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： A coating powder consisting essentially of generally spherical particles ranging in size from less than 2 to about 40 microns, 75% of whose volume consists of particles of from about 2 to about 20 microns in size, is provided by dissolving the components of the coating powder in a supercritical fluid without the aid of a surfactant and spraying the solution into a zone whose pressure is less than that of the fluid. A very smooth continuous film of a cured thermosettable coating powder is achieved even when the film thickness is less than 1 mil, e.g., from about 0.2 and greater. The advantages of powder coatings may now be realized fully in the automobile and can industries.

摘要： A coating powder comprising a macrocyclic oligomer and a ring-opening polymerization agent is applied to an article, fused, and converted to a linear polymer at a temperature of from about 160 to about 400° C. The powder has the low melt viscosity and friability of a thermoset powder but is converted at high fusing temperatures to a tough coating having the good impact resistance and good elongation of a thermoplastic powder. The oligomer is a polyester, polycarbonate, polyamide, polyimide, polyamideimide. The article may be coated electrostatically or in a fluidized bed.

摘要： 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.

摘要： A thermosetting epoxy resin powder coating composition is provided that comprises an epoxy resin composed of a diglycidyl ether of bisphenol A, a curing agent composed of a bisphenol A encapped diglycidyl ether of bisphenol A, and a cure catalyst composed of an imidazole adducted to a diglycidyl ether of bisphenol A, in which the ratio of curing agent to epoxy resin is below 70% stoichiometry, and preferably between about 10% and 60% stoichiometry. The thermosetting epoxy resin powder coating composition not only exhibits the desired flexibility and fast cure speeds, but also exhibits superior adhesion and superior resistance to delamination and cathodic disbondment, preferably having cathodic disbondment values typically less than 4 mm radial disbondment, and preferably less than 2 mm radial disbondment. Such properties are highly advantageous for protective powder coatings used on rebars and pipelines. The marked improvement in adhesion combined with good flow out behavior provide the thermosetting epoxy resin powder coating composition with the ability to effectively adhere to steel strappings and other dirty, oily and scaly metallic substrates. The thermosetting epoxy resin powder coating composition also begins to cure at very low temperatures for acceptable oven bake times. This property is highly advantageous for protective and decorative powder coatings used on wood and other heat sensitive substrates.

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.
