    摘要: 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.
