    摘要: An adhesive composition for adhering two substrates includes a mixture of acrylate and epoxy with a tri- or tetrafunctional ketimine as a curing agent. The adhesive composition provides a two-stage cure in which, in a first stage, the adhesive is moisture cured at ambient temperature to provide green strength. In a second stage, the adhesive is post-cured at elevated temperatures to provide a high strength bond. The ketimine is formed form the reaction of diisopropyl ketone and an amine.
