New additives for high-performance bioplastics

Written by

In view of dwindling reserves of fossil resources, industry is showing growing interest in bioplastics. However, compared to conventional high-performance plastics, these have their limitations – among other things in terms of stability and strength. In cooperation with Tecnaro, Henkel has now succeeded in developing new high-performance polyamide additives based on renewable raw materials that can significantly improve the performance of bioplastics.

The use of plastics components based on renewable raw materials is seen as the way forward in the plastics industry. Ecologically, such bioplastics are far superior to classic, petroleum-based products. The growing diversity of bioplastics applications is being accompanied by rising expectations on quality and processing characteristics. In cooperation with compounder and biopolymer specialist Tecnaro, Henkel has developed new polyamide additives that upgrade the performance of bio-based plastics.

Containing a large proportion of natural raw materials, the additives of the Macromelt brand are ideal for the production of industrial plastics. This has become possible through the use of dimer fatty acids based on natural oils (e.g. rapeseed and tall oil). Along with a general increase in the proportion of bio-sourced ingredients, the new additives also have a positive impact on the performance profile of bioplastics. Impact resistance and fiber-matrix adhesion are much improved by these additives.

Depending on the plastics formulation, the additives are capable of reducing processing temperature, in some cases considerably. This diminishes the stressing of the fibers employed, with a positive effect on stability and appearance.

By developing Macromelt polyamide technology further, Henkel is thus helping to improve the quality and usability of bioplastics and paving the way for further high-end applications.

Tecnaro is one of the world’s leading companies in the biopolymer sector with its Arboform, Arboblend, Arbofill and Arboflex families of materials. Thanks to the many years of successful cooperation between Henkel and Tecnaro, tailored biopolymers and composites containing Macromelt additives are already expanding Tecnaro GmbH’s broad range of biomaterials.

Henkel invests heavily in young engineers

Written by

For three years now, Henkel has been engaging in promoting young engineers. In addition to offering numerous training programs, participation in the annual Formula Student contest for engineering students at the Hockenheimring has become a central component of Henkel’s commitment in this area. The special award for best use of adhesive, which Henkel instituted in 2009, was won this year by the team from Bayreuth University.

The design competition attracts a great deal of interest internationally, with teams from colleges and universities from all over the world taking part. It ranks as a kind of unofficial Olympics for engineering students. Competing against all other entrants, the teams have to design and build the prototype of a new racing car from scratch, present it as a business case, and test its performance in various trials and a final race. 78 teams in the Combustion category and 31 more in the Electric category made it to the final round to be judged at the Hockenheimring at the beginning of August.

For the General Industry business of Henkel as one of the main sponsors, the five-day event is one of the highlights every year. Up to eight Henkel adhesives experts were available at any time to give the contestants advice or lend a helping hand – in the pits, working on the cars themselves, or at the Henkel stand. The latter was not only well-stocked with high-performance repair and maintenance products from Henkel’s Loctite and Teroson brands, but also featured workbenches and even a heating cabinet to accelerate curing of different adhesives.

Special award for best use of adhesive
In order to inspire these enthusiastic students to become even more creative, Henkel established a special award for the best use of adhesive throughout the whole contest. Submissions are judged on the attractiveness and creativity of the bonding application, the way the adhesive was selected and verified, the presentation made to the jury, and the students’ knowledge about bonding technologies.

From a large number of submissions, seven teams made it through to the final round. The award went to Bayreuth University, ahead of last year’s winner Zwickau University, with Coburg University taking third place.

“Last year, the entries were already of a very high standard,” says Rudolf Neumayer, Head of Application Technology, Industrial Adhesives, Europe. “But this year, they raised the bar several notches further. This trend shows that we are definitely moving in the right direction with our educational approach.”

Henkel’s level of engagement in the entire contest earned high praise, not only from the contestants themselves but also from the organizer. “Henkel was present with a large team and often performed last-minute rescue jobs,” said Ludwig Vollrath of VDI (the Association of German Engineers), who is in charge of the event. “People were highly impressed by that.”

Multiplier effect and greater awareness of the brands
Henkel therefore also profits from this commitment. “The five-day finale of the contest was itself attended by around 2,500 students, professors and design specialists,” says Patricia Silva, Marketing Manager, General Industry. “No other event throughout the year draws so many highly interested people with a will to experiment. Having such a representative target group all in one place means that we can achieve important multiplier effects and heightened awareness of our brands.”

