Applications

HS-123 is a liquid hindered amine light stabilizer with NOR structure. 123 can significantly improve the weather resistance of coatings and has a good inhibitory effect on gloss loss, cracking, blistering, peeling and discoloration. HS-123 has low alkalinity and is especially suitable for systems containing acidic substances, catalyst residues and other special factors. Commonly used in high-performance coating systems, such as high-performance industrial coatings, automotive coatings, etc. 123 is often used in conjunction with UV absorbers to achieve better weather resistance.

Storage

HS-123 is stable in nature and has no special requirements; pay attention to moisture-proof and avoid high temperature.

Recommended Concentrations

0.05-1.0% (the specific amount to be added is subject to the actual application of the customer).
