Use of fluorinated polymers based on fluoropolyethers for the preparation of crosslinkable high dry formulations comprising a fluorinated part RF and optionally an hydrogenated part RH, not containing groups capable of linking by means of hydrogen bonds to basic acceptors, an hydrogenated part Rh1 and Rh2, wherein Rh1 is equal to or different from Rh2, and Rh1 and/or Rh2 being linking bonds containing at least a functional group capable of linking by means of hydrogen bonds with basic acceptors, the bonds joining the fluorinated part to the hydrogenated part being of ether C-O simple type, the terminals T'a and T'' being such as to render the structure mono-, bi- or polyfunctional, and subsequent crosslinking of the fluorinated polymer, the monofunctional products being always in admixture with a resin having even a higher functionality than the described type; the preferred fluorinated products have the formula: T''- (Rh2) y (RH) x -RF- (RH)x - (Rh1)y' T'a
