Abstract: A process for treating wood comprising at least partially penetrating it with a urethane- or acrylate-based fluoro-material. Also, wood produced by the process.

Abstract: Urethane compositions comprising (a) a first fluorochemical urethane polymer or oligomer comprising the reaction product of (1) one or more polyisocyanates and (2) one or more fluoroalcohols, and optionally (3) one or more other isocyanate-reactive materials, wherein the ratio of isocyanate to isocyanate-reactive groups is about 1 or less, i.e., Part A, and (b) a second urethane polymer or oligomer comprising the reaction product of (1) one or more diisocyanates, and (2) water, and optionally (3) one or more other isocyanate-reactive groups, wherein about 5 to about 95 mole percent of the isocyanate groups of the diisocyanate are reacted with the water, i.e., Part B, for imparting durable repellency to substrates.

Abstract: A carpet which comprises: a) a pile comprising a plurality of face yarns; b) a primary backing having two major surfaces, i.e., a face surface and a back surface, the face yarns being secured to the primary backing and extending from the face, surface thereof; and c) an impermeable hydrophobic barrier bonded to the primary backing. Substantially the entire surface of the portion of the face yarn which is not encased within at least one of the barrier or the backing is hydrophobic.
