Bayer MaterialScience at the European Coatings Show 2015

„Inventing for you“

Customer-oriented inventions create value-added throughout process chains / New bio-based products for coatings, adhesives and coated textiles / Efficient, low-temperature coating for plastic components in cars / Innovative adhesive hardener for flexible packaging

Nuremberg, April 22, 2015 – “Inventing for you” – the Coatings, Adhesives, Specialties Business Unit of Bayer MaterialScience is putting the spirit of invention and innovation at the very heart of its global activities. This new strategy is also reflected in the company’s participation in the European Coatings Show 2015, the world’s largest trade fair for the coatings and adhesives industry. The event is taking place in Nuremberg, Germany, from April 21 to 23. At Stand 528 in Hall 4A, the company is showcasing new milestones with polyurethanes that offer extra benefits right along the value-added chains.

Bayer MaterialScience aims to identify trends and unfulfilled customer requirements early on and use innovative products and technology to provide value-added to partners along the process chains. The company uses inventions to help customers in the coatings and adhesives industry fulfill increasingly challenging requirements relating to the quality, sustainability, service life and aesthetics of products. New trends have to be identified early on and transformed into solutions that create value.

“We need to understand today what our customers will need from us tomorrow,” said Daniel Meyer, Head of the Coatings, Adhesives, Specialties Business Unit and member of the Executive Committee of Bayer MaterialScience, speaking at a press conference at the fair. “That’s why we strive to gain a deeper understanding of trends at all stages of the process chains. By doing this, we can invent exactly the products and technologies that help customers to position themselves and promote their profitable growth. This is at the very heart of our motto ‘Inventing for you’.”

New bio-based polyurethane products
Increasing numbers of consumers are opting for sustainable products. They pay particular attention to the use of renewable materials and environmental labels. Large suppliers of brand products are already supporting this trend.

At the European Coatings Show, Bayer MaterialScience is presenting the new hardener Desmodur® eco N 7300. Some 70 percent of its carbon content is based on biomass. Made of pentamethylene diisocyanate (PDI), this product achieves the high level of conventional, petrochemical-based isocyanates and is a perfect complement to polyols made from renewable raw materials, which are already being used in polyurethane coatings and adhesives.

With its new Impranil® eco product line, Bayer MaterialScience is also introducing the first bio-based polyurethane dispersions for textiles. The waterborne dispersions consist of up to 65 percent renewable raw materials.

Both new products help to improve the carbon footprint, and their raw materials base does not compete directly with food production.

Fast curing, brilliant look
A new car needs to look good and convey a sense of aesthetics and value. The clearcoat applied as the final coat is what gives vehicles their glossy appearance. Two-component polyurethane coatings have proved their worth in this field and are growing in popularity worldwide for metal bodywork and – at lower temperatures – plastic add-on parts. Until now, coatings on add-on parts took a long time to dry, however, and the susceptibility of the freshly cured surfaces to damage frequently led to problems during installation.

The new BLULOGIQ technology marks a milestone for Bayer MaterialScience, combining perfect appearance and rapid drying of the coating. At its heart is the thermolatent hardener Desmodur® blulogic 3190, which makes it possible to separate film formation and hardening.

More and more manufacturers are striving to build lighter cars so that consumers can save fuel and thus money. Thanks to the lower curing temperature of under 100 degrees Celsius, the BLULOGIQ technology can play a significant role in enabling plastics, composites and metals to be coated together in the medium term.

This creates promising opportunities for future lightweight concepts in mass production. Alternative energy sources, such as district heating, could then be used to heat the oven, thus making the overall process even more efficient.

Value-added food packaging
Many consumers focus on convenience when it comes to food shopping. They want lightweight products with packaging that can be opened and closed again easily without impacting on freshness. Flexible packaging is becoming increasingly popular for protecting foodstuffs, medicines and other products. At the same time, it needs to display all the required branding messages.

To meet these requirements, Bayer MaterialScience has developed Desmodur® quix 175, a new aliphatic isocyanate. Adhesives made using this material cure quickly at room temperature and improve productivity and flexibility for packaging manufacturers, who can react faster to trends and shorten delivery times significantly. The storage capacities previously required and the tied-up capital can now be used for other purposes, while investment in new facilities is not necessary.

Increased productivity with polyaspartics
When it comes to corrosion protection for steel structures and waterproof coatings for concrete flooring, exceptional performance and durability are an absolute must. At the same time, users face intense economic pressures. Curing must take place quickly with as few coats as possible in order to maximize throughput and minimize the interruption to usage.

Coatings based on polyaspartic raw materials from Bayer MaterialScience offer a particularly cost-effective solution. In contrast to conventional systems, this technology often requires fewer coating steps and curing is rapid. At the European Coatings Show, the company is introducing PASQUICK, the new umbrella brand for its polyaspartic technology. It represents the very pinnacle of raw materials expertise worldwide.

The latest development in the PASQUICK program is the new hardener Desmodur® E 2863 XP. Thanks to its very low viscosity, it can be used to produce flexible, solvent-free floor coatings. These are suitable for outdoor applications as well as interior applications such as odorless comfort flooring and sports flooring.

New tailor-made coating hardeners
The company also offers a wide range of isocyanate hardeners tailored for various properties of polyurethane coatings. One current challenge in the field of industrial coatings are low-viscosity, low-solvent waterborne coatings that do not require compromises when it comes to productivity and coating properties. With the introduction of Desmodur® XP 2840, Bayer MaterialScience now offers its customers the opportunity to position themselves with systems combining high performance and minimal solvent emissions.

Another new product is Desmodur® N 3580. In combination with conventional polyols, it is suitable for the formulation of auto refinish coatings, which offer a higher functionality and e.g. self-healing properties and a significantly improved adhesion – in addition to the high performance of conventional 2-component PU coatings.

All these customer-oriented developments from Bayer MaterialScience are based on precise analyses of the relevant market situations and reflect the mission statement “Inventing for you”.
