Abstract:
A major change in coatings technology was caused by the restrictions on volatile organic compounds (VOC) in coatings. These government regulations combined with performance advantages were the key to the success of waterborne polyurethanes. The production and chemistry of waterborne one-component polyurethanes and reactive two-component systems are discussed. Examples for their application, predominantly in the field of surface coatings, are given.
