Product features and applications
1. UV-1130 is a benzotriazole ultraviolet absorber. This product has the characteristics of high temperature resistance and anti-extraction, and is suitable for industrial coatings and automotive paint fields that require weather resistance.
2. UV-1130 is easy to emulsify and is suitable for water-based systems.
3. UV-1130 has good synergy with hindered amine light stabilizer 292. It can make the coating have good performance and have a good inhibitory effect on the loss of gloss, cracks, blistering, peeling and discoloration of the coating.
Recommended dosage
2 parts of UV-1130 and 1 part of HALS-292 are used in combination. The total dosage is 1.5-4.5%, and the specific dosage is determined according to customer application testing.
