FEATURE AND APPLICATION

UV -P is an ultraviolet absorber (UVA) of the hydroxyphenyl benzotriazole

class,imparting good light stability to a wide variety of polymers,with strong absorption of ultraviolet radiation in the 290-400 nm region

UV -P provides ultraviolet protection in a wide variety of polymers including styrene homo- and copolymers, engineering plastics such as polyesters and acrylic resins, polyvinyl chloride, and other halogen containing polymers and copolymers (e.g. vinylidenes), acetals and cellulose esters. Elastomers , adhesives, polycarbonate blends, polyurethanes, and some cellulose esters and epoxy materials

UV -P has a high degree of photostability over long periods of light exposure.

UV -P can be used in combination with phenolic & phosphite antioxidants, and HALS to optimize performance in outdoor use.
