TINUVIN 327 is an ultraviolet light absorber of the hydroxyphenyl benzotriazole class, which imparts outstanding light stability to plastics and other organic substrates.
The UV absorbance of the product is red-shifted relative to conventional benzotriazole UV absorbers, i. e. it exhibits enhanced absorption of long-wavelength UV radiation (>350 micromater).
TI NUVI N 327 is a highly effective light stabilizer for a variety of plastics and other organic substrates.
Due to its red-shifted UV absorption, it is particularly suited for use in the stabilization of polymers that are especially sensitive to long-wavelength UV radiation (e. g. polyurethanes, polyphenylene sulfide) and in certain applications where very low transmission of long wavelength UV radiation is required (e. g. optical lenses).
Its use is recommended in a variety of polymers and organic substrates, including acrylic polymers, polycarbonate, polyesters, styrene homo- and copolymers, unsaturated polyesters, polyvinylchloride, polyolefins, polyvinyl butyral , elastomers, and adhesives. |