“Bonding is simply the most dependable solution!”
This view is shared by many people, including Moritz Berard (23), a student from Karlsruhe University, who participated in the contest. “For me, bonding is one of the best solutions there are, and easily the simplest and most dependable one,” says Berard summing up. “It opens up whole new worlds and gives an immense amount of design freedom.”

Although more and more students beginning to realize this, Henkel’s engagement is actually a medium to long-term investment that not many companies take the trouble to make. But the benefits can already be estimated today, thinks Alfred Kaltenbach, Area Sales Manager for Baden-Württemberg of Henkel’s General Industry business.

“In Germany alone, about 2,200 young engineering graduates start their careers by going straight from university into private enterprise, where sooner or later they will occupy key positions,” he explains. “When engineers who have previously learned about our adhesives and sealants then design new components, they will already be familiar with all the advantages of adhesive bonding technologies and will include this joining technique in their design considerations right from the beginning. This way, adhesive bonding, which was unfortunately often regarded as a last resort in the past, will gain the status it deserves. And we intend to make sure that the young engineers’ experiences with Henkel have been entirely positive.”

Breaking new ground in materials innovation, Henkel Electronic Materials has announced its success with a revolutionary silver (Ag) sintering technology that enables high volume production of modern power packages in a process that does not require pressure. In its market debut, Henkel’s Ag sintering capability has been designed into Ablestik SSP2000, a high reliability die attach material well-suited for use with power modules such as IGBTs and high power LED products.

Sintering is a process in which particles are joined together by heating the material in a sintering furnace below its melting point until there is particle adhesion.  Conventional Ag sintering is achieved by applying both heat and pressure to the material, or device, until the metal joint is formed.  The drawback to the pressure application technique in semiconductor packaging, however, is its volume limitation, as devices must be processed individually on capital-intensive die bonding systems.  With Ablestik SSP2000, because the silver particles are joined via a unique surface tension mechanism, the pressure requirement is eliminated and the material can be cured in a standard batch oven at a temperature as low as 200 degree centigrade.  In addition, Ablestik SSP2000 can be processed on standard die bonding systems, eliminating the need to reinvest in specialist equipment and making the transition from existing materials simple, fast and cost-effective.

“The ability to now exponentially increase UPH from traditional silver sintering techniques at roughly 30 units per hour to a remarkable 6,000 units per hour with the Henkel technology is incredible,” enthusiastically explains Henkel’s Dr. Michael Todd, Vice-President of Product Development and Engineering.  “Now, semiconductor packaging specialists can have high volume and high reliability with a silver sintering material.”

While high UPH is a central advantage of Ablestik SSP2000, even more notable is the material’s thermal resistance and reliability.  When compared to high-lead soft solders, which are the current material of choice for power semiconductor devices, Ablestik SSP2000 has far superior power cycling reliability.  In power cycle testing where solder failed at 200 cycles, Henkel’s Ag sintering technology was able to reach more than 2,000 cycles before the first failure.  With thermal conductivity and thermal resistance that are superior to that of solder, Ablestik SSP2000 offers better performance and reliability. For high power devices such as IGBTs, that presents tremendous latitude as compared to traditional solutions.

“Because of Ablestik SSP2000’s superior power handling performance, IGBT designers and manufacturers are now able to reduce the number of chips in a package and save on valuable device real estate,” comments Todd.  “This material provides a technical solution that popular high-lead soft solders simply don’t have. What’s more, all the performance is achieved in a non-pressure process with lower curing temperatures, which is icing on the cake!”

Not only do semiconductor packaging specialists want higher throughput, higher performance materials, but are also actively seeking viable replacements to high-lead solders – particularly in the power device segment. The RoHS deadline for the elimination of lead-based materials from the power device market is currently set for 2014, which means that in less than three years suitable alternatives must be in place.  For power device manufacturers, Henkel already has the solution with the first Ag sintering die attach material of its kind.

