Zusammenfassung:The present invention relates to a product specifically designed to coat porous textile and ceramic materials, which provides the material with a combination of hydrophobic properties and which can also be reversed, in response to variations in pH or the presence of transition metal cations, by means of a mechanism of induced hydrophilia that generates oil repellence upon contact with water, thereby facilitating the removal of any stain deposited on the surface of the material, while maintaining a protective effect against water and water-soluble agents. The product is also designed to reduce bioreceptivity by means of subsequent treatment with metal cations with proven biocidal effect, and to be used in other potential applications such as the generation of filtering fabrics for the separation of water/oil mixtures.
