    U.S. patents
    Issued After Nov. 1, 1999

    Continuous Processing of Powder Coating Compositions
    U.S. Patent 5,975,874
    Issued: Nov. 2, 1999
    Inventors: A.T. Daly, et al
    Assigned to Morton International Inc.
    Systems and apparatus combinations for producing a powder coating are provided wherein a stream of a powder coating precursor, including at least one resin and at least one additional powder coating ingredient, is contacted with a process fluid effective to reduce the viscosity of the powder coating precursor to allow processing of the powder coating precursor at a lower temperature.

    U.S. Patent 5,981,650
    Issued: Nov. 9, 1999
    Inventors: M. Geck, et al
    Assigned to Wacher-Chemie GmbH
    The invention relates to the use of precross-linked silicone elastomer particles with an organopolymer shell as the formulation constituent in powder coating material compositions based on thermoplastic or thermosetting binding agents.

    Process for Preparing Coating Powder Compositions and Use of Same for Making Coatings
    U.S. Patent 5,981,696
    Issued: Nov. 9, 1999
    Inventors: D. Saatweber, et al
    Assigned to Herberts GmbH
    The invention concerns a process for preparing powder coating compositions in which one or more base resins and one or more hardeners, each of which is in solid form, is dissolved with a low-molecular compound above its critical pressure and critical temperature. This low-molecular compound is inert with respect to the base resins and hardeners and is in gaseous form under normal operating conditions with respect to pressure and temperature. The pressure of the resultant solution is then reduced, for example, by spraying. The resulting powder coating composition can be sprayed directly onto a substrate to be coated. Powder coatings can also be recycled according to the process of the invention.

    Thermosetting Powder Coating Material and Method
    U.S. Patent 5,998,507
    Issued: Dec. 7, 1999
    Inventors: T. Adachi, et al
    Assigned to Kansai Paint Co. Ltd.
    A method for preparing a thermosetting powder coating material comprising: dispersing and mixing a base resin and a cross-linking agent in a dispersing and/or mixing machine equipped with a decompression device at a temperature in the range of 40 to 200°C to form a dispersed mixture, the dispersed mixture optionally containing a solvent and a pigment, optionally eliminating at least a portion of the solvent under reduced pressure, adding water to the dispersed mixture, reducing the pressure and lowering the temperature of the dispersed mixture to a temperature equal to or less than the softening point of the dispersed mixture, and bringing the dispersed mixture into a powder state or a granule state by dispersion force of the dispersing and/or mixing machine.

    Coating Powder for High-Temperature Resistant Coatings
    U.S. Patent 5,998,560
    Issued: Dec. 7, 1999
    Inventors: O.H. Decker, et al
    Assigned to Morton International Inc.
    A powder coating for providing a high-temperature resistant coating has a silicone resin binder system that is either substantially all silicone resin or an -OH- functional silicone resin adduct plus blocked, multi -NCO- functional curative. The powder coating is pigmented with titanium dioxide, which is either uncoated or coated with a sufficiently low level of an inorganic oxide such that when slurried in water, the pH is 7 or above. The powder coating preferably contains at least 40 phr mica and/or calcium metasilicate, preferably between 2 and about 20 phy aluminum. The powder coating may also contain zinc to protect the underlying substrate from corrosion and high-temperature pigments, particularly ceramic pigments.

