摘要： A method of antibacterial and antiviral surface treatment of flexible cover sheet materials includes: providing a flexible cover sheet substrate; depositing at least one lower support layer on the upper surface of the substrate; providing an antibacterial and antiviral formulation comprising a liquid active sanitizing composition dispersed in a solvent containing a polymer-based solution; depositing the formulation on at least one lower support layer to form an upper antibacterial and antiviral active layer; heating the cover substrate to cause evaporation of the solvent of an upper active layer. The active sanitizing composition contains silver chloride and solid-state titanium dioxide of nanometric size and is intended, to inhibit proliferation of bacterial and viral pathogens on the surface of the substrate, while keeping the properties of the materials thereof unaltered.

摘要： 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.
