Abstract
A simple and robust strategy to generate time-temperature-transformation (TTT) diagrams for dual-curable thermosets is presented. TTT diagram is built for a dual-curable amine-epoxy formulation. Both curing stages are epoxy-amine polycondensations. Whereas the first stage is carried out at relatively low temperature using a strongly nucleophilic aliphatic amine, the second is carried out at high temperature with a weakly nucleophilic aromatic amine. The good separation between curing stages enab...
