Usage

Description

UV-384-2 is a liquid UV absorber of benzotriazole type used for coatings. Its very high thermal stability and environmental permanence make it suitable for coatings exposed to high bake cycles and/or extreme environmental conditions. Its high performance and durability meet requirements of automotive and industrial high quality finishes. Its broad UV absorption allows efficient protection of light sensitive base coats or substrates suchj as wood and plastics.

Physical properties

Tinuvin 384-2 shows high thermal stability and high compatibility in various polymers. It is especially suitable for industrial and automotive coatings such as coil coating, wood coating, etc.

Application

It is of the high thermal stability and high compatibility in various polymers. It is especially suitable for industrial and automotive coatings. 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 costs by inhibiting or retarding the occurrence of failures such as gloss reduction, cracking, color change, blistering and elamination. The amount of UV-384-2 required for optimum performance should be determined in trials covering a concentration range.
