  • Patent number: 7005476
    Abstract: Disclosed is a multicomponent, isocyanate-terminated or silane-functionalized coating and adhesive material which is continuously produced by mixing the individual components and by heating the latter and continuing mixing until said components reach a liquid state, wherein the resulting reactive coating and adhesive material is fed for direct use especially in profile sheathing plants, coating plants or the like. In the case of isocyanate-terminated material, one component has a reactive high-molecular weight starting polymer and a second component has a reactive isocyanate-terminated cross-linking agent. In the case of the silane- functionalized material, one component has a high-molecular weight starting material and a second component has a reactive, silane-functionalized cross-linking agent.

  • Patent number: 6924335
    Abstract: A thermal interface material (40) includes a polymer matrix (32) and an array of carbon nanotubes (22) incorporated in the polymer matrix. The polymer matrix has a thermally conductive first face (42) and an opposite thermally conductive second face (44). The carbon nanotubes are substantially parallel to each other, and extend between the first and the second faces. A preferred method for making the thermal interface material includes the steps of: (a) forming the array of carbon nanotubes on a substrate (11); (b) immersing the carbon nanotubes in a liquid prepolymer (31) such that the liquid prepolymer infuses into the array of carbon nanotubes; (c) polymerizing the liquid prepolymer to obtain the polymer matrix having the carbon nanotubes secured therein; and (d) peeling the polymer matrix having the carbon nanotubes off from the substrate to obtain the thermal interface material.

  • Patent number: 6420493
    Abstract: A two component chemically thermoset composite resin matrix for use in composite manufacturing processes includes a solvent free polyisocyanate component and a solvent free polyol component. The solvent free polyisocyanate component is either an aromatic polyisocyanate, an aliphatic polyiscyanate or a blend of both. The solvent free polyol component is either a polyether polyol, a polyester polyol or a blend of both. The polyisocyanate component and the polyol component are in relative proportions in accordance with an OH/NCO equivalent ratio of 1:1 to 1:2. The components form a relatively low cost polyurethane composite resin having a useful range of physical properties, without the emission of volatile organic compounds during curing.
