ABSTRACT:
A system comprising an epoxy resin and a particular type of amine curing agent makes possible a method of applying a coating to a wet or moist surface, even to a surface under water. These amine curing agents are substantially insoluble in water and are not water sensitive. The curing agents of this method are chosen from (1) amines of the formula: ##STR1## in which R is chosen from the group consisting of ether radicals of which one of the alkyl and alkylene radicals has at least eight carbon atoms or (2) a condensation product of a small proportion of a polyepoxide having a plurality of vic-epoxy groups and containing only members of the group consisting of carbon, hydrogen, oxygen and chlorine, and a larger proportion of a fatty amine of the formula: ##STR2## R.sub.2 denoting a radical chosen from the group consisting of alkyl radicals having at least eight carbon atoms and ether radicals of which one of the alkyl or alkylene radicals has at least eight carbon atoms. Preferably the adduct of amine and epoxy resin is used as the curing agent for the main part of the epoxy resin. In one mode of procedure, the epoxy resin and the amine-resin adduct are each made into an aqueous emulsion; the emulsions, when mixed, are useful for application to a damp or wet surface.
