Applications

TINUVIN® 405 is designed to fulfill the high performance and durability requirements of acrylic powder coatings.

TINUVIN® 405 is recommended for applications such as:

• High performance automotive OEM powder coatings
• High performance industrial powder coatings

TINUVIN® 400 has been developed as an interaction-free UV absorber for use in amine and/or metal catalyzed coating systems and coatings applied on base-coats or substrates containing such catalysts.

TINUVIN® 400 is recommended for solventborne automotive OEM and refinish coating systems, UV cured coatings, and industrial coatings where long life performance is essential.

The protective effects of TINUVIN® 400 can be enhanced when used in combinations with a HALS such as TINUVIN® 123 or TINUVIN® 292. These combinations improve the durability of clear coats by retarding gloss reduction, delamination, cracking, and blistering.

The amount of TINUVIN® 400 required for optimum performance should be determined in trials covering a concentration range

Features and Benefits

• Excellent long term photo permanence
• Excellent thermal stability
• Non-migrating
• Ideal for glycidyl-methylacrylate-type (GMA) powder coatings due to low melting temperature
• Does not interact with amine- and/or metal-catalyzed
