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.

What is claimed is: 1. A substrate coated with an essentially water-free composition, wherein said composition comprises a superabsorbent polymer that absorbs greater than 100 times its weight in water in combination with a material for lubricating a surface wherein said material for lubricating a surface comprises: (1) a lubricating metal and alloy thereof, lubricating metal chalcogenide, halide, carbonate, silicate or phosphate, or a particulate lubricating metal nitride, or a carbon lubricant; or (2) a silicate ester, polyphenyl ether, organic phosphate, biphenyl, phenanthrene, or phthalocyanine compound; (3) said material for lubricating a surface optionally containing a lubricant comprising an organic lubricant, inorganic lubricant, or a lubricant additive; (4) or mixtures thereof. 2. The substrate of claim 1 wherein said organic lubricant comprises a petroleum lubricant, synthetic lubricant, grease, or solid lubricant, or combinations thereof and wherein said additive comprises a detergent or a dispersant. 3. The substrate of claim 1 wherein said superabsorbent polymer is neutralized or cross-linked, and is based on acrylic acid, acrylamide, or an acrylate. 4. The substrate of claim 2 wherein said superabsorbent polymer is neutralized or cross-linked, and is based on acrylic acid, acrylamide, or an acrylate. 5. The substrate of claim 1 wherein said organic lubricant comprises a petroleum oil, an organic ester, a silicone, or a glycol, or combinations thereof. 6. The substrate of claim 1 wherein said substrate comprises a cable. 7. The substrate of claim 1 wherein said substrate comprises a wire. 8. The substrate of claim 1 wherein the particle size of the superabsorbent polymer comprises from about less than 0.5 microns to about 300 microns. 9. The substrate of any one of claims 1-7 and 8 wherein said composition is a product produced by the process of combining said superabsorbent polymer with said material for lubricating a surface. 10. The substrate of claim 9 wherein said composition protects said substrate from the affects of water or water migration. 11. The substrate of one of claims 1-7 and 8 wherein said composition protects said substrate from the affects of water or water migration. 12. A method of protecting a substrate from the affects of water or water migration comprising coating said substrate with an essentially water-free composition, wherein said composition comprises a superabsorbent polymer that absorbs greater than 100 times its weight in water in combination with a material for lubricating a surface wherein said material for lubricating a surface comprises: (1) a lubricating metal and alloy thereof, lubricating metal chalcogenide, halide, carbonate, silicate or phosphate, or a particulate lubricating metal nitride, or a carbon lubricant; or (2) a silicate ester, polyphenyl ether, organic phosphate, biphenyl, phenanthrene, or phthalocyanine compound; (3) said material for lubricating a surface optionally containing a lubricant comprising an organic lubricant, inorganic lubricant, or a lubricant additive; (4) or mixtures thereof. 13. The method of claim 12 wherein said organic lubricant comprises a petroleum lubricant, synthetic lubricant, grease, or solid lubricant, or combinations thereof, and said additive comprises a detergent or a dispersant. 14. The method of claim 13 wherein said superabsorbent polymer is neutralized or cross-linked, and is based on acrylic acid, acrylamide, or an acrylate. 15. The method of claim 12 wherein said superabsorbent polymer is neutralized or cross-linked, and is based on acrylic acid, acrylamide, or an acrylate. 16. The method of claim 12 wherein said organic lubricant comprises a petroleum oil, an organic ester, a silicone, or a glycol, and combinations thereof. 17. The method of claim 12 wherein said substrate comprises a cable. 18. The method of claim 12 wherein said substrate comprises a wire. 19. The method of claim 12 wherein the particle size of the superabsorbent polymer comprises from about less than 0.5 microns to about 300 microns. 20. The method of any one of claims 12-18 and 19 wherein said composition is a product produced by the process of combining said superabsorbent polymer with said material for lubricating a surface. 21. The substrate of one of claims 1 or 12 wherein said: (1) lubricating metal and alloy thereof, lubricating metal chalcogenide halide, carbonate, silicate or phosphate, or a particulate lubricating metal nitride, or a carbon lubricant comprises; molybdenum disulfide, cobalt chloride, antimony oxide, niobium selenide, tungsten disulfide, boron nitride, silver sulfate, cadmium chloride, cadmium iodide, cadmium oxide, borax, basic white lead, lead carbonate, lead monoxide, lead iodide, asbestos, talc, mica, zinc oxide, zinc phosphate, iron phosphate, manganese phosphate, carbon, graphite, babbitt, bronze, brass, aluminum, gallium, indium, thallium, thorium, copper, silver, gold, mercury, lead, tin, indium, or the Group VIII noble metals or mixtures thereof.
