Stable aqueous coating dispersions, comprising a codispersion of at least a curable epoxy resin and a co-curable phenolic resin, and a combination of a non-ionic surfactant, comprising at least a reaction product of poly(ethylene oxide)polymer alcohols and a diglycidylether of a dihydric phenol having an epoxy group content in the range of from 1000 to 6000 mmol/kg, or a block copolymer of ethylene oxide and propylene oxide alcohol, and an anionic surfactant, comprising a random copolymer of at least one monovinyl arene, an alkyl acrylate, containing from 2 to 6 in the alkyl group, and acrylic acid, the copolymer having a weight average molecular weight in the range of from 3000 to 30.000, said composition partly neutralized by an amine to a neutralization degree of from 25 % to 95 %. |
