ABSTRACT:
Formulations formed by aqueous dispersions of cationic ionomer fluorinated polyurethanes based on (per)fluoropolyethers, having end groups constituted by —NCO groups reacted with hydrogenactive compounds to give covalent bonds stable to water but thermolabile, usable for the surface hydro- and oil-repellent treatment of textiles.
