    Abstract: Dual-curing is a processing technology based in the combination of two polymerization processes and the proper selection of the formulation. This methodology allows the preparation of intermediate materials with tailored characteristics, which can be viscous-liquids or rubbery solids according to their application. Once applied, the second stage is performed leading to a high crosslinked network. Usually, different monomers are involved, and unreacted monomer are still present in the intermediate material. This monomer experiments polymerization during the second step, but it can drip or be exuded during storage. In the present work, a commercial monomer, glycidyl methacrylate has been selected, because of the presence in the same molecule of an epoxide group, which can react with amines in the first stage of the dual-curing, and a methacrylate group that can be thermally or photochemically homopolymerized to complete the curing process. Diglycidylether of bisphenol A has been added to obtain a gelled intermediate material. The evolution of both curing steps has been studied by DSC and FTIR. The stability of the intermediate material has been confirmed and the characteristics of intermediate and final material have been evaluated by TGA and DMTA.
