Application
*TRUELICHT 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
*TRUELICHT 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
*TRUELICHT UV P has a high degree of photostability over long periods of light exposure.
* TRUELICHT UV P can be used in combination with phenolic & phosphite antioxidants, and HALS to optimize performance in outdoor use.
