Chemical name：2-hydroxy-4-n-octyloxy Benzophenone

Molecular formula：C₂₁H₂₆O₃

molecular weight：315.8

CAS：1843-05-6

Structural formula：

Basic characteristics：UV absorber chemsorb-531 is a high-efficiency anti-aging additive with excellent performance, which can absorb UV light of 240-340 nm. It has the characteristics of light color, non-toxic, good compatibility, small mobility, easy processing and so on. It has the greatest protective effect on the polymer, and helps to reduce the color, while delaying yellowing and blocking the loss of physical properties. It is widely used in PE, PVC, PP, PS, PC, plexiglass, polypropylene fiber, vinyl acetate, vinyl ester, etc., and provides good light stability for dry phenolic and alkyd varnishes, polyurethane, acrylic, epoxy and other air drying products, as well as automotive refinishing paint, powder coating, polyurethane, rubber products, etc. Dosage: 0.1-0.5%.

physical property：

Chemsorb-531 has strong absorption characteristics in the range of UV wavelength 240-340nm, and there is almost no absorption in the visible region. Strong absorption peaks appeared at the ultraviolet light with wavelengths of 290nm and 330nm,

Packaging and storage：This product is non-toxic, non flammable, non explosive, non corrosive, and has good storage stability. It is packed in cardboard barrels lined with plastic bags, with a net weight of 25kg/ barrel. It can also be designed according to customer requirements.
