Properties and Application:
UV Protection: UV-531 is primarily used as a UV absorber to protect materials from the damaging effects of UV radiation. It functions by absorbing UV light and converting it into less harmful energy, reducing the degradation and discoloration caused by UV exposure.
Application in Plastics: UV-531 is widely used in the plastics industry to protect polymers from UV-induced degradation. It is often incorporated into plastic formulations, such as polyethylene, polypropylene, and polystyrene, to extend the lifespan and maintain the appearance of plastic products exposed to sunlight.
Application in Coatings and Adhesives: UV-531 is also utilized in coatings and adhesives to prevent color fading, yellowing, and deterioration caused by UV radiation. It can be added to various coating systems, including paints, varnishes, and lacquers, as well as adhesive formulations to enhance their UV resistance.
Application in Personal Care Products: UV Absorber UV-531 may be found in some personal care products, including sunscreens, moisturizers, and cosmetics. Its UV absorption properties help protect the skin and hair from UV-induced damage, such as photoaging and color fading.
Storage Notes: Sealed stored in cold, dry, good ventilated place, avoid high temperature and moist.
