The Hanson Group UV-770 acts as hindered amine light stabilizer. Bis(2,2,6,6,-tetramethyl-4-piperidinyl) decanedioate. It 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 hinder phenol. HXA UV-770 effectiveness is independent of the polymer’s thickness, in contrast to UV absorbers. It can be incorporated in monomer before polymerization, often with improvement of resin quality.
