Preparation and characterization of Several latent curing agents for epoxy acrylate resins

摘要

In this paper, novel latent curing agents for epoxy acrylic resin a～e were synthesized and characterized with 1H NMR and MS in this study. Pot life of epoxy acrylic resins containing 3wt.% a～e or γ-aminopropyltrithoxysilane was compared in this paper and experiment data indicated that a～e were inactive in epoxy acrylic resin at room temperature. Curing temperature for double compositions resin is about 120°C and pot life at room temperature is longer than 6 months. The optimal curing condition for these curing agents were selected through several experiments.