    Dual-Thermal and UV-Curable Powder Coatings
    U.S. Patent 6,005,017
    Issued: Dec. 21, 1999
    Inventors: A.T. Daly, et al
    Assigned to Morton International Inc.
    Opaquely pigmented or thick-filmed powder coatings for heat-sensitive substrates, including wood, wood composites such as medium-density fiberboard, and plastics, can be fully cured, especially near the substrate, through the incorporation of a dual-cure system in the powder comprising a thermal initiator, such as a peroxide, along with a UV initiator. The UV initiator cures the surface, while the thermal initiator cures at the substrate. Surprisingly, virtually no pregelation occurs during the heated melt and flow-out step prior to UV curing. Consequently, the hardened film finish formed on the surface exhibits exceptional smoothness, which is comparable to that of traditional UV-curable powders. The hardened film finish is also fully cured and exhibits exceptional adhesion to the substrate, which cannot be achieved with traditional pigmented UV-curable powders. Although the dual-cure system includes a thermal aspect, these powder coatings are especially suited for coating heat-sensitive substrates. The dual-thermal and UV-curable powders still cure at significantly lower temperatures and significantly faster rates than traditional heat-curable powders to make them safe for coating heat-sensitive substrates.

    Nonhazing UV-Curable Powder Coatings Containing Crystalline Resins
    U.S. Patent 6,011,080
    Issued: Jan. 4, 2000
    Inventors: A.T. Daly, et al
    Assigned to Morton International Inc.
    This invention provides a UV-curable powder coating composition comprising a particulate blend of a noncrystalline unsaturated polyester base resin, a crystalline unsaturated cross-linker resin copolymerizable with the base resin, and a photoinitiator, that exhibits reduced or eliminated hazing in the cured coating formed when cured at low temperatures. This is accomplished by incorporating in the powder composition a recrystallization inhibitor, which is comprised of a crystalline epoxy resin. When this powder blend is melted for curing, all the crystalline resin species tend to separate and recrystallize out of the molten powder slower and less completely than they do in the absence of the recrystallization inhibitor. This prevents a visible haze from quickly developing on the surface of the molten coating before the coating can be cured with UV radiation.

    Powder Coating Process Using Two or More Kinds of Powder Paint
    U.S. Patent 6,015,585
    Issued: Jan. 18, 2000
    Inventors: M. Yamaguchi, et al
    Assigned to Honda Giken Kogyo Kabushiki Kaisha
    Powder coatings of different color brightness not deposited on the work to be coated are recovered as a mixture, and a fresh coating of high- or low-color brightness is added to the mixture to adjust its color brightness and thereby prepare a fresh mixture of medium-color brightness.

    Thermosetting Powder Coating Composition
    U.S. Patent 6,015,864
    Issued: Jan. 18, 2000
    Inventors: Koenraadt, Martinus Adrianus Anthonius Maria, et al
    Assigned to Akzo Nobel NV
    Proposed is a thermosetting powder coating composition comprising a mixture of particles reactive towards one another, optionally in combination with a catalyst, with a portion of the reactive particles comprising a polymer reactive towards oxetane groups while another portion comprises an oxetane groups containing cross-linking agent having an oxetane functionality of more than 1. The quantity of oxetane oxygen in the cross-linking agent preferably is at least 0.4 weight percent. The reactive polymer preferably is a polymer having groups reactive towards oxetane, such as carboxyl, epoxy, oxetane, anhydride and hydroxyl, with preference being given to a polyester or a hydroxypolyacrylate.

    Method for Producing Low-Gloss Appearance With UV-Curable Powder Coatings
    U.S. Patent 6,017,593
    Issued: Jan. 25, 2000
    Inventors: A.T. Daly, et al
    Assigned to Morton International Inc.
    Low-gloss appearance in a coating derived from UV-curable powder coatings can be achieved by using a UV-curable powder containing crystalline resins or blends of crystalline and amorphous resins and after heat-fusing the powders together, allowing the crystalline resins in the coating to cool and recrystallize to a low-gloss finish before curing with UV.

    Dual-Thermal and UV-Curable Powder Coatings
    U.S. Patent 6,017,640
    Issued: Jan. 25, 2000
    Inventors: J. Muthiah, et al
    Assigned to Morton International Inc.

    Unsaturated Polyester Powder Coatings With Improved Surface Cure
    EP 0 957 142 A2
    Published: Nov. 17, 1999
    Inventors: J. Muthiah, et al
    Assigned to Morton International Inc.

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.
