Metals against Covid-19 – L’USINE NOUVELLE
The Covid-19 pandemic rekindled interest in the bactericidal and virucidal properties of certain metals, such as copper, zinc and silver.
The health crisis and concerns about transmission by contact (door handles, bars and transport grab handles, etc.) are highlighting the bactericidal and virucidal properties of certain metals, such as copper, zinc and silver.
In the Hérault region of France, MetalSkin Technologies produces composite coatings combining polymers and a 92% copper alloy for hospitals, construction sites and public transportation. Applications are possible on all contact surfaces: handles, ramps, taps, computer keyboards and mice, telephone housings, elevator buttons…
Edit of June 8, 2020: The laboratory Cemipai (Centre d’études des maladies infectieuses et pharmacologie anti-infectieuses), a CNRS / University of Montpellier unit, has found a 99.95% virucidal activity of MetalSkin® in four hours, under normal environmental conditions].
The English company Copper Clothing, the Israeli company Sonovia and the Chilean companies CoureTex, Copper 3D and The Copper Company offer masks and textiles impregnated or composed of zinc or copper. The virus survives only four hours on copper, compared to 24 hours on cardboard and two to three days on steel and plastics, according to recent studies.
