2,2′-Dihydroxy-4,4′-dimethoxybenzophenoneusage
1. This product is a benzophenone UV absorber.
2. Ultraviolet absorbers are currently the most commonly used light stabilizers. These are a class of ultraviolet light that can strongly and selectively absorb high energy and perform energy conversion to release energy in the form of heat or harmless low-energy radiation. Or the substance consumed.
3. This product contains a vicinal hydroxyl group of benzophenone which absorbs only 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.
4. However, the product can absorb a part of visible light, making the product slightly yellow. The oral LD50 of the rats was 3000 mg/kg.
