Abstract

Epoxy resin compositions comprising polyepoxides having at least two 1,2-epoxide groups, which can be obtained by reaction of diepoxides or polyepoxides or mixtures thereof with monoepoxides, and one or more amines sterically hindered amines, such as disecondary polyoxyalkylenediamines, and/or diprimary diamines, if desired with the addition of further 1,2-epoxide compounds and also hardeners, and use thereof as a coating for crack bridging, as an adhesive and in powder surface coatings.
