Abstract:
A method for applying a fluid onto a surface of a solid substrate, said method comprising:(a) positioning a distribution member, said distribution member having an upper surface and a lower surface and including a permeable portion having channels therethrough, such that the lower surface of the distribution member is in opposing relation to the surface of the substrate and separated therefrom by a spacer thereby defining an application volume between the lower surface of the distribution member and the substrate surface; (b) dispensing a fluid volume of the fluid onto the upper surface of the permeable portion of the distribution member such that the fluid penetrates and is retained by the permeable portion of the distribution member wherein said fluid volume does not substantially exceed said application volume; and (c) applying a distribution pressure differential between the upper and lower surfaces without using a squeegee such that a portion of the fluid passes through the channels of the permeable portion of the distribution member and onto the solid substrate surface.
