A Novel Co-Polymerizable Benzotriazole UVA for Polyurethane Dispersion

摘要

Polyurethane dispersion (POD), has received more and more attention in coatings due to its water-borne nature and excellent overall properties. PUD's are also the top selection for exterior coatings applications in consideration of weathering sability. PUD's weathering stability can be further enhanced by adding Ultra Violet Absorbers (UVA) to the PUD to increase UV stability and provide long term durability.
