Abstract: Thermosetting epoxy resin compositions on the one hand at room temperature in the incompletely cured state exhibit extremely slight alteration in shape and on the other hand develop a high surface tack, and, moreover, in the fully cured state are of high impact strength and at the same time exhibits high adhesion, particularly to metallic substrates. These compositions are ideally suited to the production of self-adhesive reinforcing elements.

Abstract: A one-component thermosetting epoxy resin adhesive, including a) at least one epoxy resin A having on average more than one epoxide group per molecule; b) at least one latent hardener for epoxy resins; and c) at least one carboxylic acid selected from substituted or unsubstituted succinic acid and substituted or unsubstituted phthalic acid, wherein the epoxy resin adhesive contains 1.7 to 15 mmol of the at least one carboxylic acid per 100 g of epoxy resin adhesive, and the epoxy resin adhesive has a viscosity of more than 10 000 Pas at 25° C.

Abstract: The present invention relates to a self-adhesive article comprising a non-random fabric of bundles of carbon fibres and a thermosetting epoxy resin composition. The self-adhesive article exhibits high surface adhesion and excellent dimensional stability at room temperature. The self-adhesive article is ideally suited to reinforce structural components, particularly vehicles or ancillary vehicle components. The structural components reinforced by the self-adhesive article exhibit improved impact and torsional strength.
