Disclosed is a polyurethane based composition for treating textiles to provide such treated textile with oil, water or oil and water repellency. The composition comprises a polyfunctional liquid polyurethane-containing adduct wherein the adduct contains as a first functional group at least one structo- terminal blocked isocyanate moiety per molecule, and at least one second structo-terminal functional group per molecule which is a perfluoro or siloxane moiety.
Cette invention concerne une composition à base de polyuréthane utilisée pour traiter des textiles et leur conférer des propriétés telles que les textiles traités soient oléophobes, hydrofuges ou bien oléophobes et hydrofuges. La composition contient un produit d'addition contenant du polyuréthane liquide polyfonctionnel, ce produit d'addition comprenant comme premier groupe fonctionnel au moins une fraction isocyanate bloquée à terminaison structo par molécule et au moins un deuxième groupe fonctionnel à terminaison structo par molécule qui est une fraction perfluoro ou siloxane.
