TINUVIN® 400 a liquid hydroxyphenyl-triazine (HPT) UV absorber designed to fulfill the high performance and durability of solvent-borne, and 100% solids automotive and industrial finishes. Its low colour and stability make it an excellent choice for all coatings where low color characteristics are ideal for use in combination with the newest generation photoinitiators to provide durable UV clear coats.

TINUVIN 400 provides excellent performance in coatings due to:

• very high thermal stability and performance for coatings exposed to high bake cycles and/or extreme environmental conditions
• hydroxy functionality to minimize migration
• high photo-stability for long life performance
• high concentration for maximum efficiency

This material 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. It is recommended for solvent-borne automotive OEM and refinish coating systems, UV cured coatings, and industrial coatings where long life performance is essential.

Features & Benefits

• Hydroxyphenyl-triazine with high absorbance in the UV-B region