As Todd concludes, the flexibility of Henkel’s solution is simply untouchable.  “The lead-free advantage, design latitude, thermal and electrical performance, reliability and high UPH capability – it’s all there.   Our silver sintering technology is already proving its worth in the power device market, has shown great promise in the high power LED market and, frankly, is ideal for any application that requires high thermal capability in high volume.  This will no doubt be a game-changer.”

Over the past decades, structural adhesives have evolved into effective and dependable alternatives to conventional joining techniques such as bolting, riveting and welding. They can be used to bond almost all materials commonly employed in industrial manufacturing. One essential aspect is selecting the right bonding solution for each particular construction. But which adhesive solutions are available and which factors must be considered in order to get the best results?

Structural adhesives are used to join a variety of similar and dissimilar materials effectively while achieving an optimal distribution of mechanical loads, stresses and vibrations. The range of applications stretches from bonding of single-use medical articles through to the assembly of heavy equipment. In order to ensure the structural strength of the bondlines, the structural design of the materials to be joined and the choice of adhesive technology must be very carefully evaluated. Different constructions will pose different structural bonding demands.

Structural design considerations
The strength and long-term durability of a structural adhesive bond depend especially on the adhesive used, the materials involved, and the loading to which the construction will be exposed. The loads, in other words the external forces acting on a construction, can be classified according to five types of stresses: tensile, compressive, shear, peel and cleavage forces. For each type of loading, there is an adhesive technology which optimizes the ability to withstand the forces acting on the component in question.

Tensile force is the force acting on a bondline when the component is pulled or stretched in a direction perpendicular to the bondline and the substrates it joins. With a pure tensile load, the stress distribution within the bondline is relatively uniform. The same load acts on each part of the bond area. This is also true of compressive loads. A compressive force is an external force acting on a joint when the bonded materials are subjected to pressure. In practice, pure tensile or compressive loads are generally rare and usually also involve a degree of peel loading.

In industrial constructions, the most common loads are shear, peel and cleavage forces. A shear force is the force acting on a bondline when the two joined parts are pulled in parallel and opposite directions. Peel and cleavage forces are very similar and are the least desirable forces acting on a structural bondline. These two forces occur when a load is applied to the end of a bondline, being of a peel nature when at least one of the parts can be easily deformed.

Although shear loads are by far more desirable than peel or cleavage loads, in all these three types of loading, the resulting stresses are distributed unevenly across the bondline. Adhesive bonds subjected to shear loading exhibit stress peaks at both ends of the bondline, while the stresses in the middle region are less intense. This load mode is probably the most frequent, especially in overlapped joints, which are the most common adhesively joined configurations. However, peel loads result in high stress concentration at just one end of the joint. If the adhesive starts to come away from the substrate at the edge of the bondline, small cracks will then propagate throughout the entire joint. An effective adhesive bond is therefore characterized by uniform stress distribution, which is achieved by selecting the adhesive that will deliver the best performance for that particular construction.

Adhesive technologies – An overview
In industrial manufacturing, adhesives are playing an increasingly important role in the production of many different kinds of products. They offer a number of advantages that conventional joining techniques cannot match. Compared with traditional assembly methods, adhesive bonds are superior in the presence of dynamic stress, thanks above all to their flexible nature. Rivets or bolts can only transmit forces over a very localized area (point loads), whereas in an adhesive bond, the stress distribution or force transmission is spread over the entire area of the bond. In addition, the parts to be bonded are not weakened by the drilling of holes.

The low heat build-up is another key criterion when joining parts that already have their final surface finish, for example chrome-plated steel. As non-conducting materials, cured adhesives also have an insulating effect, thus preventing contact corrosion.

The substrates involved and the demands made on the final construction are deciding factors when selecting the adhesive to be used. Depending on the field of application, various adhesive technologies with specific product properties are available for structural bonding.

Epoxies
The most widespread class of adhesives used for structural bonding are the epoxies. They are found in automotive and aircraft manufacturing as well as in the building and construction industry. Their big advantage is that they can bond both metals and plastics. Moreover, they are extremely durable, show a low tendency to creep, and only minimal shrinkage on curing. Depending on the type, they can withstand continuous exposure to temperatures ranging up to 100 – 200 degrees Celsius. A further advantage is their very good chemical resistance, although they are generally rigid. Epoxy adhesives offer a broad potlife range of five minutes up to two hours. A long potlife can be an advantage when the parts to be joined require some time to maneuver or when they have to be repositioned after they have been assembled.

