APPLICATIONS
5327 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.
