Purpose

4. Purpose

Used as UV absorber, derived from this product2-Hydroxy-4-Methoxybenzophenone (UV-9), 2-Hydroxy-4-n-Octyloxybenzophenone (UV-531) and other benzophenones, Such compounds as well as other monohydroxy, dihydroxy, trihydroxy, and tetrahydroxy compounds are the most widely used absorption light stabilizers. Can absorb290-400Nano ultraviolet light, and has good compatibility with most synthetic resins Capacitive, widely used in polymer materials. 2,4-Dihydroxybenzophenone is suitable for polyvinyl chloride, polystyrene, epoxy resin, cellulose resin, unsaturated polyester, coatings and synthetic rubber, etc. Maximum absorption wavelength range280-340Nano, general usage0.1-1%. However, the light stabilizing effect of this product is not outstanding.
