Applications
UV absorber 384-2 is a liquid benzotriazole UV absorber. Due to its liquid properties, 384-2 can be easily added to solvent-based systems and can also be used in specific water-based systems. It is particularly suitable for coatings that need to be exposed to high temperatures or extreme conditions for a long time, such as automotive paints and industrial paints. 384-2 works better when used in conjunction with hindered amine light stabilizers such as 292, which can improve the durability of the coating and delay discoloration, gloss reduction, cracking and delamination of the coating due to aging.
Storage
UV absorber 384-2 is stable in nature and has no special requirements; pay attention to moisture-proof and avoid high temperature.
Recommended Concentrations
0.05-0.3% (the specific amount to be added is subject to the actual application of the customer).
