There are disclosed herein water-dilutable reactive polyamide resins suitable for curing epoxy resins in aqueous systems. The polyamide resins are made by reacting together a C.sub.21 -cycloaliphatic dicarboxylic acid of the formula ##STR1## wherein x and y are integers from 3 to 9, x and y together equal 12, X is a member of the group consisting of H and COOH with one X of each moiety and a polyamine of the group diethylene triamine, triethylene tetramine and tetraethylene pentamine. These polyamide resins are soluble when water is added to the resin in amounts up to at least 45% by weight.
