Synonym: Dimethyl succinate polymer with
4-hydroxy-2,2,6,6-tetramethyl-1-piperidine ethanol
PowerStab™ 622 is a polymeric hindered amine light stabilizer (HALS) which is effective in a broad range of polymers and applications. It is non-discoloring, low volatility and excellent resistance to migration, low basicity for reduced interactions with pigments and other stabilizers, and extensive food contact clearances.
