Trade Lead Description:
Chemical name: 2- (2'-Hydroxy-3'-tert-butyl-5'-methylphenyl) -5-chlorobenzortriazole
Introduction: UV-326 is a benzotriazole type ultraviolet light absorber (UVA), imparting good light stability for plastics and other organic polymers. UV-326 is especially suited for polyolefins and cold cured polyesters. It protects polymers from UV radiation helping to preserve the original appearance and physical integrity, especially for polyolefins and polyester resins.
