TINUVIN® 384-2 is a liquid UV absorber of the hydroxyphenylbenzotriazole class developed for coatings. Its very high thermal stability and environmental permanence makes it suitable for coatings exposed to high bake cycles and/or extreme environmental conditions. It has been designed to fulfill the high performance and durability requirements of automotive and industrial high quality finishes. Its broad UV absorption allows efficient protection of light sensitive base coats or substrates such as wood and plastics.

Applications

TINUVIN® 384-2 is recommended for:

• Automotive coatings
• General industrial applications i.e. coil coatings, wood coatings.

The liquid form of TINUVIN® 384-2 provides easy incorporation into solvent borne systems.
The performance provided by TINUVIN® 384-2 can be enhanced when used in combination with a HALS stabilizer such as TINUVIN® 292 or TINUVIN® 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 delamination. The amount of TINUVIN® 384-2 required for optimum performance should be determined in trials covering a concentration range.

Features and Benefits

• Versatile hydroxyphenyl-benzotriazole UVA for use solvent based coatings
