Abstract

A two-component, or two-part epoxy resin composition which adheres well to wet mortar and concrete is provided. One part comprising a non-cycloaliphatic epoxy resin, a reactive diluent in the form of an epoxy compound, a modifying resin selected from the group consisting of a coumarone-indene polymer resin, a dicyclopentadiene polymer resin, an acrylonitrile modified polyvinyl chloride resin, an amino terminated acrylonitrile-butadiene copolymer resin, and an epoxy terminated polybutadiene resin, a silane coupling agent having an epoxy or amino group, and a synthetic zeolite is combined, on use, with the other part comprising an amine curing agent selected from the group consisting of a cycloaliphatic polyamine, an aliphatic/aromatic polyamide, and an amine adduct.
