Abstract

Polyurethane coatings are nowadays widely used in various coatings applications. This article describes polyurethane raw materials such as polyisocyanates, thermally activated polyurethanes, hydrophilic polyisocyanates, and polyurethane dispersions, which have been developed to meet market demands since polyurethane was invented by Otto Bayer in 1937. Today we are moving to a carbon neutral society and the paint industry is facing a challenge to shift from a linear to a circular economy. To ensure full circularity, sustainable polyurethane solutions for all four steps of the coatings life cycle are described.
