A method for obtaining self-cleaning and self-sanitizing surfaces of finished leather, comprising the steps of deposition of two coating layers containing respective active mixtures on the finished leather surface, in which a first active mixture comprises a film-forming compound based on polymers and filler, a flow additive compound, a cross-linking compound, an anti-oxidant compound and an aqueous dispersion, and a second active mixture comprises a water-based auxiliary flow additive compound, a silicone emulsion, a solvent aliphatic prepolymer, a photo-catalyst compound, a water repellent agent, a biocide action powder agent and solvent agents and/or wetting agents and/or dispersing agents and/or anti-foam agents.
Method for obtaining self-cleaning and self-sanitizing surfaces of finished leather, characterized in that said method comprises a first step of depositing a first coating layer of a first active mixture and a second step, subsequent to said first step, of depositing a second coating layer of a second active mixture, above said first layer, on the surface of said finished leather, wherein said first active mixture comprises a film-forming compound formed by polymer and filler, a flow additive, a cross-linking compound, an anti-oxidant compound and an aqueous dispersion, while said second active mixture comprises an auxiliary water-based flow additive compound, a silicone emulsion, a solvent aliphatic pre-polymer, a photo-catalyst compound, a water repellent agent, a powder formulation with a biocide action and solvent agents and/or wetting agents and/or dispersant agents and/or anti-foaming agents.
