Abstract: A coating apparatus is disclosed for applying a coating material on one or more zones of a substrate material. In one embodiment, the coating applicators have fluid-wicking strips that apply the coatings directly to the substrate, while in another embodiment, the fluid-wicking strips indirectly apply the coatings to the substrate via feed rolls. Metering mechanisms supply predetermined amounts of coating material to the fluid-wicking strips. Each coating applicator has a housing with a recess for receiving one the fluid-wicking strips therein. One of the fluid-wicking strips is mounted in each housing which has a plurality of transversely spaced passageways. Each passageway of each applicator housing is fluidly coupled to its own separate air actuated metering mechanism which dispenses coating material to the portion of the fluid-wicking strip adjacent thereto. A desired quantity of coating material is simultaneously delivered via the metering mechanisms to each of the applicator housings.

Abstract: The invention is a method for improving the flow of particulate lacquer powders when the lacquer powders are coated on a substrate and the substrate heated to fuse the lacquer particles to provide a finished lacquer surface on the substrate. The flow control agent is an oxazine, oxazoline, oligoxazine or oligoxazoline and salts of the compounds with protonic acids. The flow control agents when included in power lacquer formulations improve the flow of the lacquer when the powder lacquer coated substrate is heated to fuse the coating.
