An ideal UV/light stabilizer for compound, particularly to salicylic acid phenyl ester, ketone, benzo-triazole class, replacing acrylonitrile, triazine and hindered amine compound, can be made more rational than any individual UV absorber effect. UV absorber using areas: polymers (plastics), paints (automotive paint and finishing of buildings), printing inks, dyeing or printing textiles of post-processing, sunscreen products.

Ultraviolet absorbent UV-absorber UV-531 share with you should have the condition:

① can strongly to absorption UV (especially wavelength for 290-400nm); II hot stability good, even in processing in the also does not due to hot and changes, hot volatile sex small; ③ chemical stability good, not and products in the material component occurred adverse reaction; II mixed dissolved sex good, can uniform to dispersed in material in the, not spray cream, not seeping; ⑤ absorption agent itself of light chemical stability good, not decomposition, not discoloration; ⑥ colorless, and nontoxic, and no smelly; sadly resistance dip wash; ⑧ price low, and easy have,; 9. not dissolved, or difficult dissolved Yu water.

Chemical structure of UV absorbers can be divided into the following categories: salicylic acid phenyl ester, ketone, benzo-triazole class, triazine, replacing acrylonitrile and hindered amine.

Long Yu, Zhangjiagang chemical company in the production process, the adoption of strict management mode, from raw materials, formulation, process control and other layers of checks, ensure quality of product quality, particularly on the crystallization of the product, the use of advanced equipment and process control of crystallization, and appearance of the product meets the requirements of a yellowish needle Crystal, and quality by customers at home and abroad alike.
