Disclosed is a functionalized polyurethane resin containing a binder component (I), a hardener component (II) and, optionally, a formulation component (III). The binder component (I) consists essentially of urethane dispersions with defined structural components which, in turn, consist of special reaction products. Such polyurethane resins are used for the production of fluorine-modified polyurethane coatings and generally in construction or industrial applications for the permanent oil-, water- and dirt-resistant coating of mineral and non-mineral surfaces on the basis of, for example, hydraulically setting components.

L'invention concerne une résine de polyuréthanne fonctionnalisée comprenant un composant liant (I), un composant durcisseur (II) et, le cas échéant, un composant de formulation (III). En ce qui concerne le composant liant, il s'agit essentiellement de dispersions d'uréthanne à composants de structure définis qui sont constitués, par ailleurs, de produits de réaction spéciaux. Comme utilisation de telles résines de polyuréthanne, on mentionne la production de revêtements de polyuréthanne modifiés au fluor, ainsi que le domaine, en général de la construction et de l'industrie pour des revêtements permanents de protection contre l'huile, l'eau et les salissures, de surfaces minérales et non minérales à base, par exemple, de composants à prise hydraulique.
