  • Cationic Curing - Sartomer

    2021-7-6 · Cationic curing is a photoinitiated, acid catalysed ring opening polymerisation of epoxy resins using onium salts. On exposure to UV light energy and in the presence of a hydrogen donor (typically the resin components of a formulation) cationic photoinitiators produce a long lived acidic species. This species ring opens an epoxy group to form a ...
