In response to the Covid-19 crisis, we now offer our Touch⨁Point Clear Coat Service to assist in germ mitigation. This service is protects high volume architectural metal touch-points with a clear coat finish containing an antimicrobial additive of silver nanoparticles. The natural biocidal quality of the silver persists as long as the clear coat is intact. High volume touch-points include but are not limited to:
- Door Handles
- Security Turnstiles
- Security Desks
- Handicap Access Push Plates
- Elevator Call Button Panels
“The use of silver in medicine dates back thousands of years, and scientists have long known that the metal is a potent antibacterial agent.”1
The eerily titled article Silver turns bacteria into deadly zombies describes how ” … silver’s ‘zombie effect’ has gone unrecognized-until now. To uncover this grisly mechanism, scientists2 first killed a sample of the bacterium Pseudomonas aeruginosa using a solution of silver nitrate. Then, they carefully separated the dead bacteria from the silver solution. When they exposed living bacteria to the dead, they witnessed a microscopic massacre: Up to 99.99% of the living bacteria met their doom.“1
A recent study, authored by NASA scientists for the 48th International Conference on Environmental Systems, states “Silver ion is a proven broad spectrum biocide.”3
Used separately, or combined with the germ-killing Touch⨁Point Disinfectant Service4 , Stuart Dean’s Touch⨁Point Clear Coat Service offers added protection to touchpoint surfaces. Stuart Dean knows metal – and coatings. Stuart Dean’s disinfectant process4 will not degrade the finish applied with our Touch⨁Point Clear Coat Service.
We hope that you stay safe and healthy. Thank you for your continued trust in Stuart Dean.
