Abstract
The invention relates to a composition for the protection of materials against contaminations, spots and stains. This liquid composition comprises by weight 0.1 to 1% of at least one fluorinated resin based on acrylic or methacrylic esters of fluorinated sulfonamido-alcohol, associated or not with non-fluorinated monomers, 0.4 to 10% of at least one adjuvant selected from aminoplast resins based on melamine, thermoplastic resins and waxes, and 89 to 99.5% of at least one organic solvent. Applied on materials such as walls, facades, monuments or sculptures in cement, bricks, concrete or stones and other construction elements, the composition according to the invention confers on the materials an excellent protection against natural or artificial contaminations.
