Abstract
Lubricating agent containing fluorinated urethanes Lubricants comprising fluorinated urethanes, prepared by reacting a) compounds of the formula 1 Rf—X-A-H (1) in which Rf denotes a perfluoroalkyl group having from 1 to 20, preferably from 4 to 16, carbon atoms, X denotes C2-C4 alkylene, —CON(R1)-Q- or —SO2N(R1)-Q-, R1 denotes hydrogen or C1-C4 alkyl, Q denotes C2-C4 alkylene, and A denotes —O—, —S— or —N(R1)—, or mixtures of compounds of the formula 1 with compounds of the formula 2 R—X-A-H (2) in which R denotes C1-C20 alkyl, preferably C4-C16 alkyl, and X and A are as defined for the formula (1), b) triisocyanates, and c) compounds having at least two active hydrogen atoms.
