General description

Bis(2,2,6,6-tetramethyl-4-piperidyl) (T770) sebacate is a low molecular weight ultra violet (UV) hindered amine light stabilizer (HALS) made up of nitroxyl radicals. It acts as a heat controller that can react with phenolic antioxidants incorporated in polymers.[1][2][3]

Application

T770 can be used as a hindered amine UV stabilizer in plastic materials. It can be used in the manufacturing and packaging of pharmaceutical products.[4] Titanium oxide(TiO2)/T770 may be used in amine induced light stabilizers in the synthesis of recyclable water-based polyurethane with poly(oxytetramethylene)glycol (PTMG).[5]
