A unique portfolio of building blocks
Polyols yield high-quality polyurethane coatings
Reacting polyisocyanates and polyols creates polyurethane. As a leading supplier of building blocks for high-performance polyurethane coating systems, Covestro has a proven record of developing and innovating with polyurethane chemistry. Our extensive product portfolio provides important ingredients, such as polyester, polyether and polycarbonate polyols, for manufacturing high-quality polyurethane coating systems.
Our polyester and polyether polyols can be used for almost every property profile, and for formulating coating or adhesive systems that can be tailored to the requirements of the final product.
Developed in 1941, our Desmophen® polyether and polyester polyols in combination with Desmodur® crosslinkers are used to formulate one- (1K) and two-component (2K) polyurethane coating systems and high solids. Polycarbonate diols from our Desmophen® C series are used in combination with other polyols to adjust properties in 2K systems.
Polyurethane coating technology is used in a wide variety of applications, including:
- Automotive OEM finishes
- Transportation coatings
- Automotive refinishes
- Industrial coatings
- Plastic coatings
- Corrosion protection
- Wood and furniture finishes
- Structural protection
- Floor coatings
- Roof membranes
