Ionitec, a subsidiary of Surfaces Synergie Holding, has developed a new antimicrobial and self-cleaning coating called SaniUV. This coating is deposited by physical vapor deposition (PVD), and the process parameters for obtaining such efficiency are the subject of a patent.
Photocatalysis is a natural phenomenon in which a photocatalyst accelerates the speed of a chemical reaction under the action of light (natural or artificial). Using light energy, the photocatalyst generates the transformation of water and oxygen from the ambient air, generating highly reactive molecules called free radicals, which are able to break down organic substances (sometimes harmful), into completely harmless compounds by a redox reaction.
