An aqueous epoxy resin system AB is described comprising an aqueously dispersed epoxy resin A having, on the average, at least one epoxy group per molecule, and a water-soluble or water-dispersible curing agent B which comprises the reaction product of an amine B1 having at least one primary and/or at least one secondary amino group, an adduct B2 of a polyalkylene ether polyol B21 and an epoxide component B22, and an aromatic compound B3 having at least one acidic group selected from the group consisting of hydroxyl and carboxyl groups, which system can be applied by rolling, spraying or brushing to provide corrosion protection on base metals.

Water-borne paints based on epoxy resins

Water dilutable amine curing agents for aqueous epoxy resin dispersions, comprising a combination of an epoxide-amine adduct with an emulsifier, the epoxide-amine adduct being obtainable by reacting a polyepoxide with a reaction product of an amine and an epoxide component or an amine and subsequent reaction with an epoxide component, the amount of amine being chosen such that the number of nitrogen-attached hydrogen atoms the number of epoxide groups by a factor of from 2 to 10, and the emulsifier being obtainable by reacting diepoxides or polyepoxides with compounds that are at least difunctional with respect to epoxides, optionally with compounds D that are monofunctional with respect to epoxides, and with amines G which contain at least one tertiary and at least one primary or at least two secondary amino group(s).