Epoxies are available as one-part or two-part systems. In one-part systems, the resin and hardener components are already mixed in the correct ratio during production and only begin to react with each other when exposed to heat. Two-part systems consist of separate resin and hardener components which are only mixed directly before application. When using two-part systems, it should be remembered that the chemical curing reaction begins immediately after mixing.

Polyurethanes
Polyurethane adhesives are also available as one-part or two-part systems. They come in a large variety of viscosities, with a broad range of cure times and different specifications regarding chemical resistance. The degree of crosslinking and hence the final bond strength is determined by the combination of raw materials contained in each of these adhesive systems. Therefore, perhaps their most relevant feature is their capability to match virtually any mechanical requirement, ranging from very rigid grades to extremely flexible adhesives. In addition, they show good resistance to many kinds of solvents. With this performance profile, polyurethanes are therefore widely used for bonding tasks in industries with applications as diverse as bonding windshields to car bodies or assembling rotor blade shells for wind energy plants.

Acrylics
Acrylic adhesives offer a broad adhesion capability. They are able to bond a wide range of varied substrates, including most thermoplastics, and exhibit a good balance between high strength and some flexibility, which makes them one of the most frequent choices when dynamic loads are involved. Another interesting feature of this chemical family is their fast cure speed, which brings additional cost-saving opportunities in the manufacturing process. However, they usually smell and, therefore, when a large adhesive amount is involved it is recommended to apply it in well ventilated areas.

Acrylic adhesives can be either a one-part adhesive with an activator or a two-part adhesive system. The one-component adhesives do not require any mixing. The adhesive is applied to one substrate, the activator to the other, and the curing process only starts when the two surfaces are brought together. In two-part systems, the activator and the adhesive are mixed together using a mixing nozzle and then applied to one surface.

Silicones
In contrast to the adhesive systems described above, all of which are based on organic chemistries, silicone adhesives have an inorganic backbone. Unlike their organic counterparts, silicones remain highly elastic even at temperatures as low as minus 90 degrees Celsius. They are also able to withstand continuous service temperatures of up to 200 degrees Celsius and are exceptionally resistant to UV radiation. Applications where they can be employed as adhesives are in areas where there is a need for high flexibility and high-temperature performance capability. In addition, they show good resistance to aggressive chemical substances and excellent resistance to moisture and weathering.

Silicone adhesives are available as one-part or two-part systems. The range of applications served by one-part silicones stretches from assembly of clothes irons to vehicle manufacturing, and electrical engineering to special tasks in the aerospace industry. Two-part silicones are used in the electrical industry, household appliance manufacturing, and in the vehicle industry. They are particularly useful where atmospheric moisture levels are too low to permit completion of the curing process of one-part silicones or where an acceleration of the production process is desired.

Silane modified polymers
Silane modified polymer adhesives, often referred to as MS polymers, show very good adhesion to many different substrates. The bonds have a continuous thermal resistance of approximately 80 to 100 degrees Celsius, high elasticity (resulting in good resistance to deformation even at low temperatures), and are highly resistant to UV radiation and weathering. Adhesives based on MS polymers are used to bond parts in rail, car and container construction, in equipment and apparatus assembly, metal and sheet metal processing, solar engineering, façade and window installation, air conditioning and ventilation systems, cleanroom equipment, and in a series of building and construction applications. The advantage of this adhesive category is that it is free of silicone oils and therefore presents no incompatibilities during downstream painting of bonded parts.

The capacity and performance of the diecasting industry is greatly dependent on the development of efficient and sustainable manufacturing technologies. Henkel will be presenting a truly future-aligned product portfolio at GIFA 2011, encompassing innovative solutions right along the entire value chain and offering industrial users all the synergy benefits ensuing from the merger.

High-quality and corrosion-resistant diecast components pass through a number of process stages before they can be deemed ‘complete’. Aside from the actual casting process, machining, component cleaning, pretreatment and final assembly all have a decisive influence on their value. Henkel is able to offer premium products covering all the manufacturing stages mentioned. Indeed, the company’s portfolio includes everything from high-performance lubricants and lubricoolants to specialty cleaners, conversion coatings, adhesives and sealants. Henkel also supplies specific application equipment for water free systems compatible with the specific fluids that it handles. Henkel is able to ensure the ideal interplay between all the process stages, securing maximum value added at every turn.

