DEVICES FOR COATING CONTOURED SURFACES

摘要

Provided are devices for coating (300) a contoured surface or a three-dimensional structure, and methods of making and using the same. The devices have geometries (308) that are in point contact with the contoured surface. The geometries are substantially rigid and are provided by a flexible applicator (306). In this way, the flexible applicator permits conformance to the surface contours, along with rigid point contact that provides uniform and consistent coverage of liquid material. Specifically, the devices comprise a handle (304) and an applicator (302) pliantly affixed to the handle, the applicator comprising a plurality of spaced geometries (308). The devices meter film-forming coating liquids onto contoured surfaces or three-dimensional structures to form uniform coatings and resulting uniform films.

主权项

1. A device for coating a contoured surface comprising:
a handle; an applicator pliantly affixed to the handle, the applicator comprising a flexible microreplicated material that comprises a plurality of spaced geometries, wherein the geometries are selected from the group consisting of pins, posts, cones, cylinders, pyramids, mushroom heads, cube corners, and J-hooks; wherein upon contact with the contoured surface, the geometries are in point contact with the contoured surface.
