HMBTAD (2,2,6,6-Tetramethylpiperin-4-yl)-hexane-1,6-diamine

HMBTAD is a key hindered amine intermediate used in the production of high-molecular-weight hindered amine light stabilizers (HALS). Its bifunctional diamine structure makes it an important building block for the synthesis of triazine-based polymeric HALS, including HALS 944-type products and other related light stabilizers. As a key upstream intermediate in the HALS value chain, HMBTAD is particularly important for manufacturers requiring consistent quality and reliable downstream polymerization performance.
