Abstract:
1. A two-component epoxy adhesive composition comprising a) a first component comprising a first epoxy resin and a second epoxy resin, the second epoxy resin being flexibilized by an elastomer, and b) a second component comprising at least one amine compound with one or more primary and/or secondary amino groups, said amine compound having a molecular weight of less than about 450 g/mol, wherein the weight ratio of the first component a) to the second component b) is from about 2:1 to about 10:1, 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 about 0.06:1 to about 0.2:1, and the reaction of the two components a) and b) after mixing results in a wash-off resistant composition, said wash-off resistant composition resulting upon heat-curing in a crash-stable structural adhesive.
