UV Absorber 400 application:

Excellent thermal stability and environmental durability, suitable for coatings used in high-temperature baking and extreme harsh conditions.

Low migration effect, high concentration and high efficiency.

Good light stability and long effective life.

UV-400 can be used for industrial paints and automotive paints with high performance and durability requirements (applicable to water-based, solvent-based and 100% solid conditions).

UV-400 is a UV absorber that has no cross-reaction with other components in the system and is specially developed for amine-catalyzed or metal-catalyzed curing coating systems.

If UV-400 is used in combination with hindered amine light stabilizers such as UV-292 or UV-123, its performance can be significantly improved. This synergistic effect has a good inhibitory effect on the reduction of gloss, cracking, bubbles, delamination and discoloration of varnish.
