Abstract

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).
