume is essential for those in the tape industry and includes information on how PSAs work, PSA formulations, tape backings, tape design, and tape testing. “It is to the vast majority of others who daily keep the adhesive tape industry alive that this book is both targeted and dedicated,” he says of the book Johnston is distinguished as a true expert in the field of PSA tape technology and testing. In addition to his prolific contributions to the PSTC (and the tape industry in general), he has written technical papers published by the Adhesion Society and TAPPI. He authored the chapter on physical testing of PSAs in the Handbook of Adhesive Technology, edited by Pizzi and Mittel. Johnston has also spoken at numerous industry technical conferences on the fundamentals, manufacturing, testing of and problem solving related to PSA tapes. During his 61+ years in the pressuresensitive tape industry, Johnston has worked with “every type of pressuresensitive adhesive system, every industry, consumer and medical group of tapes, every conventional manufacturing process and every related test method,” he says. He has designed numerous types of adhesive tapes by taking them from an initial concept through product development, manufacturing scale-up and 34

onto full production. Johnston has also designed several unique test methods and carried out fundamental research into the nature and behavior of PSA systems.

A TROVE OF INFORMATION At 85 years of age, Johnston shows little evidence of slowing down and absolutely no sign of losing his passion for the subject of his life’s work—PSA tape. For the past several years, he has been most interested in how to “pass the torch” of PSA tape and testing technology knowledge to others who match his passion and intensity. “As an industry, we can’t forget or lose sight of the accomplishments and knowledge compiled by industry giants like Carl Dahlquist and others,” he says. As one of those industry giants, Johnston has much in the way of accomplishments and knowledge to share. The first step in passing the torch was for Johnston to find someone in the tape industry who would give a home to, and find a continuing use for, the tremendous amount of data and information on pressure-sensitive tape that he had compiled during his career. The data includes his original research notes, industry information, product information, technology and patent information, published papers and articles, ideas on PSA testing, and much more. Enter Jerry Serra, the current technical advisor for the PSTC. He retired from Berry Plastics Corp. and its subsidiaries after 30+ years of service in the tape

What about all the technical knowledge and tape testing experience Johnston keeps in his very sharp mind? He thinks he may have found a new way to pass that particular torch. Dave McCann, director of R&D at Chemsultants International, began discussing and collaborating on a paper with Johnston in July 2010. McCann was in the process of completing research and writing a draft of the paper on alternate pressure-sensitive tape test methods for presentation at the 2011 PSTC Technical Conference. He was certain that it was an opportune time to bounce some ideas off Johnston to make certain that he was on the right track. Johnston was more than happy to travel to Chemsultants to discuss the project with McCann. However, as usual, Johnston ended up doing so much more. Johnston spent nearly two days at the Chemsultants facility in Mentor, Ohio, to work with McCann on a variety of testing methodologies that could evaluate situations where PSA tape products are expected to withstand very small stresses over a long period of time—especially where standard speeds or static test methods may not define the performance of the tape very well. The goal of the work was to employ small stresses (low weight or force) and/or very slow rates (such as 0.02 in./min) to reveal differences in the product performance or potential causes of product issues that may not be apparent when employing standard PSA test methods.

TESTING PEEL ADHESION When testing peel adhesion, the angle of peel usually determines which type of stress is applied to the adhesive. In 90° peel tests, the tensile modulus is revealed while all other angles of peel are a blend of tensile and shear modulus. To test the liquid properties of the adhesive in a slow deformation, it is necessary to keep the adhesive test area a constant (such as is done in shear testing). The issue with gathering tensile modulus information in a standard 90° peel test is that the area being tested is constantly changing as the peel front October 2011

