Used primarily in and Plasticizers & Polymer applications, N,N’-Bis(2,2,6,6-tetramethyl-4-piperidyl)-N,N’-diformylhexamethylenediamine is specifically used in and stabilizer.
N,N’-Bis(2,2,6,6-tetramethyl-4-piperidyl)-N,N’-diformylhexamethylenediamine is a low molecular
weight hindered amine light stabilizer (HALS) that is commonly used as a thermal/light stabilizing
agent of polymeric materials at typical use concentrations of 0.5-0.8% (PubChem 2023). In the United
States, it is approved as a food contact substance at levels up to 0.25% when used as a UV stabilizer in
polystyrene, styrene block copolymers, acrylonitrile copolymers and resins, and polypropylene (U.S.
FDA 2023). No information on methods of manufacturing was found.
