Applications

UV absorber 1130 is a universal liquid UV absorber. It has high thermal stability and high compatibility and is not easy to precipitate in the system. The liquid form of 1130 is convenient for processing and operation, and it is easy to emulsify and can be evenly dispersed in the water-based system. Based on the above characteristics, 1130 is widely used in the field of coatings, such as wood coatings, industrial coatings, automotive coatings, etc. When used with 292, 1130 can provide better protection for the coating, including preventing the coating from discoloring, losing gloss, cracking, and detaching from the substrate.

Storage

UV absorber 1130 is stable in nature and has no special requirements; pay attention to moisture-proof and avoid high temperature.

Recommended Concentrations

1.0%~3.0% (the specific amount to be added is subject to the actual application of the customer).
