Abstract

The present invention relates to a two-component epoxy adhesive composition comprising The ratio of the total number of amino groups of the amine compound to the total number of epoxy groups of the epoxy resins is 0.01:1 to 0.5:1. The mixing of the two components a) and b) results in a wash-off resistant composition. Said wash-off resistant composition results upon heat-curing in a crash-stable structural adhesive.
