摘要：The surfaces of stony materials, tiles, cement conglomerates and related manufactured articles are protected from the action of atmospheric agents and pollutants by applying onto said surfaces a protective material comprising a mixture of a vinylidene fluoride homo- 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 certain (per)fluoropolyethers. Said mixtures are applied by conventional methods.
