One-component epoxy resin with imine as water-initiated latent hardener: Improvement of the mechanical and adhesive properties by the addition of methacrylate copolymer

摘要

The effect of addition of methacrylate polymer into a one-component epoxy resin, containing Epikote 828 and diimine as a water-initiated hardener, was examined. Although the cured epoxy resin in the presence of methyl methacrylate-butyl acrylate (MMA-BA) copolymer was very brittle, the resin containing MMA-BA-[gamma-(methacryloxy)propyl]trimethoxysilane (TMSMA) copolymer showed good mechanical and adhesive properties. The adhesive strength of the cured epoxy resin containing MMABA-TMSMA copolymer was much higher than that without its polymer. (c) 2005 Wiley Periodicals, Inc.
