  • Method for coating a substrate
    Patent number: 5866210
    Abstract: A method for coating a substrate having a plurality of channels with a coating media in which the substrate is partially immersed into a vessel containing a bath of the coating media with the volume of coating media lying above the end of the immersed substrate being sufficient to coat the substrate to a desired level. A vacuum is then applied to the partially immersed substrate at an intensity and time sufficient to draw the coating media upwardly from the bath into each of the channels to form a uniform coating profile therein.
