ABSTRACT:
The disclosed method for applying an epoxy mortar is highly streamlined and involves little more than blending the curable epoxide binder for the mortar, adding aggregate and water to form the mortar, spreading the mortar on a surface, and curing the mortar in place on this surface. Flood coats, special trowelling techniques, and hydrophobic coatings for the aggregate particles are usually unnecessary. The simplification of the mortar-applying method depends upon formulating an epoxy binder material which includes a polyfunctional primary amine having an extremely low affinity for water, particularly a polynuclear cycloaliphatic polyamine such as methylene-bis-(4-cyclohexyl amine). A suitably formulated epoxy binder composition of this invention has a reasonably lengthy pot life, insensitivity to water, a relatively strong incompatibility with water (including the tendency to drive water out of a water/mortar emulsion so that the water forms a separate phase on the top surface of the mortar), good tensile and compressive strength after curing or hardening of the epoxy resin, a relatively low viscosity and easy spreadability during much of the pot life, and a high degree of lubricity with respect to metal trowels or other spreading tools.
