    摘要： A method of applying a coating composition to a substrate utilizing a high transfer efficiency applicator is disclosed and provides coated article. The high transfer efficiency applicator comprises a plurality of nozzles, each being configured to apply a stream or stream of droplets of the coating composition to a substrate substantially without atomization, and an infrared emitter. The method includes providing a coating composition for overspray-free application to the high transfer efficiency applicator, and applying the coating composition via disposing a plurality of lines of the coating composition onto the substrate via the plurality of nozzles. The method also includes irradiating the coating composition via the infrared emitter during and/or after application to give an irradiated coating composition, and thereby form an overspray free coating layer on the substrate.

    摘要： A method of preparing a coated article is disclosed. The method includes providing a substrate bearing a partially-dehydrated aqueous coating layer. The method further includes providing a coating composition to a high transfer efficiency applicator, the high transfer efficiency applicator comprising a plurality of nozzles each being configured to apply a stream of the coating composition to a substrate substantially without atomization. The coating composition is a waterborne fluid that exhibits a near-Newtonian viscosity profile, and comprises a binder, a crosslinker, and a thickener. The method further includes applying the coating composition to the substrate with the high transfer efficiency applicator via disposing a plurality of lines of the coating composition onto the partially-dehydrated aqueous coating layer of the substrate via the plurality of nozzles, thereby forming an overspray free coating layer thereon.

    摘要： A nozzle plate defines at least one nozzle connected to the nozzle plate at a base, wherein the at least one nozzle has a height and a top having an inner width and an outer width, wherein a ratio of the height to the inner width is greater than 5, and wherein the nozzle plate comprises a borosilicate glass. The nozzle plate is formed via a method including providing a silicon wafer having a surface; providing a borosilicate glass wafer having a surface; etching the surface of the silicon wafer to form a plurality of trenches in the surface; anodically bonding the etched surface of the silicon wafer to the surface of the borosilicate glass wafer to form a two layer composite; heating the two layer composite at a temperature of at least about 750° C.; and releasing the silicon wafer from the borosilicate glass to form the nozzle plate.

    摘要： Methods and coating compositions for application to a substrate utilizing a high transfer efficiency applicator are provided. An exemplary method includes providing the coating composition to the high transfer efficiency applicator; applying the coating composition onto the substrate utilizing a high transfer efficiency applicator to form an applied layer, wherein a loss of volatiles after application through the high transfer efficiency applicator is less than about 1 weight percent based on a total weight of the coating composition; performing a partial polymerization via radiation of the applied layer; and after performing the partial polymerization of the applied layer, thermally curing and drying the applied layer. An exemplary coating composition has a pre-application viscosity, at a shear rate of 1000 s−1, of less than about 100 centipoise (cP), and a post-radiation-exposure viscosity at a shear rate of 0.1 s−1 of from about 500 cP to about 150,000 cP.
