Light yellow crystals. Melting point 139-140 °C. Soluble in ethyl acetate, methyl ethyl ketone and toluene, do not dissolve in water.
The goods is benzophenone UV absorbers. UV absorbers are currently the most widely used light stabilizers, which are able to strongly and selectively absorb high-energy ultraviolet light, and the energy conversion to the form of heat or harmless low-energy radiation to the energy release or consumption Of the substance. Benzophenone containing an ortho-hydroxy group absorbs only ultraviolet light of 380 nm or less and hardly absorbs visible light. The goods in the 270-380nm wavelength range has a strong absorption, for PVC, acrylic resin, epoxy resin, phenolic resin, nitrocellulose and polyurethane. But the product can absorb part of the visible light, so that products with yellow.
Storage: Storage should be cool and ventilated, away from heat, fire, to prevent sun exposure, heat is strictly prohibited.
