Publication number: 20030036608Abstract: Heat sensitive substrates, as well as others such as metal or glass, are electrostatically coated with a thermosetting coating powder comprising a melt-mixed, chilled, chipped, and powdered blend of an epoxy resin and a catalyst therefore, and a powdered low temperature curing agent along with conventional additives. The coating powder is deposited on the substrate and heated to fuse, flow and cure. The mixture of resin and catalyst does not cure within the extruder but it is made to cure at low temperatures on the desired substrate by the separate addition of the curing agent to the powdered melt-mixed blend. A small amount of the low temperature curing agent, insufficient to cause substantial curing in the molten stage may be used in place of the catalyst.Type: ApplicationFiled: June 4, 1999Publication date: February 20, 2003Inventors: ANDREW T. DALY, GLENN D. CORRELL, JENO MUTHIAH, JOSEPH J. KOZLOWSKI, RICHARD P. HALEY, PAUL R. HORINKA, EUGENE P. REINHEIMER

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.

Patent number: 6348242Abstract: Low gloss appearance in a coating derived from UV curable powder coatings can be achieved by using UV curable powder containing crystalline components or blends of crystalline and amorphous components and after heat fusing the powders together, allowing the crystalline components in the coating time to flow out and recrystallize to form a matte low gloss finish at a temperature of about the melting point of the crystalline component before curing with UV radiation.Type: GrantFiled: February 16, 2000Date of Patent: February 19, 2002Assignee: Morton International Inc.Inventors: Andrew T.

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. Horinka, Andrew T. Daly, Michael G. Favreau, Glenn D. Correll, Edward G. Nicholl, Karl R. Wursthorn, Richard P. Haley

Patent number: 6136882Abstract: This invention provides a UV curable powder coating composition comprising a particulate blend of a non-crystalline unsaturated polyester base resin, a crystalline unsaturated crosslinker resin co-polymerizable with the base resin, and a photoinitiator, that exhibits reduced or eliminated hazing in the cured coating formed therefrom upon being cured at low temperatures demanded by certain heat sensitive substrates. This is accomplished by incorporating in the powder composition a recrystallization or haze inhibitor which is comprised of a crystalline epoxy resin. When this powder blend is melted for curing, the crystalline crosslinker resin visually appears to separate and recrystallize out of the molten powder less completely than it does in the absence of the recrystallization or haze inhibitor. This prevents a visible haze from developing on the surface of the coating upon curing with UV radiation.Type: GrantFiled: July 8, 1999Date of Patent: October 24, 2000Assignee: Morton International Inc.Inventors: Andrew T. Daly, Jeno Muthiah, Richard P. Haley, Owen H. Decker, Eugene P. Reinheimer, Matthew B. Snyder

Patent number: 6077610Abstract: Wood is electrostatically coated with a thermosetting powder coating system in which a mixture of a self-curing epoxy resin and a catalyst therefore is extruded and a low temperature curing agent are both pulverized and the powders are blended with conventional additives to make a coating powder which is deposited on a wooden substrate and heated to cure. The mixture of resin and catalyst does not cure within the extruder but it is made to cure at low temperatures by the separate addition of the curing agent. A small amount of the low temperature curing agent, insufficient to cause substantial curing during extrusion may be used in place of the catalyst.Type: GrantFiled: August 19, 1997Date of Patent: June 20, 2000Assignee: Morton International, Inc.Inventors: Glenn D.

Patent number: 6017593Abstract: Low gloss appearance in a coating derived from UV curable powder coatings can be achieved by using 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 radiation.Type: GrantFiled: March 31, 1998Date of Patent: January 25, 2000Assignee: Morton International, Inc.Inventors: Andrew T.

Patent number: 6017640Abstract: Opaquely pigmented or thick filmed powder coatings for heat sensitive substrates, such as wood, wood composites, for example, medium density fiber board, and plastics, that 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 throughout and exhibits exceptional adhesion to the substrate which cannot be achieved with traditional UV curable powders that have been pigmented.Type: GrantFiled: April 23, 1999Date of Patent: January 25, 2000Assignee: Morton International, Inc.Inventors: Jeno Muthiah, Andrew T.

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 of 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.Type: GrantFiled: August 19, 1998Date of Patent: January 4, 2000Assignee: Morton International, Inc.Inventors: Andrew T.
