Applications

HS-622 is a low-alkalinity polymeric hindered amine light stabilizer that can protect polymer materials from light and heat degradation caused by ultraviolet light and long-term heat aging. HS-622 has good compatibility with polymer materials, low volatility, migration resistance, and the products will not spray frost. 622 has excellent thermal stability at processing temperature. 622 has a low melting point and can be used in materials such as polyester resins, acrylic resins, PP, PE, elastomers, adhesives, and powder coatings. HS-622 has little interaction with pigments and can be used in combination with phenolic and phosphite antioxidants, low molecular weight HALS and ultraviolet absorbers to improve the stability of outdoor products. HS-622 is not recommended for use in combination with sulfur-containing antioxidants DLTP and DSTP.

Storage

HS-622 is stable in nature and has no special requirements; pay attention to moisture-proof and avoid high temperature.

Recommended Concentrations

0.1-0.5% (the specific amount to be added is subject to the actual application of the customer).