progresses. In order to clearly understand the tensile behavior under slow strain, Johnston and McCann needed to change the geometry of the test to use a set area of the adhesive under test. Johnston suggested looking at the butt tensile test, which he developed in 1968. Some of the work they did to evaluate low stress/slow rate PSA deformation was completed using a probe material analyzer (ChemInstruments PMA-1000). The unit was helpful in performing tests on a variety of PSAs due to the ability to program both low forces and very slow speeds into the test protocols. In addition, they performed static peel adhesion and dynamic shear test methods on other ChemInstruments test units. McCann and Johnston initially looked at three test configurations for butt tensile tests: a metal probe brought into contact with the adhesive surface on a flat plate; a rectangular, flat metal probe with the adhesive tape wrapped around the panel and secured, then brought into contact with a test surface; and two rectangular, flat-faced panels with adhesive tape wrapped around both panels, brought together adhesive-to-adhesive. With all three configurations, the surfaces are brought together for a set time and pressure to allow the adhesive and test surface (or other layer of adhesive) to deform and bond well. They decided on the third configuration for much of their testing, which was done at a very slow rate (in the range of 0.01–0.02 in./min). As the adhesive is put under strain during butt tensile testing, it is typical for visible tendrils to be formed as the polymer chains are pulled (see Figure 1). On one sample that Johnston and McCann evaluated, the initial peak and the sharpness of the slope indicated more of the elastic component of the adhesive. The area under the curve gave them the total work done in separating and stretching the adhesive layer. The length of the tail indicated the liquid component of the adhesive. When an adhesive is crosslinked, as in this case, a secondary peak will appear; the peak becomes more predominant with increased crosslinking. The butt tensile test provides a graphic test result with much more information than the single point determined by the standard static shear test (see Figure 2).

technical team. Testing project leader Cheryl Saqqa had also been working with McCann on the issue of testing very small stresses over a long period of time. Johnston spent time with Saqqa discussing the similarities and differences in the test results, as well as information provided by static shear vs. dynamic shear testing. Not only was the information relevant to the PSTC paper, but it also gave Saqqa a new perspective on the impact of small forces and how they actually generate levels of adhesive debonding over time. She said this is information will be very useful in her day-to-day adhesive testing work at Chemsultants. Johnston didn’t limit his teaching and “passing the torch” opportunity only to the issue of testing PSA tapes. He made time to talk to Berry Decker,

Ph.D., technical project manager, and Mike May, development chemist, of the Chemsultants Product Development team. Both are involved in projects for clients who are interested in developing new products, reformulating adhesives with alternate raw materials or simply modifying an existing product to address performance issues or problems. Johnston once created 18 new PSA tape products in 18 months, so he is the ideal mentor to provide insight and guidance on the product development process, adhesive formulations, raw materials selection and product performance problem solving— the very issues Decker and May were facing. As usual, Johnston had a great deal of information and suggestions to pass along, proving that he has seen and done it all over the past 61+ years. Adhesives & Sealants Industry

PASSING THE TORCH FINAL CONSIDERATIONS

Johnston and Cheryl Saqqa discussing shear tests.

Johnston spent a considerable amount of time with the Chemsultants staff, both in the lab performing tests and in discussions about testing, adhesive formulation and performance. He said he saw in McCann, Saqqa, Decker and May “a fire in the belly, a passion for what they are doing” that he says is unfortunately becoming rare these days. According to McCann, the Chemsultants team “learned a lot and has an even greater respect for one of the giants of the tape industry than they did before.” John Johnston found a great way to pass the torch to a very receptive group, and Chemsultants has found a new partner to further increase the level of the PSA tape technical and testing expertise the company brings to the market. It is a winwin situation for everyone.

CASE STUDY

structural adhesives for bonding the molded 22.5-sq-ft GRP sections together, as well as the sections to the steel frames that are used to mechanically fix the sections to vertical steel pillars on the hotel exterior.

Miraplas factory. The nine elliptical sections were made from eight individual GRP pieces bonded together with Crestomer structural adhesives. A metal clamping frame was specially designed by Miraplas to hold all the parts in position during bonding. The most challenging aspect of the architect’s design was the production of the nine large curved triangular and elliptical sections. It proved most cost effective to produce these sections by making separately molded, 5-mm-thick GRP laminate parts and bonding them together. All the GRP parts were produced using an isophthalic resin, three layers of glass matting and an isophthalic gelcoat. Once molded, the eight separate GRP parts for each triangular section were accurately positioned in the metal clamping frame and bonded together. Crystic Crestomer 1152PA structural adhesive was applied using a pneumatic gun. The steel frames for mechanically fixing the GRP sections to the hotel wall were also bonded into place with Crystic Crestomer 1152PA. In some confined areas, hand guns with cartridges of Crestomer Advantage 30 were used. Miraplas, which has a purposebuilt, 44,000-sq-m composites molding factory located in Monforte del Cid in the south of Spain, has traditionally specialized in manufacturing large GRP tanks and related parts used in waste water treatment, water purification and desalination plants. For this hotel project, most of the GRP parts manufactured by Miraplas were produced by resin transfer molding (RTM) light closed molding; others were produced by hand layup. With the technical assistance of Jose Manuel Bey Garcia, an independent specialist consultant in RTM processing and the appointed hotel project technical advisor, the company has expanded its manufacturing capabilities in RTM closed molding over the last 18 months. Miraplas can now fabricate a wider variety of large complex GRP shapes for industrial and building and construction applications, such as doors, tank covers, curved cladding, cylindrical-shaped parts, and wind generator blades.

