Application
UV-absorbing agent UV-531 is an excellent anti-aging additive with excellent performance.
It can absorb 240-340 nm UV light, it has the characteristics of light color, non-toxicity, good compatibility, low mobility and easy processing.
It provides maximum protection for the polymer and helps to reduce color while retarding yellowing and retarding physical property loss.
It is widely used in PE, PVC, PP, PS, PC, plexiglass, polypropylene fiber and ethylene vinyl acetate.
It also provides good light stability for dry phenolic and alkyd varnishes, polyurethanes, acrylics, epoxies and other air drying products, as well as automotive finishing paints, powder coatings, polyurethanes, and rubber products. The dosage is 0.1%-0.5%.
