Abstract

Use of fluorinated polymers based on fluoropolyethers for the preparation of crosslinkable high dry formulations comprising a fluorinated part R.sub.F and optionally an hydrogenated part R.sub.H, not containing groups capable of linking by means of hydrogen bonds to basic acceptors, an hydrogenated part Rh.sub.1 and Rh.sub.2, wherein Rh.sub.1 is equal to or different from Rh.sub.2, and Rh.sub.1 and/or Rh.sub.2 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'.sub.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:
