Abstract:
Provided are devices for coating a contoured surface or a three-dimensional structure, and methods of making and using the same. The devices have geometries that are in point contact with the contoured surface. The geometries are substantially rigid and are provided by a flexible applicator. 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 and an applicator pliantly affixed to the handle, the applicator comprising a plurality of spaced geometries. The devices meter film-forming coating liquids onto contoured surfaces or three-dimensional structures to form uniform coatings and resulting uniform films.
