Abstract
The invention involves a fluid treatment device and fluid treatment method to solution or melt coat or impregnate a resin or polymer to a predetermined, metered thickness into a substrate. The invention is effective in impregnating or coating various substrates in both a continuous or batch process on one side, two sides, or in the case of a porous substrate, penetration and complete saturation is possible. The invention offers significant advantages and benefits over existing methods and equipment and allows the coating or impregnation process to be performed at lower cost and higher efficiency with increased environmental safety.
