Patent number: 6416817Abstract: A process of preparing an oxygen barrier coating using a compound of the general formula RaX3−aSi—Z—SiX3−aRa wherein Z is R′NH(R′NH)pR′, each R is selected from the group consisting of a hydrogen atom and a hydrocarbon group, each X is selected from the group consisting of an alkoxy group with 1 to 4 carbon atoms, a halogen atom, an oxime group or an acyloxy group, each R′ is a divalent hydrocarbon group having 1 to 12 carbon atoms; a is from 0 to 3 and p is 0 or 1. The invention further comprises compositions incorporating the above compound. Coatings prepared may be used in packaging applications as a top coat, or a primer for further coatings.Type: GrantFiled: March 3, 2000Date of Patent: July 9, 2002Assignees: Dow Corning SA, E.G. Technology Partners, L.P.Inventors: Imtiaz J. Rangwalla, John E. Wyman, Patrick Jacques Jean Merlin, Shrenik Mahesh Nanavati, Laurence Gallez

Patent number: 6299721Abstract: In one embodiment, the present invention relates to a method of increasing resin dust resistance of metal foil comprising contacting the metal foil with an inert silane, titanate or zirconate compound to form a resin dust resistant film having a thickness from about 0.001 microns to about 1 micron on a surface of the metal foil. In another embodiment, the present invention relates to a method of treating metal foil comprising contacting a first side of the metal foil with a hydrocarbylsilane solution to form a resin dust resistant film on a surface of the metal foil, the hydrocarbylsilane solution comprising from about 0.01% to about 10% v/v of a hydrocarbylsilane; and laminating a second side of the metal foil to a prepreg.Type: GrantFiled: December 14, 1998Date of Patent: October 9, 2001Assignee: Gould Electronics InclInventors: Charles A. Poutasse, Michael A. Centanni

Patent number: 6274200Abstract: A ferrous-alloy aircraft structural component such as a fastener is prepared by providing a ferrous-alloy component precursor that is not in its final heat-treated state, and coating with an aluminum-containing, curable organic coating material having a non-volatile portion that is predominantly organic and is curable at about the ferrous-alloy component's tempering temperature. The coated, ferrous-alloy is then tempered to concurrently impart predetermined metallurgical properties to the finished, ferrous-alloy material, and cure the organic, aluminum-containing coating.Type: GrantFiled: September 11, 1998Date of Patent: August 14, 2001Assignee: Boeing North American, Inc.Inventors: Steven G. Keener, Kevin T. Ruth

Patent number: 6228428Abstract: A method of forming a polyfluorocarbon coating on a razor blade cutting edge comprises subjecting a fluorocarbon polymer having a molecular weight of at least 1,000,000 in dry powder form to ionizing irradiation to reduce the molecular weight of the polymer forming a dispersion of the irradiated polymer in a volatile organic liquid, spraying the dispersion on to a razor blade cutting edge, and heating the coating obtained to sinter the polyfluorocarbon. The polyfluorocarbon preferably is polytetrafluoroethylene and irradiation preferably is effected to obtain a telomer having a molecular weight of about 25,000.Type: GrantFiled: April 28, 1994Date of Patent: May 8, 2001Assignee: The Gillette CompanyInventor: Hoang Mai Trankiem

Patent number: H1967Abstract: A method of improving the adhesion of an ink jet ink formulation to a substrate, which method includes adding to the ink jet ink formulation an amount of a chelate of a transition metal or a chelate of a mixture of transition metals effective to improve the adhesion of the ink jet ink formulation to the substrate; printing the substrate with the chelate-containing ink jet ink formulation; and treating the printed substrate with heat for a time and at a temperature to further improve the adhesion of the ink jet ink formulation to the substrate. The ink jet ink formulation typically will include a diluent system and colorant. The chelate typically will be present in the ink jet ink formulation in a range of about 0.001 up to about 20 percent by weight, based on the total weight of the chelate-containing ink jet ink formulation. A particularly desirable chelate is zirconium lactate. The present invention also provides an article and a substrate produced by the foregoing method.Type: GrantFiled: July 2, 1998Date of Patent: June 5, 2001Assignee: Kimberly-Clark Worldwide, Inc.Inventor: Jerome A.
