CHEMK UV-1130 is a liquit UV absorber of the hydroxyphenyl-benzotriazole class specifically developed for coatings, the product is miscible with all common solvents but also easily incorporated into water borne systems. In view of the high durability demands, its high temperature and extraction resistance makes it especially suitable for industrial and automotive coatings. Because of its broad UV absorption, UV-1130 also provides efficient protection to light sensitive substrates such as wood and plastics.

CHEMK UV-1130 may be used in combination with a light stabilizer of the sterically hindered amine class (HALS) such as LS-144, LS-292, LS-123. These synergistic combinations impart superior coating protection against gloss reduction, cracking, blistering, delamination and color change. The light stabilizers may be added in two coat automotive finishes to the clear coat and to the base coat. However, according to our experience, the optimum protection is achieved by adding the light stabilizer to the topcoat.

CHEMK UV-1130 is recommended for both solvent and water based coating such as: 

● Automotive coatings

●Industrial coatings

● Wood coatings

● Plastics and urethane coatings
