Abstract
Surface portions of metal materials, in particular artifacts which are of interest from historical, artistic or archeological perspectives, are protected from atmospheric agents and pollutants, and are re-aggregated, by reversibly applying a protecting and aggregating material comprising a copolymer of vinylidene fluoride having 55-85 mol % of vinylidene fluoride, 10-45 mol % of hexafluoropropene and 0-30 mol % of tetrafluoroethylene. Such polymers are applied onto the surface to be protected as solutions in volatile solvents.
