Applications: This product is a highly effective light stability for variety of plastics and other organic substrates. Due to Its red shifted UV absorption, it is particularly suited foruse in the stabilization of polymers that are especially sensitive to long-wavelength UV radiation (eg. Polyurethanes, polyphenylene sulfide) and in certain applications where very low transmission of long-wavelength UV radiationis required (eg. Optical lenses). Its use is recommended in a variety of polymers and organic substrates, including a crylic polymers, unsaturated polyesters, polyvinyl-chloride, polyolefins, polyvinglbu-tyral, elastomers and adhesives.

Package: The package is the paperboard drum lined with plastic bag. The net weight is 20kg / drum

Storage: When stored, please avoid the rain, moisture and sunshine

Period of Validity:  About 2 years
