Chemark UV-389 is a liquid UV absorber designed specifically for the protection of polymers from the damage of UV light. Chemark UV-389 is more solvent soluble, has better resin compatibility, is less volatile, and provides a degree of stabilization that is significant better than other UV absorber based on benzotriazole or benzophenone which are commercially available in the market

UV Absorber 400 is a kind of liquid hydroxyphenyl-triazine (HPT) UV absorber. It is with the characteristics of low color, low migration and high thermal stability. The product can fulfill the high performance and durability needs of waterborne, solventborne, and 100% solids automotive and industrial finishes.The product is mainly used in in amine and/or metal catalyzed coating systems and coatings applied on base-coats or substrates containing such catalysts. It is recommended for both solventbone and waterborne automotive OEM and refinish coating. It has good synergistic effect with HALS 292, HALS 123.

RIASORB ® UV 123 is a NOR type HALS (Hindered Amine Light Stabilizer) with low basicity. RIASORB ® UV 123 can effectively protects coatings from gloss reduction, cracking, blistering and delamination. Especially recommended for coatings containing aggressive media such as acids, catalyst residues. It is s uitable for high performance industrial coatings, automotive coatings. RIASORB ® UV 123 can be used in combinati on with UV absorber to obviously improve the weathering performance.

RICHVIN 1130 is a liquid type UV absorber of the benzotriazole with OH function group on the chemical structure which developed for coatings.
