We collaborate, develop, commercialise, manufacture and license a range of patented antimicrobial surface solutions. We provide up to 99.99% reduction rates in bacteria, germs, fungi and antibiotic-resistant superbugs, including MRSA and E. coli.

How does KASTUS® technology work?

Our photo-catalytic (light-activated) technology is placed on glass or ceramic surfaces, and sinters into the surface during firing, providing permanent protection for the surface:

  • Optically clear

  • Super hard-wearing

  • Scratch, chemical and stain-resistant

It provides up to 99.99% reduction in Gram positive & negative bacteria e.g. Staphylococcus aureus (MRSA), E. coli & VRE.

Environmentally friendly (non-toxic) through its 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).

Provides low water absorption for surfaces, leading to increased 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 removal 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.
