Recent studies have shown that the coronavirus is infectious on copper surfaces in a dry environment only for up to 4 hours. Copper also significantly reduces the infectivity of other viruses and bacteria particles on its surface, so it is also useful in reducing infections in general, epidemics and even hospital-acquired infections. For more information on the anti-infective properties of copper or copper foil, see the following pages:

The risk of infection can be significantly reduced on surfaces frequently affected by our self-adhesive copper foil:
- light switches
- push buttons (e.g. lifts)
- on the back of mobile phones
- hand-holds on laptops
- plastic or stainless steel door handles
- handrails, handles
