Abstract: The subject matter of the present application is a curable adhesive composition having PTC characteristics after curing, containing (i) a reactive binder system, based on an epoxy-resin-component and a curing agent-component, (ii) particles of a carbon modification in a range of 0.01 wt % to 15.0 wt %, based on the total weight of the curable adhesive composition, and (iii) copper powder in a range of 0.5 wt % to 5.0 wt %, based on the total weight of the curable adhesive composition, wherein the reactive binder system comprises>70 wt % of all organic polymers of the adhesive composition.

Abstract: The invention relates to a method for connecting a first tube to a second tube, the tubes being interconnected in an overlapping region by means of an adhesive that fills a gap in the overlapping region between the tubes. Said method is characterized in that: a) adhesive is applied to the overlapping region of at least one of the tubes and the adhesive is selected in such a way that it is solid at temperatures of below 30° C.

Abstract: 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.

Abstract: The invention relates to a method for adhesively bonding a magnet onto the surface or into a slot of a rotor or stator of an electric motor or a generator, wherein i) the surface or surfaces to be glued of the magnet, rotor or stator are pre-coated with an adhesive that is not liquid at 22° C. and that does not cure without an activation step, iii) the magnet is brought into contact with the rotor or stator at the adhesive location, and iv) the adhesive is activated by heating or by high-energy radiation so that it cures, characterized in that the adhesive comprises a) at least one reactive epoxide prepolymer, b) at least one latent hardener for epoxies, and c) one or more elastomers. The adhesive preferably comprises a blowing agent. The invention further relates to a corresponding pre-coated magnet.
