PROCESS FOR PROTECTING AND CONSOLIDATING STONY MATERIALS

摘要

The surfaces of stony materials, tiles, cement conglomerates and relevant manufactured articles are protected from atmospheric agents and pollutants by surface application of a protective material consisting of a mixture comprising a vinylidene fluoride polymer or copolymer containing 55-100% by moles of vinylidene fluoride, 0-45% by moles of hexafluoropropene and 0-30% by moles of tetrafluoroethylene and an aqueous microemulsion or emulsion of perfluoropolyethers. Such mixtures are applied by conventional methods onto the surface to be protected.
