Applications

• RIASORB® UV 384-2 is a liquid benzotriazole UV absorber, which is convenient for solvent-borne and specific waterborne coatings. Recommend for coatings expose to high thermal and extreme environmental condition, like high-performance industrial coating, automotive coating.
• The performance of RIASORB® UV 384-2 can be enhanced when used in combination with HALS stabilizer such as RIASORB® UV 292. These combinations improve the durability of coatings by inhibiting or retarding failures like discoloration, gloss reduction, cracking, and delamination.
