The bios.antibacterial ceramics slabs have antibacterial properties not only on the surface, but in the full mass. During the processing stages, to the ceramic material mineral particles are added, that generate a highly effective antibacterial reaction. A 99.9% reduction of the four main bacteria families can be achieved. The bactericide action generated by the process remains unchanged in time and no light is needed to enable it. In case of moisture, the performance is further strengthened. bios.antibacterialceramics is available in all the series of the Granitogres line by Casalgrande Padane. The ceramic elements may be supplied in their natural, polished and glazed versions, since the antibacterial particles are embedded in the core of the tile.
