Introduction of UV-0

Light yellow needle crystal or white powder. Melting point 142.6-144.6 ° C. 25 ° C solubility (g / 100 ml solvent): acetone > 50, benzene 1, ethanol > 50 water < 0.5, n-heptane < 0.5.

Application Of UV-0

• Use as UV absorber, 2-hydroxy-4-methoxybenzophenone (UV-9), 2-hydroxy-4-n-octyloxybenzophenone (UV-531) derived from this product. Such benzophenones, as well as other monohydroxy, bishydroxy, trihydroxy, and tetrahydroxy compounds, are the most widely used absorption light stabilizers. It can absorb 290-400 nm UV light and has good compatibility with most synthetic resins. It is widely used in polymer materials. 2,4-Dihydroxybenzophenone is suitable for polyvinyl chloride, polystyrene, epoxy resins, cellulose resins, unsaturated polyesters, coatings and synthetic rubbers. The maximum absorption wavelength range is 280-340 nm, and the general dosage is 0.1-1%. However, the light stabilizing effect of this product is not outstanding. This product has an oral LD50 ash of 8600 mg/kg for rats and 2336 mg/kg for mice.
   

• Uses for polyolefins, polyvinyl chloride, polystyrene, etc.
   

• Use It is mainly used as a light stabilizer for plastics. It can effectively protect organic glass and fabrics, prevent data from being deteriorated by light, and is also used as an intermediate for synthesizing other UV absorbers.
