Tinuvin acts as a UV absorber in industrial products. It belongs to the class of hydroxyphenyl benzotriazoles, which provides good light stability to a wide variety of polymers. It offers strong absorption of ultraviolet radiation in the 300-400 nm region. It exhibits a high degree of photostability during prolonged exposure to light.
It provides ultraviolet protection on 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. Usage levels of Tinuvin range from 0,1% to 0,5%, depending on the substrate and performance requirements of the final application.
TINUVIN is a liquid hindered amine light stabilizer developed especially for coatings. It significantly extends the life of coatings by minimizing paint and varnish defects such as yellowing, cracking and loss of gloss.
