  • Patent number: 9039854
    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.

  • Patent number: 8790779
    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.

  • Patent number: 8778129
    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.

  • Publication number: 20110094992
    Abstract: Method for manufacturing a heat exchanger, wherein two neighboring metal tubes (1) are joined to one another in the overlap areas at their open ends by a U-shaped end tube (3), using an adhesive (5), wherein a) the adhesive is applied to the overlap areas of the U-shaped end tube, and wherein the adhesive is selected so that after being applied to the overlap areas of the U-shaped end tube and before being bonded to the metal tubes, the adhesive is solid and not tacky at temperatures below 30° C. and does not cure without an activation step, b) the end tube with the overlap area and the adhesive applied thereto is attached to the metal tubes or inserted into the metal tubes, and c) the adhesive is activated thermally or by bombardment with high-energy radiation either before or after step b), so that it cures after step b) and bonds the metal tube to the U-shaped end tube in the overlap area.
