Technical Specifications

Industrial Applications

This UV absorber is extensively utilized in the stabilization of thermoplastic polyurethanes (PUR), paints, and foams. It demonstrates remarkable efficacy in rigid and flexible PVC, PVB, PMMA, PVDC, EVOH, EVA, and thermosetting unsaturated resins. Furthermore, it is suitable for polyamide (PA), polyethylene terephthalate (PET), PUR mesh, and polypropylene (PP) fibers. The product is also compatible with latex, waxes, adhesives, homogeneous polystyrene, its copolymers, elastomers, and polyolefins. In polyurethane systems, it can be used alone or synergistically with Light Stabilizer 292 to maximize durability.

Storage and Handling

UV Absorber 571 exhibits good storage stability under recommended conditions. To maintain optimal quality, avoid exposure to high temperatures and humidity during transportation and warehousing. The product should be stored in a cool, dry, and well-ventilated environment to prevent moisture absorption and heat accumulation. Standard industrial safety protocols apply when handling chemical additives. Packaging is available in 25KG plastic drums or 200KG iron drums to suit various logistical requirements. Our commitment to quality ensures every batch meets strict international standards for industrial chemical performance.
