DispersionsEfficiency meets sustainability.Solutions to enhance your process efficiencyNowadays, the quality standards made on industrial processes are veryhigh. This is equally true of the cost-cutting requirements. However, bothgoals can be achieved by increasing process efficiency. At Covestro,we have a wide range of solutions designed to enhance your processefficiency. Why not take advantage of our know-how? These solutionswill benefit your bottom line.SustainabilitySustainability is at the heart of the Covestro strategy. We inspire innovationand drive growth through profitable products and technologies that benefitsociety and reduce the impact on the environment.Our coatings, adhesives and specialty products and solutions contributeto sustainability through: Saving energy – fast and smartPolyurethane systems represent a benchmark in productivity andprocess efficiency in many industries. We strive to further push thelimits of efficiency by developing game-changing new solutions. Reducing wasteWe offer solutions such as innovative 1K technologies that enable our value chain partnersto use materials more efficiently and reduce waste. Cutting emissionsBayhydur and Desmodur grades are key enablers for low-emission solutions in thecoatings and adhesives industries – waterborne and high solids/100% solids! Responsible management of natural resourcesHighly durable PU-based coatings and adhesives significantly extend the lifetime ofa coated product and thus help to prolong resource use.

DispersionsAqueous dispersions –an innovative andeco-friendly platform.Pioneering polyurethane chemistryEver since Otto Bayer’s discovery of the polyisocyanate polyadditionprocess in 1937, Bayer – now Covestro – has pioneered polyurethanechemistry. 70 years ago, Bayer – now Covestro – developed the firstapplications using polyisocyanates for the coatings and adhesivessectors. We work closely with our customers to systematically advancethe state of the art in polyurethane technology. Using market- orientedresearch and development, we specifically adapt our product portfolioto our customers’ increasingly stringent requirements. Together withyou, we want to continue 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 poly urethanecoatings and adhesives. The demand for sustainable technology is steadilygrowing and has greatly accelerated the shift away from solvent-bornecoatings and adhesives to 100% solids and waterborne systems. With ourecological technology platform we offer a wide variety o f aqueousdispersions for the coatings and adhesives market. Our mission is toprovide competitive advantages for our customers: eco-friendly products with superior quality and performance to enable highly efficientcoating and bonding processes. We are continuously developing innova-tive dispersions to complement our range of waterborne products basedon a variety of chemistries – polyurethane, polyacrylate and polyester7

dispersions. Depending on your requirements and cost-performancedemands, we can offer the most attractive formulation option based ona 1K or 2K system.Main application areasThe most important areas of application for our waterborne coating rawmaterials are wood and furniture coatings, metal and plastic coatingsfor industrial applications, high-grade floor coatings, automotive OEMs,transportation vehicles and refinishing coatings and textile coatings.More over, we offer specialty products for fiber sizings and applications inthe paper and printing ink industries.As a fast-growing and highly promising segment for waterborne coatingstechnology, UV-curing polyurethane dispersions combine fast curing with excellent coating properties. Firmly established in wood coatingsand growing in plastics coatings, we are continuously extending ourrange to include additional applications.Our waterborne adhesive raw materials are first choice in heat-activatedbonding applications from 3-D film lamination in the furniture industryand heat lamination for car interior trims to bonding footwear. Besidesthe classical foam bonding market, more and more applications are nowemerging for our waterborne contact adhesives.Please check out our waterborne product lines: Bayhydrol and B ayhytherm for coating applications, Dispercoll for adhesivesapplications, Impranil for textile applications and Baybond forfiber sizings. In combination with our polyisocyanate crosslinkersDesmodur and Bayhydur we offer superior system solutions for2K or 1K stoving applications.
