摘要:
A composition for imparting surface properties to substrates comprising a polymer of at least one polyurethane having at least one urea linkage prepared by: (i) reacting (a) at least one diisocyanate, polyisocyanate, or mixture thereof, having isocyanate groups, and (b) at least one fluorinated compound selected from the formula (I): Rf1-L-X (I) wherein Rf1 is a monovalent, partially or fully fluorinated, linear or branched, alkyl radical having 2 to 100 carbon atoms; optionally interrupted by 1 to 50 oxygen atoms; wherein the ratio of carbon atoms to oxygen atoms is at least 2:1 and no oxygen atoms are bonded to each other; L is a bond or a linear or branched divalent linking group having 1 to about 20 carbon atoms, said linking group optionally interrupted by 1 to about 4 hetero-radicals selected from the group consisting of —O—, —NR1—, —S—, —SO—, —SO2—, and —N(R1)C(O)— wherein R1 is H or C1 to C6 alkyl, and said linking group optionally substituted with CH2Cl; X is an isocyanate-reactive group selected from the group consisting of —OH, —N(R)H, and —SH; and thereafter (ii) reacting with (c) water and (d) 0.05 to about 2.0% by weight of an isocyanate-reactive fluorinated particulate component, based on a total dry weight of the composition.