Excellent tribological performance, efficient coating application
Henkel’s lubricants and mold release agents of the Deltacast range are indispensable aids for the casting process itself, delivering first-class performance even under conditions of high temperature. They help to extend the service life of the molds, reduce scrap rates and increase productivity. The Deltacast CP-range are water-based release agents specifically designed for the pressure die casting, thixo-casting and squeeze casting of aluminum, magnesium and other non-ferrous metals. The CG-range are specific formulations for the gravity and low pressure die-casting of aluminum and non-ferrous metals. For the perfection in die management technology for pressure die-casting of aluminum and magnesium, Henkel has developed Deltacast Liquid Powder.

Despite the sophisticated production processes applied, expensive castings can sometimes be rendered unusable by porosity, blowholes or similar structural defects – unless, of course, they can be salvaged with Henkel Loctite-KID. This vacuum impregnation process enables flawed components to remain in the manufacturing process instead of being assigned to the scrap heap. Offering impressive properties such as good resistance against chemicals and solvents, a high level of thermal durability and effective resealing, the impregnating agents used by the system are approved by the major automobile manufacturers and OEM suppliers around the world. The impregnation process leaves the treated workpieces clean and free of corrosion and oxidation, enabling them to be further processed without any reworking. And the cured impregnant also remains resistant to oils, grease, most kinds of acid, liquid fuels, gases, coolants and solvents throughout the service lifetime of the components involved. For the impregnation of workpieces, LOCTITE offers a choice of an external full-service package or the tailored integration of a vacuum impregnation plant within the customer’s production process.

Focusing on the full value chain
As a world leader in the manufacturing of adhesives and sealants and based on decades of experience in industrial cleaning and surface treatment, Henkel is also in a position to supply customers with sophisticated solutions for cleaning and machining. Henkel’s P3 products are high-quality alkali, acid and neutral aqueous cleaners for efficient process, parts and maintenance cleaning. The enhance both th the efficacy and the reliability of the overall process, as well as the quality of the manufactured components. And for the machining stage, Henkel is able to offer high performance coolants which deliver economic metalworking and forming of light metals, cast iron, steel alloys and non-ferrous metals. Multan features have created an innovative push in metal operations including: High cleanliness, longer tool life, low scrap rate and reduced consumption.

Henkel is also setting new standards in metal pretreatment with its Alodine product group for chrome-free coating and anodizing processes. Given the ever-increasing concerns over environmental and health risks, the trend in the metal-coating industry is toward even more extensive use of chrome-free technologies – an area in which Henkel can already resort to more than ten years of research expertise. Its Alodine products offer ideal corrosion protection for aluminum, magnesium and light alloys while guaranteeing outstanding paint adhesion.

Last but not least, customers can also rely on the reliability of Henkel products for the subsequent component assembly phase. The company’s widely known adhesive under the Teroson brand offer multiple solutions for the structural bonding of metal and plastics, replacing conventional joining techniques such as welding and screw-fixing. Meanwhile, liquid gaskets of the Loctite brand are ideal for component surfaces of all shapes and sizes. These flange seals are resistant to oil, transmission fluids and water while also exhibiting impressively high temperature resistance.

Henkel at GIFA 2011
Visitors to GIFA in Düsseldorf, Germany, scheduled for June 28 until July 2, 2011, will find extensive information on the entire Henkel product portfolio at Stand J35 in Hall 11.

New methods and products for the fabrication of composite parts lead to easier and cost-efficient production processes as well as to higher end product performance. For its innovative benzoxazine prepreg resin used for a new composite tooling material, Henkel and its partner Airtech Europe were selected as a JEC Innovation Award finalist.

With the increased use of composite parts in almost all industries, there is a need to use more and larger composite tools. Current materials used are typically epoxy or bismaleimide (BMI) matrix composites. While these have demonstrated effective use of composites, both have disadvantages for large and high rate tools, for instance lacking stability at high temperatures or high moisture absorption. In cooperation with Airtech, Henkel has developed a resin technology which offers the solution to these and more difficulties.

