  • Two-component epoxy adhesive composition
    Patent number: 7951456
    Abstract: A two-component epoxy adhesive composition comprises a) a first component comprising a first epoxy resin and a 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 having a molecular weight of less than 450 g/mole. 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 from 0.01:1 to 0.5:1. The mixing of components a) and b) results in a wash-off resistant composition upon heat-curing in a crash-stable structural adhesive.
    Type: Grant
