Light Stabilizer 622 Chemical name: Polymer of succinic acid and 4-hydroxy-2,2,6,6-tetramethyl-1-piperidinol 

Light Stabilizer 292 Chemical name: Bis(1,2,2,6,6-pentamethyl-4-piperidine)sebacate with 1-methyl- Mixture of 8-(1,2,2,6,6-pentamethyl-4-piperidine)sebacate 

UV absorber is benzotriazole mixture A:50%-52%(C2-H4-O)6-7-C19H21N3O3 b-[3-(2-H-benzotriazol-2-yl)-4-hydroxy-5-tert-butyl phenyl]-propionic acid polyethylene glycol 300 ester The UV absorber is a hydroxyphenylbenzotriazole type UV absorber, which can effectively protect the gloss of the coating, avoid cracks and spots, the product is easy to emulsify, and is especially suitable for water-based systems. Dispersion of UV absorbers in aqueous systems can be obtained by dissolving in water-soluble solvents such as diethylene glycol diethyl ether. UV absorbers with good high temperature resistance and anti-extraction properties are especially suitable for industrial and automotive coatings with high weather resistance requirements, and can also provide sufficient protection for sensitive substrates such as wood. UV absorbers are used with hindered amines (HALS), such as light stabilizers 292 or 123. These shared synergists can significantly improve coating performance and prevent gloss loss, cracking, blistering, peeling and discoloration.

UV Absorber 531 Chemical name:  2-hydroxy-4-n-octyloxybenzophenone   Molecular formula C21H26O3 Molecular weight 326 CAS number 1843-05-6 Product introduction:   UV absorber UV-531 is a highly efficient anti-aging additive with excellent performance, which can absorb 240-340 nanometer ultraviolet light, with light color, non-toxic, good compatibility, small migration, easy to process and so on.
