The addition of nanoparticles to the matrix material may significantly reduce the viscosity of the mixture comprising the liquid matrix material and the microspheres. Thereby, even a mixture comprising a very high content of microspheres in access of 60 Vol.-% can still be handled and e.g. filled in a mould and/or be de-gassed. Thus, a rigid foam material having low specific weight and high electrically insulating properties can be produced.

  • Patent number: 7600957
    Abstract: An expandable sealant is provided for a fastener including a threaded defining surface. The fastener includes the expandable sealant as a coating adhered to at least a portion of the thread-defining surface to lock the fastener in place and to expand to fill space between the thread-defining surface of the fastener and an aperture through which the fastener is passed to seal the aperture to prevent fluid and gases from passing therethrough.

  • Publication number: 20090176903
    Abstract: Expandable, thermally curable compositions containing at least one epoxy resin, at least one polyester, at least one blowing agent, and at least one curing agent are useful as adhesives and structural reinforcement materials. When foamed and adhered to a metal substrate surface, such polyester-modified foamable compositions can exhibit improved adhesion to the substrate surface after exposure to a corrosive environment, as compared to compositions that do not contain polyester. Furthermore, these compositions can exhibit improved flow properties in the uncured state at temperatures between 50 and 100° C. They are granulatable, with the granules produced thereby having non-tacky surfaces at room temperature and being capable of being readily processed into molded objects by injection molding processes.

  • Patent number: 7473715
    Abstract: The present invention relates to methods, materials, and products for forming a foamed product, comprising the steps of combining an epoxy-based component with an amine-based component. The epoxy component is cross-linked through a polymerization reaction catalyzed by the amine formulation. In this regard, an reactive mixture or exothermic reaction is created between the epoxy component and the amine component when combined. The heat generated by the exothermic reaction softens a thermoplastic shell of a blowing agent formulated within the epoxy component thereby enabling a solvent core within the thermoplastic shell of the blowing agent to expand from the heat generated by the exothermic or reactive mixture.

  • Patent number: 7473717
    Abstract: Expandable thermosettable compositions containing at least one epoxy resin, at least one finely divided thermoplastic polymer powder, at least one blowing agent, at least one curing agent, and at least one filler are suitable for the production of thermosetting laminated bodies with a tacky surface. These laminated bodies can be produced and handled in a simple manner and are suitable for stiffening and reinforcing flat structural components, in particular vehicle body structural components, such as vehicle body frames, doors, trunk lids, engine hoods and/or roof components in automobile construction. The expandable thermosettable compositions are also suitable for the production of thermosetting, thermally expandable shaped articles for reinforcing hollow structural members by the injection molding process. In preferred embodiments, the composition is injected onto a metallic or thermoplastic carrier.

  • Patent number: 7119149
    Abstract: The present invention is directed to a high expansion two-component structural foam that expands to about twice its original volume while maintaining good cell structure. The foam of the present invention is based on epoxy resins. Each component of the foam system exhibits storage stability, e.g., no phase separation, yet reacts when combined to provide a cured material having exceptionally good compression strength and modulus. The blowing system used to prepare the foam produces a foam which is uniform in appearance and is essentially free of the large voids often found in conventional two-part thermosettable compositions, even when a relatively large mass is utilized.
