- Applications
RIASORB® UV 622 is a polymeric hindered amine light stabilizer (HALS) of N R type that protects polymers from degrada tion due to ultraviolet radiation and long term heat aging.. RIASORB ® UV 622 exhibits good compatibility in a wide range of polymers, very low volatility, low migration when using in cleaner surfaces, and excellent thermal stability at normal processing temperatures. RIASORB ® UV 622 has a low melting range that makes it effective for use in polyester, acrylic, PP, PE, elastomers, adhesives, and powder coatings. To optimize weathering performance in outdoor use, RIASORB ® UV 622 can be used in combination with phenolic & phosphite antioxidants, low molecular weight HALS, and UV absorbers. RIASORB ® UV 622 has antagonistic effect with thioether antioxidants such as DSTP or DLTP.
