    • A blend of epoxy-amine adducts are useful as emulsifiers of aqueous epoxy resin dispersions comprises (A-1) one or more epoxy-amine adduct(s) obtained by the reaction of (i) one or more aromatic, cycloaliphatic or novolac epoxy compound(s) and (ii) one or more amine-terminated polyalkylene glycol(s) having a molecular weight of from 700-5000 and an ethyleneoxide content of at least 60% by weight in an equivalent ratio of amine-terminated polyalkylene glycol(s) to epoxy compound(s) of from 0.01:1 to 0.9:1; (A-2) one or more epoxy-amine adduct(s) derived from the reaction of (i) one or more aliphatic epoxy compound(s) and (ii) one or more amine-terminated polyalkylene glycol(s) having a molecular weight of from 700-5000 and an ethyleneoxide content of at least 60% by weight in an equivalent ratio of amine-terminated polyalkylene glycol(s) to epoxy compound(s) of from 0.01:1 to 0.9:1; (B-1) aromatic, cycloaliphatic or novolac polyglycidyl ethers; (B-2) optionally, polyglycidyl esters of aromatic or cycloaliphatic polycarboxylic acids; and (C) optionally, at least one of reactive thinners, pigments, filler or other addtitives.
