AGC Glass Europe has produced a coating for glass to help protect against Covid-19 contamination.
Respiratory droplets and aerosols contaminated with SARS-CoV-2 viral particles represent a risk of indirect transmission of Covid-19.
Infectious droplets on surfaces see their viral infectiousness decreasing with time, depending on the type of material and temperature.
A study published in the Coatings Journal with support from AGC was done on different materials ranging from metallic materials to float glass, acrylic glass and coated glass (Planibel Easy).
The result showed the time taken for the number of infectious viral particles to decrease, and demonstrates that SARS-CoV-2 viral particles stay active for a shorter time on Planibel Easy coated glass previously exposed to daylight (photocatalytic effect).
The study was carried out in an experimental setting that mimicked real-life conditions, under the responsibility of Prof. Muylkens of the University of Namur (Belgium) and confirmed by Prof. Lucet, Dr Visseaux and Dr Jérémie Guedj of INSERM / Assistance Publique-Hôpitaux de Paris (France).
The study used real human SARS-Co-2 viral particles at same concentration as the actual viral load observed in a cohort of patients infected with Covid-19.
The time needed to inactivate 90% of the SARS-Cov-2 viral particles is 37.5% shorter for Planibel Easy exposed to daylight than for float glass or acrylic glass. This means that using Planibel Easy greatly reduces the risk of viral transmission when we touch the surface.
Independently tested and certified, Planibel Easy has shown that when daylight activates the coating this accelerates the destruction of SARS-CoV-2 particles (the virus responsible for Covid-19) on its surface.
Planibel Easy can be combined in double glazing with other AGC products such as low-E glass. Resistant to corrosion and chemical damage, Planibel Easy can be delivered in toughened, laminated, bent and processed forms, and even in insulating double or triple glazing.
As long as the glass is exposed to daylight and/or UV(A) light there are plenty of possibilities to make your space a safer place.
