ABSTRACT:
A substrate is coated with an essentially water-free composition. The composition includes a superabsorbent polymer that absorbs from about 25 to greater than 100 times its weight in water and a material for lubricating the substrate. The superabsorbent polymer may be a polymer of acrylic acid, acrylamide or acrylate. Also included is a method for protecting a substrate from the effects of water or water migration.
