Abstract: EPOXY RESIN-AMINE SALT EMULSION COMPOSITION A unitary epoxy resin-amine salt emulsion composition has been developed in which the amine salt functions as both an emulsifying agent and a latent curing agent for the epoxy resin emulsion. This composition is used in combination with hydraulic cement which activates the amine salt to cure the composition. The epoxy resin-amine salt emulsion composition is stable when subjected to both freezing and elevated (120.degree.F) temperatures, and when combined with cement, it provides improved tensile and compressive strength compared to commercially available epoxy resin-cement systems.
