This product is a benzophenone UV absorber.
Ultraviolet absorbers are the most commonly used light stabilizers at present, which are a kind of ultraviolet light that can strongly and selectively absorb high-energy ultraviolet light, and perform energy conversion to release or consume energy in the form of heat energy or harmless low-energy radiation. substance.
Benzophenone containing an ortho-hydroxyl group only absorbs ultraviolet light below 380 nm and hardly absorbs visible light.
The product has strong absorption in the wavelength range of 270-380nm, and is suitable for polyvinyl chloride, acrylic resin, epoxy resin, phenolic resin, nitrocellulose and polyurethane. But the product can absorb part of the visible light, making the product slightly yellow.
