摘要

Heat curing epoxy resin composition, reinforcement element, process for bonding heat stable substrates, use of said composition and structural foam. The present invention relates to the field of heat curing epoxy resin compositions and their use, more particularly in motor vehicle construction and sandwich panel construction. The heat curing epoxy resin compositions of the invention comprise, in addition to the epoxy resin components A1, optionally A2, a hardener component B, a carboxylic acid C and a hydroxyalkylamide or hydroxyalkylurea H, an accelerator E for activating component conversion A1, A2 and B. The compositions and structural foams produced therefrom are notable for their high mechanical strength, high glass resistance and good adhesion ability on metallic and non-metallic substrates, and it is possible at the same time to dispense with the use of toxic or flammable breath.
