Abstract: Use of fluorine containing polymers for the preparation of high dry formulations wherein the fluorine containing polymers are based on fluoropolyethers comprising a fluorine containing part RF and optionally an hydrogenated part RH, the bonds joining the fluorine containing part to the hydrogenated one being an ether —C—O—C—, bond the terminals T being such as to render the structure bi or polyfunctional, making thus possible the cross-linking reaction, the hydrogenated part RH not containing groups capable of linking by means of hydrogen bonds to basic acceptors.
