> Excellent thermal stability and environmental durability, suitable for coatings used in extremely harsh conditions. Low migration, high concentration, and high efficiency. Good light stability, effective long life.

> Tinuvin 400 can be used in industrial paints and automotive paints with high performance and durability requirements (water-based, solvent-based and 100% solids are suitable). UV-400 is a UV absorber that does not cross-react with other components of the system and was developed specifically for amine-catalyzed or metal-catalyzed coating systems.

> The use of UV-400 in combination with hindered amine light stabilizers, such as HALS-292 or HALS-123, can significantly increase their effectiveness. This synergistic effect can reduce the gloss of the varnish, resulting in cracks, bubbles, delamination and discoloration. Good inhibition.
