Photocatalysis

How our sanitization works

Surfaces protected with ALTA^KEEM protocol perform a constant and continuous anti-microbial,  anti-bacterial and anti-fungi action all day long, lasting over 12 months after one single treatment.

Unlike conventional biocide products, that kill – at the time of application only – bacteria, viruses or molds, the photocatalytic coating constantly performs oxidation-reduction reactions that degrade them at molecular level, into harmless gaseous substances that are dispersed in the surrounding environment, not accumulating on the surface.

The decomposition of the bacteria takes place by means of the hydroxyl radicals (OH•) and the oxygen anions (O2-) generated by the photocatalytic process, which attack the lipid membrane of the bacteria, degrading it and preventing the aerobic respiration phase of the bacteria.
