INVENTINGVISIONS FOR YOU

04 DispersionsAs your leading partner for polyurethane chemistry, we know you are competing in increasingly challenging environments: Your customers are becoming more and more demanding in their expectations for quality, dura-bility, sustainability and aesthetics of products. And they have more choices. For you this means that cost pressure is rising – while innovation cycles are becoming faster and faster.

Helping you to turn this challenge into your competitive advantage is the goal that drives our daily work. We call it: INVENTING FOR YOU. But what exactly are the basic values underlying this promise? What principles enable us to improve your productivity, drive sustainability, ensure reliability and co-create future-proof businesses? First and foremost, we are curious. Because only if we listen closely to you and ask the right questions, we can respond to your individual needs with new, creative and unexpected solutions that make a real difference to you. That’s why inventing for us always starts with thinking about your unmet business challenges. It requires an indepth understanding of your needs along the whole value chain. To make sure: What we invent stands the test of time. Living up to this aspiration requires more than competencies – it calls for a corporate culture of being courageous. A culture that is defined and lived by dedicated people who cooperate to push the boundaries of invention founded on knowledge and experience. Our courage permeates our entire business – from partnerships to business models. This is also reflected in our colorful business philosophy. We appreciate partnerships that go beyond traditional black-and-white ways of acting and thinking. An attitude of open-ness that invites you to co-create new things – rather enabling you than just providing. We are optimistic and resourceful in finding solutions that inspire our customers and partners.

This set of fundamental values adds up to an unrivaled performance orien-tation to constantly strive for the better, be it through big or small changes. A true sense of business regardless of function. And a deep commitment to delivering our promise everyday. Anywhere. Again and again.

INVENTING FOR YOU.

Pioneering polyurethane chemistryEver since the discovery by Otto Bayer of the po-lyisocyanate polyaddition process in 1937, Bayer – now Covestro – has pioneered polyurethane chemistry. 50 years ago, Bayer – now Covestro – developed the first applications using polyiso-cyanates for the coatings and adhesives sectors. We work closely with our customers to systemati-cally advance the state of the art in polyurethane technology. Using market-oriented research and development, we specifically adapt our product portfolio to our customers’ increasingly stringent requirements. Together with you, we want to con-tinue our successful journey along this path.

High-performance waterborne portfolioAs one of the leading producers of coating and adhesive raw materials, we offer a comprehensive range of high-grade raw materials for polyurethane coatings and adhesives. The demand for ecological technology is steadily growing and has greatly accelerated the shift away from solvent-borne coatings and adhesives to solvent-free and waterborne systems. With our ecological techno-logy platform we offer a wide variety of aqueous dispersions for the coatings and adhesives mar-ket. Our mission is to provide competitive advan-tages for our customers: eco-friendly products with superior quality and performance to enable highly efficient coating and bonding proces-ses. We are continuously developing innovative dispersions to complement our range of water-borne products based on a variety of chemis-tries – polyurethane, polyacrylate, and polyester dispersions. Depending on your requirements and cost-performance demands, we can offer the most attractive formulation option based on a 1K or 2K system.

Main application areasThe most important areas of application for our waterborne coating raw materials are wood and furniture coatings, metal and plastic coatings for industrial applications, high-grade floor coatings, automotive OEMs, transportation vehicle and refinishing coatings and textile coatings. More- over, we offer specialty products for glass fiber sizes and applications in the paper and printing ink industries.

As a fast-growing and highly promising segment for waterborne coatings technology, UV-curing polyurethane dispersions combine fast curing with excellent coating properties. Firmly established in wood coatings and growing in plastics coatings, we are continuously extending our range to include additional applications.

Our waterborne adhesive raw materials are first choice in heat-activated bonding applications from 3-D film lamination in the furniture industry and heat lamination for car interior trims to bond-ing footwear. Besides the classical foam bonding market, more and more applications are now emerging for our waterborne contact adhesives.

Why not check out our waterborne product lines: Bayhydrol® and Bayhytherm® for coating applica-tions, Dispercoll® for adhesives applications, Impranil® for textile applications, and Baybond® for glass fiber sizes. In combination with our polyisocyanate crosslinkers Desmodur® and Bayhydur® we offer superior system solutions for 2K or 1K stoving applications.

SolutionstoenhanceyourprocessefficiencyNowadays, the quality demands made on indust-rial processes are very high. But at the same time, there is a clear need to cut costs. Both goals can be achieved by increasing process efficiency. The complexity of the processes involved in manufac-turing coatings and adhesives offers us various opportunities to enhance process efficiency. Significant process-optimizing and cost-cutting gains are possible, for example through faster curing and shorter process times. At Covestro we have a wide range of solutions designed to enhance your process efficiency. Why not take advantage of our know-how? These solutions will be good for your bottom line.

Outstandingqualityandsupplysecurity–worldwideCovestro, the world’s leading manufacturer of aliphatic and aromatic isocyanates, offers an extensive range of raw materials and services for manufacturers of coatings and adhesives. This allows the very latest technology to be used extremely effectively for a variety of applications. Thanks to its unique setup and worldwide network of state-of-the-art production sites, R&D facilities and customer technical centers, industry-leading supply chain setup, global orientation and local stocks, extremely large product portfolio, highest

health, safety and environmental (HSE) standards, as well as tailored supply chain flexibility with short lead times, Covestro offers the industry unrivaled supply security and assured quality.

Highperformance–enabledbynatureSustainability drives innovation at Covestro. We are committed to optimizing our manufacturing processes, reducing the impact of logistics, and enabling sustainability along the value chains. Renewable feedstocks offer opportunities for developing more sustainable building blocks for coatings and adhesives – with significant po- tential for reducing the carbon footprint of end products while also reducing our overall depend- ence on fossil-based resources. But to make more sustainable solutions not just possible but also economically feasible, the performance of all our feedstocks needs to satisfy high industry standards. To this end, we are evaluating the use of renewable raw materials and will enlarge our product portfolio with new bio-based and mid- to long-term cost-competitive products, provided the raw materials become commercially available. In all these efforts we are committed to focusing on products that perform at least as well as established products but are at the same time more sustainable.
