Abstract: A method of applying a powder coating to a length of a lignocellulosic material. The method comprises impregnating the length of lignocellulosic material with an impregnating composition (i) a dicarboxylic anhydride or a tricarboxylic anhydride dissolved in non-aqueous solvent; (ii) an isocyanate thermosetting resin dissolved in a non-aqueous solvent; or (iii) a combination of (i) or (ii). Any excess impregnating composition is then removed from the lignocellulosic material. Non-aqueous solvent is also removed and the impregnated lignocellulosic material is placed in either an electrostatic field or in a fluidized bed and a powder coating composition is applied thereto so that the powder coating composition adheres to the lignocellulosic material. The impregnated and coated lignocellulosic material is then subjected to elevated temperatures to polymerise and/or cross-link the resin and cure the powder coating composition to form a powder coating. The length of lignocellulosic material may be a sheet of paper, wood or wood veneer. A typical solvent is dichloromethane or liquid carbon dioxide.

Abstract: In substrates, such as wood substrates, having sharp edges, corners and other surface discontinuities, in a front appearance surface, non-functional machining, such as formation of grooves, is performed on the rear non-appearance surface adjacent the surface discontinuities. Coating powder is applied, e.g., electrostatically, to the appearance surface of the substrate and the coating powder fused or fused and cured to form a continuous coating on the appearance surface of the substrate. The rear surface machining reduces cracking of the coating at the front surface discontinuities.In some cases, non-functional machining is distributed over the entire non-appearance surface of the work-piece to promote out-gassing of volatiles to the non-appearance surface, thereby eliminating out-gassing-caused defects in the coating formed on the appearance surface.

Abstract: A process is provided for coating a given surface of a heat sensitive metal article (e.g., thermally massive aluminum) with a high-cure-temperatureating-forming-powder. A first oven heating step elevates the metal article's temperature to a predetermined preheat cycle high-limit-of-heat-load-temperature. After a first predetermined period of time, the metal alloy article is withdrawn from the oven. A high-cure-temperature-coating-forming-powder is then sprayed onto the given surface of the metal article. The spraying, comprising first and second spray sequences, is initiated essentially immediately after withdrawal of the metal article from the oven. The first spray sequence is a single group of spray passes that applies a coating layer to fill the pores in the given surface with heat melted high-cure-temperature-coating-forming-powder. The second spray sequence builds up the total thickness of coating. A second oven heating step elevates the metal article's temperature to a predetermined cure cycle high-limit-of-heat-load-temperature for a second predetermined period of time.

Abstract: 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.