tural adhesives that have proven to be successful in a variety of building and construction applications, including cladding panels on bridges, as well as in many fiberglass marine applications in both hulls and decks. Reliable, longterm structural bonding of composite and metal substrates is achievable provided the recommended surface preparation is carried out prior to bonding. “Having used Crystic Crestomer adhesives for many years on several other projects, I was able to recommend their use for this project with great confidence that they will provide a guaranteed, reliable long-term bonding performance,” said Bey Garcia. In this type of application, bonding also helps to significantly reduce the overall weight of the final GRP section while offering additional benefits in pro duction efficiency, particularly when using pneumatic application guns instead of 380-ml cartridge hand guns where possible for larger sections.

Sidewall and bottom scrapers can also be installed to allow heat transfer between the vessel jacket and batch material. Shear levels and flow patterns in the PDDM can be fine-tuned because the stirrers and dispersers are independently driven and controlled. Solids are incorporated into viscous bulk material, and stubborn agglomerates can be dispersed regardless of product flow characteristics. Phone: (800) 243-ROSS Web: www.mixers.com

DYMAX RADIOMETER

The ACCU-CAL™ 150 is reportedly a simple-to-operate radiometer that offers repeatable measurement of UV light, which simplifies both the validation and monitoring of a UV light-curing process. The instrument can measure UV light up to 10 W/ cm2 emitted from stationary light-curing flood lamps or lamps used in conveyorized processes. It can be used to determine intensity (measured in mW/cm 2) or total energy as derived from intensity and exposure time (measured in mJ/cm 2). The use of radiometers in application processes is critical to ensure that any changes to the properties of curing energy are identified. Radiometers establish process parameters and, when maintained, help ensure consistent production quality, which results in reduced scrap and increased throughput. Web: www.dymax.com

ASK

AD INDEX

DR.DAVE

QUESTION: We apply our epoxy adhesives automatically and need to ensure that the adhesive has been mixed correctly and that it has actually been applied to the part. How can we accomplish this, other than having someone actually observe it visually? ANSWER: Epoxy adhesives, which comprise both the adhesive component and the hardener, are usually mixed with a static mixer. It is possible to use and monitor automatic flow controllers on both components of the adhesive. However, the most common way to determine the correct mix ratio is to periodically take a sample of the mixed adhesive and measure its properties, including density, cure speed, bond strength, etc. A few years ago, a major adhesives manufacturer collaborated with an auto company to develop a novel method for controlling the mix ratio of two-part epoxy adhesives. They discovered that the mix ratio can be continuously measured via a tagging system that incorporates microscopic stainless steel-coated glass bubbles in one component of the adhesive. The bubbles are detected by two eddy current sensors integrated into the dispensing equipment. This technique enables 100% knowledge and control of the dispense ratio. A few methods can be used to detect your adhesive on the parts. One standard method is to incorporate a fluorescent agent into the adhesive and use a fluorescence detector to monitor its presence. Photo cells or a camera system can also be effective. If you use a three-dimensional camera system, you can measure the width, height and position of the bead of adhesive. QUESTION: What would you recommend as a general-purpose wood adhesive? ANSWER: There are several types of wood adhesives, though craftsmen tend to refer to these as glues rather than adhesives. The traditional white glues, or carpenters’ glues, usually do a good job, as do tough acrylics or special formulations of cyanoacrylates. One-component polyurethane adhesives have also become popular in recent years. These adhesives have a single component and depend on moisture for curing. The moisture is sometimes available in the wood or the atmosphere, but it is common practice to dampen the surface before applying the adhesive. One has to be careful to use the right amount of adhesive and to clamp the parts, because the adhesive generates foam on curing and tends to expand.