Henkel Benzoxazine Resins with superior process performance
Henkel and Airtech worked closely to define the resin system requirements for an improved tooling pre-impregnated fiber – prepreg for short: The new composite tooling material using Henkel Benzoxazine Resin is designed for repeated cures at 185°C while maintaining good dimensional stability and vacuum integrity. Thanks to the characteristics of the Henkel Benzoxazine Resin, the prepregs are stable at ambient temperatures, and have a lower exotherm during the curing process which enables shorter cure cycles to be used for manufacture of thick tools without special precautions.

Successful launch of new tooling prepreg
In aircraft engineering, there is an ongoing trend toward lightweight construction.  Accordingly, the new tooling prepreg was very well received by the industry. For instance GKN Munich – a leading global supplier to the world's automotive, off-highway and aerospace industry – has quickly adopted the Beta prepreg as a tooling solution for stringer tooling on Airbus A350. The requirement was for a composite tooling system which would be easily machined on the non-moulded face and would provide long high temperature service life. Beta Prepreg meets those requirements and delivers additional benefits of reduced shrinkage, also greater ease and reduces cost of manufacture when compared to BMI tooling prepregs.

Henkel and partners selected as 2011 JEC Innovation Award finalist
With their advanced resin technology for composite materials, Henkel and its partners Airtech Europe and GKN Aerospace Germany were selected as finalist in the aerospace category of the 2011 JEC Innovation Award. With two international composites tradeshows in Europe and Asia, JEC is a composites network with 250,000 professionals from all over the world. The innovative benzoxazine resin technology will be on display in the Innovation Award Area the JEC 2011.

They are tested in line with the generally accepted global ISO test standard 10993. Loctite adhesives are subject to a continuous process of further development and correspond to the continually increasing technical and process-related needs encountered in medical engineering.

Highest level of safety thanks to the new Loctite AssureCure System
At the same time, along with adhesives technology the Loctite portfolio also provides the necessary equipment technology (hardware) for dispensing, curing and monitoring purposes. As a systems provider, Henkel offers the optimal interaction of curing and dispensing equipment and adhesive as the basis for perfect bonding. The revolutionary AssureCure System featuring a newly developed adhesive combined with a new monitoring system is being introduced at this year’s MEDTEC for the first time. The AssureCure system promises to provide a hitherto unrivalled level of reliability and precision in the production of medical devices. The combination of the most advanced adhesives technology and state-of-the-art equipment technology enable manufacturers of medical equipment to carry out assembly and the immediate testing and inspection of components in sequence. The brand-new system will be demonstrated exclusively at the Henkel stand.

The entire medical technology value chain at a glance
Based on its decades of experience in industrial cleaning and surface treatment, Henkel is also in a position of supplying optimal products to its customers for numerous other production steps. In this regard, the product line of the P3 brand of specialty cleaners increases the effectiveness and safety of the entire processes as well as the quality of the manufactured parts. Under the Multan brand name, Henkel also offers the first water miscable, bactericide-free cooling lubricant for the purpose of mechanical processing. This does not require the addition of bactericides as follow-up treatment, which not only simplifies handling during production but simultaneously significantly minimizes health-related burdens imposed on employees.

Henkel is also setting new standards in the field of metal pretreatment based on its nanoceramic coating technology Bonderite NT. Compared to conventional corrosion protection processes, costs for wastewater treatment, waste disposal, equipment cleaning and maintenance are considerably reduced due to the fact that Bonderite NT does not contain phosphates or toxic heavy metals. At the same time, the performance of the product is convincingly impressive. Bonderite NT leads to a marked improvement in corrosion resistance and paint adhesion.

Loctite – a success story

Written by

For over 50 years, Loctite has provided customers and consumers with advanced adhesive and sealing solutions. With over 5,000 patents, Loctite leads the adhesive category in the industry and it is superglue market leader for consumers.

Loctite is known to offer high-performance adhesives and sealants. It offers chemical products and equipment solutions for automotive applications, industrial manufacturing, as well as for electronics, aerospace and medical technology. Loctite products can also be found in the toughest applications for instance in Dakar race cars, in Terex special trucks for construction or to manufacture Porsche race cars.

