ABSTRACT:
A system comprising an epoxy resin and a particular type of amine curing agent makes it possible to apply 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 amines which are used in this coating as a curing agent (in the form of a reaction product with a smaller amount of an epoxy resin to make an amine adduct) are of the formula: ##EQU1## in which R is chosen from the group consisting of alkyl radicals having at least eight carbon atoms, and alkyl ether radicals of which one of the alkyl radicals has at least eight carbon atoms. The adduct of amine and epoxy resin is used as the curing agent for the main part of the epoxy resin.
