At KASTUS we collaborate, develop, commercialise, manufacture and license a range of unique patented and patent pending anti-microbial surface treatments and additives. We offer up to 99.97% kill rates against bacteria, fungi and antibiotic-resistant superbugs including MRSA and E. coli.

How does KASTUS technology work?

KASTUS Proprietary patent pending, photocatalytic (indoor light activated) technology is in line deposited on glass or ceramic surfaces becoming part of the top substrate as a permanent ceramic:

  • Optically clear

  • Super hard wearing

  • Scratch resistant surface

It provides up to 99.97% reduction in Gram positive & negative bacteria e.g. Staphylococcus aureus (MRSA), E. coli & VRE.

Environmentally friendly non-toxic & green (non-leaching of harmful chemicals or nano-metals into the environment) with no VOC.


Photo physical process (not specific to particular microbe type).

Catalytic mechanism (indefinite lifetime).

Durable and super hard ceramic coating.

Improves surface wettability offering increased potential for self-cleaning activity.

The Results

Performed at independent ISO accredited testing laboratories.

ISO 27447:2009 under visible light ‘Test method for antibacterial activity of semi-conducting photo-catalytic materials’. Shows the kill rate of bacteria offered by product. Results of Log 4-6 reduction (99.99%-99.9999%) of inoculated Staphylococcus aureus and E. coli bacteria on coated glass and ceramic.

ISO 11998:2006 - Scrub Resistance ‘Determination of wet-scrub resistance and cleanability of coatings’. Indicates that product is resistant to scrubbing over life time and that there is no change to coating properties.

ASTM D 2247 Humidity cabinet ensures that coating is not affected by wet conditions (100% relative humidity).

ISO 10545-13:1997 Chemical Resistance - Determination of chemical resistance of coating.

ISO 10545-14:1997 Staining Resistance - Determination of resistance to stains.
