UV-571 is ayellow transparent and viscous liquid benzotriazole UV absorber, which can givevarious polymers good photostability. It is easily dissolved in many solvents,monomers, or intermediates, and is easily emulsified in water-basedadhesives.UV-571 has good heat stability and compatibility of variouskinds of polymers,and high absorption and protection efficiency.
Widely used in thermoplasticPUR, coating and foam materials.
Also can be used for the rigid and plastic PVC,PVB, PMMA, PVDC, EVOH, EVA, heat curing unsaturated resin and PA, PET and PURcoil, and the PP fiber.
Applies to the emulsion, wax, adhesives andstyrene copolymer, elastomer and polyolefin.
