Advantage and

Application

1. UV-1130 is a type of benzotriazole UV absorber which is widely used in coatings.
2. These combinations improve the durability of clear coats by inhibiting or retarding the occurrence of failures such as gloss reduction, cracking, color change, blistering and delamination.
3. The product is easy to emulsification, especially suitable for aqueous system.
4. It is suitable for industrial and automotive coatings. Beside, its broad UV absorption allows efficient protection of light sensitive base coats or substrates such as wood and plastics.
