Abstract:
An apparatus including: (a) a substrate including a deposition region and an optional uncoated region, wherein the deposition region includes a level intermediate region disposed between a first end region and a second end region, wherein the first end region includes a first raised surface portion extending above the level intermediate region and extending circumferentially around the first end region in a continuous manner; and (b) a dip coated layer over the entire deposition region.
Abstract:
A method for dip coating the exterior surface of a hollow substrate having an open first end and an open second end, the method including: (a) inserting a chuck assembly through the open first end into the substrate interior, wherein the chuck assembly includes a width changing apparatus and a polymeric member coupled to the width changing apparatus, wherein the chuck assembly defines a space that communicates with the substrate interior but is otherwise enclosed, wherein the space includes (i) a chamber and (ii) a passageway through a portion of the chuck assembly that permits the substrate interior to communicate with the chamber, wherein the width changing apparatus is disposed in the passageway but still allows airflow between the substrate interior and the chamber; (b) holding the substrate with the chuck assembly wherein the polymeric member forms a hermetic seal with the substrate; (c) contacting the substrate with a coating solution, starting from the second end, while the chuck assembly holds the substrate and the hermetic seal is maintained between the polymeric member and the substrate, wherein there is a closed area into which vapor from the coating solution can flow and the closed area is defined by the space of the chuck assembly and the substrate interior; and (d) separating the substrate and the coating solution to leave a layer of the coating solution on the exterior surface of the substrate.
Abstract:
A coating method for a hollow substrate including: (a) forming a seamed extended substrate unit composed of a substrate extension device and the substrate, and employing a chuck assembly to internally grip the substrate; (b) dip coating the extended substrate unit while the chuck assembly internally grips the substrate to deposit a layer first on the substrate extension device and then on the substrate; and (c) separating, subsequent to the dip coating the extended substrate unit, the substrate extension device from the substrate.
Abstract:
An apparatus comprising: (a) a substrate including a level intermediate region disposed between a first end region and a second end region; (b) a first external member disposed circumferentially around the first end region in a continuous manner and protruding above the level intermediate region, thereby resulting in a deposition region including the surface of the first external member covering the first end region, an optional exposed first end region portion, and the intermediate region; and (c) a dip coated layer over the entire deposition region, wherein the portion of the dip coated layer over the first external member and the optional exposed first end region portion is formed prior to the portion of the dip coated layer over the intermediate layer.
