Advantage and

Application

It is of the high thermal stability and high compatibility in various polymers. It is especially suitable for industrial and automotive coatings such as coil coating, wood coating. UV-384-2 can be enhanced when used in combination with a HALS stabilizer such as UV-292 or UV-123. 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 extinction.
