| Use | Use of the product for the ultraviolet absorber, suitable for polyvinyl chloride, ABS resin, acrylic resin, polyurethane, melamine resin, cellulose resin and many other plastics. The product is benzophenone containing two Ortho hydroxyl groups, the strongest ability to absorb ultraviolet light, the wavelength of 330-370Nm ultraviolet light has a strong absorption effect, the disadvantage is also absorb part of the visible light, so that products slightly yellow. The compatibility of the product and the resin is good, the general dosage of 0.25-3%. In the paint also has good light stability effect. The oral administration of LD50 to rats was 10000mg/kg, which was not irritating to the skin and eyes. |
