UV ABSORBER refers to a kind of substances that can absorb the ultraviolet part of sunlight or fluorescence source without changing its own structure.
At present, the most idea UV absorber are complex, especially in Salicylate, Bnzophenone, Benzotriazole, instead of acrylonitrile, triazine match with Hindered Amine can get a more rational effect than any single UV absorber. The use areas of UV ABSORBER: polymers (plastics, etc.), coatings (automobile paint, building finish), printing inks, post-treatment of dyed/printed textiles, sunscreen cosmetics. UV ABSORBER can absorb UV strongly (especially the wavelength is 290-400nm).Good thermal stability, even in the process will not change because of heat, heat volatility is small; Good chemical stability, no adverse reaction with materials in the product; Good miscibility, can be evenly dispersed in the material, no spray frost, no leakage; The absorbent itself has good photochemical stability, does not decompose, does not change color; Colorless, non-toxic, odorless; Resistance to baptism; Cheap and easy to get; Insoluble or insoluble in water. The how many purposes depend on the size of market, so chemical industry is also competing for UV absorbers, with many bases in the four suburbs.
Our company has a large market in the sales of UV ABSORBER. In order to promote the ales market of our products, the "ultraviolet absorber column" is hereby launched.

FEATURE AND APPLICATIONJADEWIN UV312 is an ultraviolet light absorber of the oxanilide class, which imparts outstanding light stability to plastics and other organic substrates. Particularly it is recommended for rigid and flexible PVC and polyesters.Depending on the application, the typical addition level of JADEWIN UV 312 is between 0.1 and 1%.The product has good synergistic effect with hindered amine series light stabilizer and benzoate ultraviolet absorbent. In the coating industry, the addition amount of JADEWIN UV 312 is 0.5%-3.5% and the blocking amine series light stabilizer is 0.5-2% (for example, JADEWIN LS 292 is used for solvent coatings, and JADEWIN LS119 is used for powder coatings), the addition amount is based on the resin solid weight percentage. Appropriate tests shall be conducted to determine the appropriateness of additions for a particular purpose.APPLICATION:It has excellent light stabilization effect in the application of plastic coatings.It has better color protection, even in alkaline and metal catalyst environment, the product has a better effect than traditional ultraviolet absorbent.It is low volatile and has excellent compatibility of polar plastics and coatings.It absorbs at low wavelengths, it can be combined with optical brighteners, no cross influence.