The Loctite story began in the Trinity College basement laboratory of Dr. Vernon Krieble of Hartford, Connecticut, in 1953. Together with his son, Robert, also a Ph.D. chemist, this entrepreneurial chemistry professor developed a cure inhibition system for a unique liquid bonding resin that hardened in the absence of air – an anaerobic sealant. Loctite made its official public debut at a press conference at the University Club in New York on July 26, 1956. The promise of solving the age-old problem of loose nuts and bolts in machines and appliances – a problem, customers had long ago accepted as unsolvable – led to an incredible flow of inquiries. This laid the foundations for the brand’s philosophy of providing solutions to seemingly impossible problems.

In the 1960s, cyanoacrylates (also known as superglues or instant adhesives) were developed under the Loctite brand. In 1975, Loctite provided this technology, already proved in the industry, to the consumers market to fulfill the daily gluing needs also at home.

Silicones, epoxies, acrylics and the development of further generations of anaerobic and cyanoacrylate technologies and products followed.

Throughout its history, Loctite has continued to create markets by discovering opportunities where no one knew they existed. From its founding, based on a product that solved an “unsolvable” problem, Loctite has consistently achieved success through innovation.

With a brand history stretching back over fifty years, Loctite today leads the market in high-performance adhesives, sealants and chemical products. Marketed in more than 80 countries around the world, Loctite has been part of Henkel since 1997. Henkel is the leading global supplier of adhesives for consumers and craftsmen as well as for industrial applications.

The use of hotmelts for encapsulating electronic components is on the advance in virtually all sectors of industry. The hotmelt molding process reliably protects components – even those without plastic shells – from environmental effects and facilitates rapid and reliable processing. At the exhibition electronica 2010, Henkel is presenting an extensive range of Macromelt hotmelts for the most varied requirements.

The protection of electronic components by hotmelt molding is becoming increasingly established. Molding with hotmelts of the Macromelt brand has definite advantages over conventional methods in terms of application. Compared to classic plastics injection molding processes, processing takes place at a significantly lower injection pressure of 5-40 bar. The benefit of this is that even sensitive components can be readily encapsulated without being damaged. The advantage of Macromelt molding over 2K potting compounds is its much shorter cycle times of, in general, 10 to 50 seconds. In addition, since there is no longer any need for a separately produced shell, savings in production costs can be achieved in most cases despite the higher cost of the hotmelt adhesive.

Under the Macromelt brand, Henkel offers an extensive range of thermoplastic hotmelt adhesives, tailored in each case to the specific requirements. The Series 6 products are exciting not only technically but also environmentally, as they are produced from renewable resources. During their processing, no chemical reactions take place and no solvents are released. The most recent developments include Macromelt OM 671 with optimized cold flexibility. This universal product is intended for all electrical and electronic components (plugs, circuit boards, sensors, etc.) that have to be protected from external effects and are exposed to extreme temperature fluctuations. With service temperature range of -50°C to +140°C, Macromelt OM 671 displays exceptionally good low-temperature behavior.

In addition, Henkel’s portfolio also includes hotmelt solutions with specific properties for successful electronics encapsulation. Reliable protection outdoors is provided by Macromelt OM 648. Thanks to its high UV-stability, it is particularly suitable for applications with exposure to strong solar radiation and is used on the wiring of photovoltaic modules, for example. With another product, Macromelt OM 653, Henkel has achieved a significant improvement in hydrolysis resistance. Unlike standard hotmelt adhesives, the mechanical properties of this hotmelt change only slightly in contact with water. Macromelt OM 653 has successfully undergone the 85/85 test at a temperature of +85°C and humidity of 85% for 1,000 hours. For conventional hotmelts, this test often proves to be a stumbling-block, as it can permanently impair the adhesive’s mechanical properties. Macromelt OM 653, on the other hand, has almost unchanged values for tensile strength and elongation at break, even after drying.

Henkel also has a solution for the encapsulation of components that have to withstand the reflow process: Macromelt OM 730 even endures temperatures exceeding +200°C. Thanks to its one-component composition, it simplifies the production process considerably, as the plastic components used until now can be omitted. The temperature stability of Macromelt OM 730 also responds to the trend toward compact design in the automotive sector. With the electrics and electronics being shifted ever closer to the engine compartment, the shielding has to meet increasingly tough requirements.
