HXA UVA-622

Technical Datasheet | Supplied by The Hanson Group
4-Hydroxy-2,2,6,6-tetramethyl-1-piperidine-ethanol polymer with dimethyl succinate. It is a low-dust, polymeric hindered amine light stabilizer who provides outstanding light stability to many polymers and, in addition, gives long-term heat stability to polymers by radical trapping mechanism similar to that of hindered phenol. HXA UV-622 produces virtually no effect on initial substrate color. It is suitable for those applications which demand particularly high stability for such polymers as PP, HDPE, LDPE, LLDPE, ABS and PVC. It is FDA-cleared for use in food packaging applications including polyolefin and PVA with maximum concentration of 0.3%. In contrast to UV absorbers, HXA UV-622 effectiveness is independent of the polymer’s thickness. For this reason, HXA UV-622 is particularly effective in articles with high specific surface such as coating.
