Sinepoxy®CA-HC1080 EL is a heat-initiated cationic curing agent based on blocked hexafluoroantimonate. It exhibits very fast initiation speed with cycloaliphatic epoxy resins and can also initiate the curing reaction of glycidyl ethers, glycidyl esters, etc. Compared with tertiary amine anionic initiators, formulations using this curing agent produce cured materials with lower shrinkage, better yellowing resistance, fuller and more glossy films.specifically suitable for replacing K-PURE® CXC-1612.
