Epoxy resin adhesive with high compressive strength
The present invention relates to an epoxy resin adhesive comprising at least one epoxy resin in the resin component, at least one adduct AD which is flowable at room temperature, comprises primary amino groups and is formed of (i) at least one polyepoxide and (ii) at least one amine of the formula (I) and optionally further amines, and additionally at least one accelerator B with at least one dimethylamino group in the hardener component, and in total at least 50 wt% of at least one inorganic filler. The epoxy resin adhesive has little odour and good workability, develops strength rapidly at room temperature and in the cold, and cures to high strengths, especially high compressive strengths, and high forces of adhesion to substrates such as steel, composite carbon fibre materials (CRP) and concrete.
