  • Patent number: 11939500
    Abstract: Diecuts and methods for closing of holes in metal sheets or in plastics parts are disclosed. The diecuts have a carrier composed of an assembly that comprises a metallic first layer having a thickness of 10 to 40 ?m, a second layer of a woven or laid glass fabric having a basis weight of 30 to 200 g/m2, an optional first adhesive third layer, an unexpanded expandable graphite fourth layer having a thickness of at least 0.2 to 3.0 mm, and a second adhesive fifth layer. The expandable graphite being present in the fourth layer to an extent of at least 80 wt % and fifth layer being formed by an adhesive having a basis weight of 300 to 1800 g/m2 and/or a thickness of 400 to 1800 ?m.

  • Publication number: 20240014486
    Abstract: Methods may seal or seal a continuous clearance in a substrate and comprise a) producing or providing a bonding element comprising: i) an adhesive layer comprising an adhesive, ii) a carrier layer disposed on the adhesive layer and comprising a first carrier ply, and b) adhering the bonding element by means of the adhesive layer to the substrate, so that the bonding element completely covers the continuous clearance and the continuous clearance is fluid-tightly sealed by the bonding element. The bonding element comprises a pressure opening region which is surrounded at least sectionally by a weakening region formed in the carrier layer, the mean thickness of the carrier layer in the weakening region being lower than the mean thickness of the carrier layer in the pressure opening region.

  • Patent number: 11845887
    Abstract: The present invention relates to a diecut especially for the permanent closing of holes especially in metal sheets or in plastics parts, having a carrier composed of an assembly, more particularly laminate in the specified layer sequence, of optionally at least one first layer, which is formed by a metallic layer having a thickness of 10 to 40 ?m, optionally at least one second layer, which is formed by a woven glass fabric or laid glass fabric having a basis weight of 30 to 200 g/m2, optionally at least one third layer, which is formed by a first pressure-sensitive adhesive having a basis weight of 70 to 200 g/m2, at least one fourth layer, which is formed by a flame-retardant foam having a thickness of at least 0.5 to 2.5 mm, and at least one fifth layer, which is formed by a second, acrylate-based pressure-sensitive adhesive having a basis weight of 300 to 1800 g/m2, preferably 360 to 1500 g/m2 and/or a thickness of 400 to 1800 ?m, preferably 800 to 1500 ?m.

  • Patent number: 11208581
    Abstract: Thermally vulcanisable, meltable adhesives and processes have a meltable polybutadiene-polyurethane, ground sulphur and optionally at least one vulcanisation accelerator, at least one filling material, at least one epoxide resin, at least one tackifier resin, bitumen, at least one softener and further auxiliary and additive materials, wherein said adhesives and processes can be thermally vulcanised within a temperature range of 130° C. to 230° C., such that same, as well as an adhesive strip produced from same, can be used for adhesion and/or sealing in the automotive industry, as well as in structural work on oiled sheet metal, and in the painting line on e-coated or otherwise painted sheet metal, for example, for crimp fold adhesion, for crimp fold sealing, for seam sealing, for lining adhesion, for hole closure and much more.

  • Patent number: 10946629
    Abstract: Diecuts are configured for permanent closing of holes and have a carrier comprising an assembly of at least two polymeric films. An upper film of the at least two polymeric films has a basis weight of at least 1.0 kg/m2 and a lower film of the at least two polymeric films consisting of at least two layers, wherein a first layer is in the form of a polymeric film and faces the upper film, and a second layer is in the form of a functional layer with a side of the lower film, facing away from the upper film, bears an applied adhesive composition.
