ABSTRACT:
Processes for uniformly coating substrates, including applying fluid substantially simultaneously onto at least two sides of a substrate. In one aspect, the invention provides positioning a substrate above one or more fluid applicators, and flowing fluid through the one or more fluid applicators upwardly onto the substrate, the fluid applied with a controlled volume per unit surface area of the substrate. A substrate surface also may be aligned along a substantially vertical plane with fluid being applied laterally. In another aspect, at least one fluid applicator faces a first side of a substrate and at least one applicator faces a second side of the substrate, and fluid flows through the fluid applicators onto the first and second substrate sides, the fluid applied with a controlled volume per unit surface area of the substrate.
