Adhesive Technologies

Global number one

Our products and services have a worldwide presence. Thanks to the breadth of our portfolio, they are used in many different markets. These include the packaging, metals, automotive and electronics industries as well as aerospace applications. Our products can be found in many objects that touch our lives every day: from packagings, books, cell phones, furniture and shoes to cars and airplanes.

Adhesive Technologies is the global leader in adhesives, sealants and surface treatments. This applies just as much to technological and environmental aspects as it does to the health compatibility of our products. As a result, we are in a position to combine economic benefits for our customers with responsibility toward people and the environment.

More value for our customers

In our view, sustainability and efficiency are inseparably linked. Our long-term goal is not only to triple our own efficiency, but to help our customers to boost their efficiency as well. We continuously optimize our products so that they deliver more value to our customers and help them achieve their own sustainability goals. Often, our solutions combine economic benefits with progress in the areas of environmental protection as well as occupational health and safety and consumer protection.

With our packaging adhesive Technomelt Supra 1000, for example, we are demonstrating our constant dedication to supporting the packaging industry. The Henkel product helps to improve sustainability performance at our customers, since up to 40 percent less adhesive is required for the same volume of packagings. Moreover, the superior quality of the adhesive reduces the reject rate.

Together with the TimberTower company, Henkel has been able to herald in a new era in the wind power industry. The roughly 100 meter high tower near Hannover, Germany, is the first wind power plant to be built of spruce timber. The wooden structure has been bonded throughout using special techniques – with different adhesives from Henkel’s Purbond brand. Switching to timber as the construction material allows taller towers to be built, which results in better efficiency with a higher electricity yield.

Boosting efficiency in the electronics industry

Manufacturers in markets such as the consumer electronics, aircraft and automotive industries, need underfill materials to provide drop and shock protection for their electronic devices. With Loctite UF3810, Henkel has developed a high-performance, easy-to-use underfill product that meets the complex requirements for production of sophisticated devices in entertainment applications, for example. It is halogen-free and cures fast at 130 degrees Celsius thanks to its low glass transition temperature, thus helping to keep energy use down in manufacturing operations.

Award for Cachaça project

Agorex

The Cachaça project was recognized as one of the most sustainable technologies in 2012 by the Chile Verde initiative and awarded the Chile Verde 2012 title. The project involves a novel kind of technology developed by Henkel in Chile. In this project, Henkel Chile is replacing the fossil solvents in products of the Agorex and Pritt brands with ethanol. This is derived from sugar cane – just like the well-known Cachaça alcoholic beverage after which the project was named. Ethanol is currently the most environmentally compatible organic solvent. Since 2012, Henkel has also been using the Cachaça technology for products in Brazil and the USA. www.agorex.cl

Safety as a top priority

The health and safety of our customers and consumers is a top priority for us. We thus work constantly around the globe to set new standards with our products. An important issue for us is the use of solvents in adhesives for consumers and professional craftsmen. Replacing solvent-based adhesives by alternative solvent-free systems has therefore been a goal of our researchers for many years. One example of this is the Pattex 100% adhesive which was introduced across Europe in 2011. It is part of the Pattex range that is composed almost exclusively of solvent-free products that do not compromise on bonding power.

In the food industry, the regulations for packagings became tighter than ever in 2011. Henkel is the first adhesive manufacture in the world to offer a complete spectrum of low-migration products for these applications. All of the products are water-based, plasticizer-free and virtually eliminate the migration of substances from the laminated material. These adhesives are also up to 30 percent more economical to use while providing the same or better bonding performance.

Partnering for sustainable products

Sustainability requires concerted knowledge-sharing and action by all those involved along the entire value chain – from raw materials suppliers through to consumers. We therefore work with strong partners to find efficient solutions for even better eco-compatibility and improved occupational health and safety and consumer protection.

One example is our collaboration with the automotive industry, where the use of Henkel technologies in car manufacturing can bring about numerous improvements. These range from reducing the number of necessary process steps to saving energy and water, and helping to build lighter and safer vehicles.

Adhesive bonding is increasing replacing conventional joining techniques such as welding, riveting and bolting. Often, it is the only way to join parts made of dissimilar materials. The use of composite materials helps to reduce the overall weight of the vehicle and hence its carbon emissions. Adhesives also increase the rigidity of cars, seal seams, reduce the number of weldments, and make cars more resistant to corrosion. Specialty adhesives also help to dampen noise.

The benefits of bonding in vehicle construction provide good reason for Elddis, an English manufacturer of caravans and mobile homes, to cooperate with Henkel. Adhesives from Henkel have, in fact, already made it possible to replace 90 percent of the bolts in Elddis products, and the company intends to use even more adhesives in the future.

The significance of strong partnerships is also illustrated by the new alliance with the Nordson Corporation, a leading manufacturer of precision dispensing systems for adhesives. This helps to optimize the use of products in our customers’ facilities, since the new dispensing system stops material wastage and reduces downtimes.

Innovation through life cycle assessments

As the global leader in adhesives, we are aware of our responsibility and want to demonstrate our progress in sustainability in a transparent manner. The extensive experience of our research and development staff, in particular with the use of life cycle analyses, helps us to identify suitable starting points for improvements across our product portfolio. Here we consider not only the composition and production of our own products, but also the applications in which they will be used and the production processes at our customers.

The Henkel-Sustainability#Master includes a matrix for evaluating a product category on the basis of our value chains and our six focal areas. This makes it possible to identify hot spots, or areas with the greatest relevance for sustainability, and to compare two products or processes in a transparent and quantifiable way.

It allows us to show our customers which areas offer the greatest potential for improvement.

Advice, training and dialogue

Our understanding of quality does not stop with the development and sale of high-performance products. All around the world, we offer service and advice to our customers. In North America, Henkel is now offering a new way to help its industrial customers troubleshoot problems. The support is provided by video conferences with live streaming. The images can be broadcast in up to three places at once, so that specialists from different disciplines can contribute their expertise. At Ceresit training centers in Central and Eastern Europe, craftsmen learn how best to use our building products. We teach them professional techniques for applying Ceresit façade insulating products. These play a key role in reducing energy use in buildings.

“As market and technology leaders, we develop solutions that combine economic benefits for our customers with responsibility toward people and the environment.”

Henkel-Sustainability#Master – Loctite Max 2 in comparison with epoxy resins

The Henkel-Sustainability#Master reveals the sustainability profile of Loctite Max 2. Because of their light weight yet high strength, composite materials reinforced with carbon or glass fibers are becoming more and more important in the construction of fuel-saving vehicles. Loctite Max 2 is a polyurethane-based resin which has been shown to deliver benefits in a number of categories compared with the epoxy resins normally used. The carbon footprint for polyurethane is significantly smaller than that of an epoxy-based system. The resin cures very much faster and impregnates the fiber material more easily, thus reducing the necessary injection times. Shorter cycle times result in economic benefits for the customer.
