Disclosed is a functionalized polyurethane resin containing a binder component, a hardener component and, optionally, a formulation component. The binder component 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.
