Product details

UV-P
Chemical name : 2-(2'-Hydroxy-5'-methylphenyl)benzotriazole
Introduction : UV-P is a benzotriazole type ultraviolet light absorber (UVA), imparting good light stability for plastics and other organic polymers. UV-P protects polymers as well as organic pigments from UV radiation helping to preserve the original appearance and physical integrity of engineered plastics, elastomers, PVC, adhesives, and polyurethanes during outdoor weathering.
