Abstract
An apparatus for distributing a hydrophobic material in a substrate includes a first roller, second roller that engages the first roller to form a nip, a heater operatively connected to the first roller and configured to heat the first roller to a first temperature that is greater than a second temperature of the second roller, and a substrate transport configured to move a substrate through the nip at a predetermined velocity. The first roller engages a first side of the substrate and the second roller engages a second side of the substrate to enable the hydrophobic material to penetrate into the substrate.
