The first component and the second component are separate as delivered to the site of application. The first component and the second component are applied onto a substrate so that the granules are adhered to the substrate by the polymeric coating composition. The polymeric coating composition is then allowed to cure to form a fire-retardant coating. The resulting fire-retardant coating affords surprising fire retardancy performance.Type: GrantFiled: November 7, 2006Date of Patent: November 16, 2010Inventor: Laxmi C. Gupta

Patent number: 7820238Abstract: A method of manufacturing homogenous metal matrix composite (MMC) powders and using the powders as the feedstock with cold spray deposition is described to produce composite coatings and freestanding bulk forms. Measured quantities of metal and ceramic powders having predetermined particle sizes are blended to produce homogeneous MMC powders. Spray parameters and procedures are controlled to produce dense, strong and well-bonded MMC coatings on any substrate.Type: GrantFiled: December 20, 2006Date of Patent: October 26, 2010Assignee: United Technologies CorporationInventors: Andrew DeBiccari, Jeffrey D. Haynes, Douglas A. Hobbs, Jeganathan Karthikeyan

Patent number: 7815999Abstract: An insulated conductive particle for an anisotropic conductive film is disclosed. One embodiment of the particle includes a conductive particle and insulating fixative particles discontinuously fixed on the surface of the conductive particle. The insulating particles provides insulation with other adjacent insulated conductive particles, while the insulated conductive particle is electrically connected between electrodes with the insulating fixative particles being deviated from its position. The instant disclosure also provides a method for manufacturing the insulated conductive particle, an anisotropic conductive adhesive film containing the insulated conductive particles, and an electrically connected structure using the film.Type: GrantFiled: November 10, 2006Date of Patent: October 19, 2010Assignee: Cheil Industries, Inc.Inventors: Jin Gyu Park, Tae Sub Bae, Jung Bae Jun, Jae Ho Lee, Jae Geun Hong
