Advanced Silver Ion Technology

The term antibacterial refers to a substance that inhibits the growth of microorganisms. Our optional antibacterial powder coatings* incorporate an advanced silver ion technology proven to actively reduce the growth of harmful bacteria on a painted luminaire’s surface. The silver ions in our antibacterial paint coatings effectively surround a bacterial cell. This stops it from dividing and prevents the cell from breathing – effectively killing the bacteria. Persistence tests have shown that our antibacterial paint does not decay over time

Effectiveness of Our Antibacterial Paint

Our optional antibacterial powder coatings reduce the growth of harmful bacteria on a painted luminaire’s surface, by up to 99.99% and up to 90% for Covid.

Test results

For SARS-COV-2 (Covid 19) = 90% after 6 hours (ISO 21702:2019). % relates to the reduction of the treated sample against the untreated/control sample. Viral strain tested = SARS-COV-2_COV2019 ITALY/INMI1.
For efficacy against MRSA and E.coli by up to 99.99% (ISO 22196:2011). See table below:

Species Contact Time Reduction Control
0 Hours 24 Hours Log 10 Percentage
P. aeruginosa 1.30E+04 <11.11 ≥ 4.39 ≥ 99.99%
E. aerogonese 1.50E+04 <11.11 ≥ 3.87 ≥ 99.99%
E. faecalis 2.80E+04 <11.11 ≥ 3.74 ≥ 99.99%
E. coli 1.90E+04 <11.11 ≥ 4.82 ≥ 99.99%
