Structure-property relationship study of UV-curable polyurethane dispersions

Ziniu Yu, BASF

Abstract:UV-curable waterborne resins are drawing more attention due to the combined advantages of UV-curable coatings and waterborne coatings, like easy to matte, monomer free, etc. Achieving good chemical resistance and physical drying from a waterborne UV coating, however, is always a challenge. In this paper, the physical performance of several UV-curable polyurethane dispersions will be discussed along with the structure-property relationship study.
