Publication number: 20030143325Abstract: A method of powder coating a substrate includes cooling the non-metallic substrate, condensing a vapor at a surface of the non-metallic substrate, and disposing a coating powder at the condensed vapor. The vapor may be water, and the substrate may be non-metallic, preferably a wood, for example fiberboard or engineered wood. The powder coatings formed thereby are more uniform and less prone to distortion or cracking.Type: ApplicationFiled: January 27, 2003Publication date: July 31, 2003Inventor: Edward G. Nicholl

Patent number: 6432488Abstract: A powder coating composition and method of applying it to a substrate, such as medium density fibreboard, consisting of a glycidyl methacrylate resin, a dicarboxylic acid cross-linking agent, a catalyst selected from phosphines, phosphonium, ammonium 2-phenyl-2-imidazoline, substituted imidazoline and isopropyl imidazole Bis-A epoxy resin adduct and a matte texturing agent. The inventive formulation is able to create a matte texture finish on the surface of the substrate. Since the cured final coating is resistant to yellowing and moisture, it is of great utility in the kitchen cabinet making industry.Type: GrantFiled: July 28, 2000Date of Patent: August 13, 2002Assignee: Rohm and Haas CompanyInventors: Andrew T.

Publication number: 20010028132Abstract: Method for on-mold surface coating fiberglass-reinforced molded articles during their manufacture with environmentally friendly and physiologically safe thermosetting unsaturated polyester on-mold coating powders which serve as replacements for liquid gel coats. The thermosetting coating powders employed are adapted to cure at low temperatures to avoid causing thermal damage to the heat sensitive plastic molds which must be reused over and over again, and to cure in the presence of atmospheric oxygen to enable over coating with liquid fill resins and fiberglass, which constitute the bulk of the finished article, without having the fill resins bleed through the powder coating film and detrimentally affect the overall quality of the surface finish.Type: ApplicationFiled: March 16, 2001Publication date: October 11, 2001Inventors: Edward G. Nicholl, Navin B. Shah

Patent number: 6153267Abstract: An atomized fluid, such as a mist of water, is applied to a preheated substrate, such as wood, a wood product, paper, or ceramic just prior to or contemporaneously with electrostatically applying a coating powder to the substrate. The atomized fluid is absorbed or adsorbed by the substrate so as to enhance the charge-carrying capacity of the substrate to an extent necessary to promote efficient electrostatic application of the coating powder to the substrate.Type: GrantFiled: March 10, 1999Date of Patent: November 28, 2000Assignee: Morton International Inc.Inventors: Paul R.

Patent number: 6048949Abstract: Low temperature curable unsaturated polyester powder coatings suited for heat sensitive substrates with improved surface cure through incorporation of active hydrogen groups into the unsaturated polyester molecule. The unsaturated polyesters containing active hydrogens are derived from ethylenically unsaturated polyfunctional carboxylic acids and active hydrogen containing polyols. Full cure on the surface is obtained without the need for polyethylene waxes or oxygen-reactive curative resins that are commonly employed in order to prevent atmospheric oxygen from inhibiting the free-radical induced cure at the surface of the coating.Type: GrantFiled: May 11, 1998Date of Patent: April 11, 2000Assignee: Morton International, Inc.Inventors: Jeno Muthiah, Joseph J. Kozlowski, Navin B. Shah, Paul H. Radcliffe, Edward G. Nicholl
