2,4-Dihydroxybenzophenone, UV-0

It is a yellow crystalline powder, ultraviolet light absorber.

Used as ultraviolet absorber, 2-hydroxy-4-methoxybenzophenone (UV-9), 2-hydroxy-4-n-octoxybenzophenone (UV-531) derived from this product, etc. Benzophenones and other monohydroxy, dihydroxy, trihydroxy, and tetrahydroxy compounds are the most widely used absorption light stabilizers. It can absorb ultraviolet light of 290-400 nanometers and has good compatibility with most synthetic resins. It is widely used in polymer materials.

2,4-Dihydroxybenzophenone(UV-0) is suitable for polyvinyl chloride, polystyrene, epoxy resin, cellulose resin, unsaturated polyester, coatings and synthetic rubber. The maximum absorption wavelength range is 280-340 nanometers, and the general dosage is 0.1-1%. However, the light stabilizing effect of this product is not outstanding.
