BIOS Anti-Bacterial® does not require the presence of sunlight to provide 24/7 anti-bacterial protection.

For more information of BIOS Self-Cleaning®, which is more suitable for external facings (outdoor use), click here!

BIOS Anti-Bacterial is available in two forms:

BIOS Anti-Bacterial® (HYDROTECT®) – application on the surface

BIOS Anti-Bacterial® (GRANITOGRES®) – throughout the whole body and thickness of the tile


Elimination of Bacteria in the Environment

These are the 4 strains of bacteria that are present all around the world (especially in Singapore) that are mainly the cause of hospital related infections: Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Enterococcus faecalis.

Both versions of BIOS Anti-bacterial (HYDROTECT or GRANITOGRES) are effective in eliminating 99.9% of these 4 strains of bacteria.

Anti-bacterial tiles are often confused with Anti-microbial tiles. Anti-microbial tiles do not eliminate bacteria, but simply prevent bacterial growth on the surface of the tile. They therefore do not provide the protection that is required.

If you have read about BIOS Self-Cleaning, you would know that the HYDROTECT technology is about the breaking down of harmful substances through the reaction with sunlight and Titanium Dioxide (TiO2).

The BIOS Anti-Bacterial version is an enhanced version of the self-cleaning technology because it does not require sunlight to be effective. This is because BIOS Anti-Bacterial is not only equipped with Titanium Dioxide (requires sunlight), but active noble metals too that does not require sunlight for a reaction to be triggered.

Meaning to say, the noble metals are active in killing bacteria 24/7. On top of that, when natural or artificial light is introduced, the rate of bacterial elimination will be far greater. The amount of light needed for the anti-bacterial reaction to trigger is 0.25 mW/cm2 , which is equivalent to the ultraviolet intensity from just next to a window in daylight.

 

 

 

 


BIOS Anti-Bacterial® – GRANITOGRES®

 

Patented by Casalgrande Padana, BIOS Anti-Bacterial – GRANITOGRES was developed in partnership with the Department of Biomedical Science, Microbiology Section, of the University of Modena and Reggio Emilia.

This technology refers to a silver-based anti-bacterial treatment that allows the tile to eliminate bacteria with or without light.

The main difference of this technology compared to all other tiling anti-bacterial technologies in the world is that this treatment is applied throughout the body of the tiles. As a result, users can be rest assured that the anti-bacterial feature will not weaken or disappear over the course of time. That being said, BIOS Anti-Bacterial GRANITOGRES is the only anti-bacterial solution suitable for areas with high amounts of traffic.

BIOS Anti-Bacterial GRANITOGRES uses silver (a noble metal) as its active agent and has been tested and certified by world accredited agencies.
