Tinuvin® P

Technical Datasheet | Supplied by BASF
Tinuvin® P by BASF is phenol, 2-(2H-benzotriazol-2-yl)-4-methyl grade. Acts as a UV absorber. It belongs to hydroxyphenyl benzotriazole class, imparting good light stability to a wide variety of polymers. Offers strong absorption of ultraviolet radiation in 300-400 nm region. Exhibits high degree of photostability over long periods of light exposure. 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. Also suitable for polycarbonate blends, polyurethanes, and epoxy materials. Use levels of Tinuvin® P ranges between 0.1% and 0.5%, depending on substrate and performance requirements of the final application.
