Abstract
This invention relates to compositions useful as adhesives and more particularly to the preparation of heat-curable epoxy-based adhesive compositions that are resistant to being washed off substrate surfaces prior to being cured. The incorporation of a solid diene-based rubber, in particular an acrylonitrile-butadiene copolymer rubber having a relatively high Mooney viscosity, significantly enhances the wash-off resistance of the adhesive, while still allowing the adhesive to be readily dispensed by pumping under high shear conditions.
