    摘要： Thermosetting powder coating compositions adapted to form a grainy textured finish on heat sensitive substrates, especially wood products, such as particle board, conductive particle board, and medium density fiber board, without damaging the substrates comprise an epoxy resin, particularly bisphenol A type epoxy resins having low viscosities, either a catalytic curing agent comprising an imidazole, a substituted imidazole, or adduct of an imidazole or substituted imidazole and an epoxy resin, or a curing agent comprising an adduct of a polyamine and an epoxy resin, or a combination of the catalytic curing agent and curing agent, a texturing agent, a flow control agent, optional extender, and optional pigment. The thermosetting powder coatings have a cure time/temperature ranging from about 30 seconds at about 350.degree. F. peak substrate temperature down to about 20 minutes at about 225.degree. F. peak substrate temperature which provides for either a rapid cure or low bake temperature to prevent excessive heat exposure to the heat sensitive substrate, resulting in substantially no physical or chemical degradation of the heat sensitive substrate during baking. The powder coatings are applied to heat sensitive substrates, especially wood products, through electrostatic spraying onto the substrate followed by heating to cure the textured finish uniformly on the surfaces and edges of the substrate. Electrostatic spraying is performed with a triboelectric or corona spray gun and heat curing is performed with a high intensity infrared oven, a convection oven, or combination. Coated heat sensitive substrates having continuous grainy textured finishes that are excellent for hiding substrate surface defects and later appearing scratches are obtained.

    摘要： A process of forming coatings on substrates by applying a layer of curable materials in dry powder form and then melting and curing the material is improved by compressing the layer using a flexible confining membrane. Less material is required to provide equivalent barrier protection and surface finish. The process is particularly applicable to applying dry powder coatings on temperature sensitive substrates, such as medium density fiberboard, in press apparatus, such as a membrane press, which have not commercially used dry powder coating materials previously.

    摘要： 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.
