A thermally curable adhesive in strip or film form, having a thickness in the range of 0.1 to 5 mm, containing: a) at least one reactive epoxy prepolymer, b) at least one latent hardener for epoxies, and c) one or more elastomers that are selected from: c1) thermoplastic polyurethanes, c2) thermoplastic isocyanates, and c3) block copolymers having thermoplastic polymer blocks. Further components can additionally be contained, for example a blowing agent for foaming. The adhesive in the uncured state at 22° C. is bendable or wrappable and can be extended at least 100% before tearing. It can be laid onto a foil. It can be used, for example, for adhesive bonding of planar, tubular, or cylindrical components, preferably components made of metal, wood, ceramic, or ferrites.
