Abstract: The molecule of the new urethanes contains an aliphatic fluoroalcohol, an isocyanate and an aromatic dihydroxy, diamino, aminohydroxy, aminocarboxy or hydroxycarboxy compound. They are prepared by reacting an aliphatic fluoroalcohol with a diisocyanate or triisocyanate to give the fluoroalcohol/isocyanate adduct and by reacting this adduct with said aromatic compound to give the desired urethanes composed of an aliphatic fluoroalcohol, an isocyanate and the bifunctional aromatic compound mentioned, and also be reacting a urethane of this type which also carries an active hydrogen atom on the bifunctional aromatic compound, with an isocyanate compound containing one or more isocyanate groups. The new urethanes are preferably used for imparting an oleophobic and hydrophobic finish to textiles and leather.

Abstract: The novel urethanes correspond to the formula I below in which a denotes a number from 5 to 17 and b denotes a number from 1 to 7. These urethanes are prepared by reacting the corresponding perfluoroalkylethanol/epichlorohydrin adducts with toluelene diisocyanates. The novel aqueous dispersions are essentially composed of the novel urethanes, cationic or betaine emulsifiers and non-ionic emulsifiers, water-insoluble carboxylic and/or dicarboxylic acid esters and alkanediols or polyalkanediols which can be etherified on one or both sides, in water. The novel urethanes and the novel aqueous dispersions are used to impart an oleophobic and hydrophobic finish to textiles, leather and furs. They are also suitable for the treatment of unpainted timber, for example unpainted furniture.

Abstract: The novel urethanes conform to the following formula I: where a is from 5 to 17 and b from 1 to 7. These urethanes are prepared by reacting the corresponding perfluoroalkylethanol-epichlorohydrin adducts with toluylene diisocyanates. The novel aqueous dispersions consist essentially of novel urethanes, cationic or betainic and nonionic emulsifiers, water-insoluble carboxylic and/or dicarboxylic esters and alkanediols or polyalkanediols, which may be etherified in either or both positions, in water. The novel urethanes and the novel aqueous dispersions are used for conferring oleophobic and hydrophobic properties on leather and furs.

Abstract: The novel urethanes are composed essentially of fluoroalcohol-isocyanate adducts as the fluoro component and a polysiloxane component, the two components being combined in a structurally specific manner. The novel urethanes are prepared by reacting the fluoroalcohol-isocyanate adducts with the polysiloxane in a molar ratio of 1 to 2:1 at a temperature of 30 DEG to 130 DEG C. The novel urethanes are preferably used for finishing textiles, to which they also impart the property of a soft handle in addition to good hydrophobicity and oleophobicity. They are also suitable for finishing leather, skins and wood.
