  • Publication number: 20100266809
    Abstract: The present invention relates to a method of producing an edging-fold bond. For this purpose use is made more particularly of high-viscosity adhesives. The method features reduced bubble formation within the edging fold and also within the sealant (where present) that seals the edging-fold seam. More particularly the adhesive comprises spacers which further reinforce this effect.

  • Publication number: 20100184924
    Abstract: The invention relates to viscosifiers, especially terminated polymers that have functional terminal groups, said polymers being pre-extended by polyamines, polymercaptans, (poly)aminoalcohols, (poly)mercaptoalcohols or (poly)aminomercaptans and being reacted to give polymers that are terminated by other functional groups. The viscosifiers have a low content in educts or educt descendants that deteriorate the properties of compositions. They are also characterized in that the formation of high-molecular addition products is considerably reduced or even excluded so that products obtained have low viscosity and good storage stability. The epoxy-terminated polymer of formula (I) is especially preferred.

  • Publication number: 20100183863
    Abstract: A foam is disclosed that can be cured by heat having, for example, 10 to 80 vol. % of at least one gas and a compound that can be cured by heat. The foam can include at least one polyurethane polymer and at least one curing agent that can be activated by increased temperature. Foams that can be cured are suitable as flues, sealing compounds, or for the production of coatings, and can be cured by heat for structural adhesive bonds and for lining in vehicle construction.

  • Publication number: 20100116433
    Abstract: The invention relates to compositions containing at least one solid epoxide resin A, at least one polymer B of formula (I), at least one thixotropic agent C made from a urea derivative and at least one curing agent for epoxide resins D activated by high temperatures. The compositions are particularly suitable for use as adhesives. Low-temperature impact-resistant adhesives can be produced for use in particular as structural adhesives.

  • Publication number: 20100087588
    Abstract: Embodiments relate to viscosifiers that are terminated polymers that have functional terminal groups. The polymers being pre-extended by polyepoxides and being reacted to give polymers that are terminated by other functional groups. The viscosifiers have a low content in educts or educt descendants that deteriorate the properties of compositions and considerably reduce or even exclude the formation of high-molecular addition products so that the products obtained have low viscosity and good storage stability.

  • Publication number: 20100048828
    Abstract: Viscosifiers, especially terminated polymers that have functional terminal groups, the polymers being pre-extended by polyols and being reacted to give polymers that are terminated by other functional groups, are produced. The viscosifiers have a low content in educts or educt descendants that deteriorate the properties of compositions. The formation of high-molecular addition products is considerably reduced or even excluded so that the products obtained have low viscosity and good storage stability. The epoxy-terminated polymer of formula (I) is especially preferred.

  • Publication number: 20090324958
    Abstract: Described are heat hardening compounds which contain at least one epoxy resin, A, with on average more than one epoxy group per molecule, at least one impact-strength modifier, B, at least one crack promoter, C, as well as at least one hardener, D, for epoxy resin, which is activated by raised temperature. Silicate layers such as mica or talc and graphite are particularly suitable as crack promoters, C.

  • Publication number: 20090288766
    Abstract: Discussed are heat-curable epoxy resin compositions containing at least one epoxy resin A with, on average, more than one epoxide group per molecule, at least one curing agent B for epoxy resins, which is activated by an increased temperature, at least one terminally blocked polyurethane prepolymer of formula (I) and at least one epoxide-terminated polyurethane prepolymer of formula (II). The epoxy resin compositions are particularly suitable for use as one-component, heat-curable adhesives and are characterized by excellent mechanical properties, high glass transition temperatures and high impact resistance.
