TINUVIN 479 is a hydroxyphenyl-triazine (HPT) UV absorber designed to fulfill the high performance and durability needs for automotive and industrial finishes. It has been developed as an interaction free UV absorber to be used in amine and / or metal catalyzed coating systems or in coatings applied on base coats containing such catalysts. Its high extinction coefficient allows the formulation of coatings with reduced UV absorber levels and / or thin film applications. Combinations especially with other HPT UV absorbers and the newest generation photoinitiators makes it an excellent choice for UV curing coatings.
