Signo Nanocare’s Liquid Guard antimicrobial surface coating has been tested for its effectiveness against the SARS CoV-2 virus. This follows on from extensive testing on other enveloped viruses, such as TGEV Coronavirus and Influenza A.

“We are pleased to announce that the independent laboratory test proves that Liquid Guard delivers an additional level of hygiene between cleaning and disinfection cycles,” said Simon Mercer, MD, Signo-Nanocare UK.

Applying Liquid Guard to a surface actively neutralises viruses such as SARS CoV-2 along with other commonly found bacteria such as E.coli, MRSA, Streptococcus and Staphylococcus, among many others. This action is achieved through the creation of a layer of positively charged microscopic nano spikes, which attract negatively charged cell membranes. The cells’ outer wall is the ruptured, killing the cell and preventing it from replicating or being passed on from the surface through hand-surface-hand transfer, thereby reducing the spread of infections between families, colleagues and the wider community.

Liquid Guard antimicrobial surface coating permanently bonds to the substrate and becomes part of the surface for twelve months, as shown by abrasion tests that have been carried out to ISO 11998.

Field trials using adenosine triphosphate (ATP) testing have shown significant reductions in microbial colonies on treated high-touch surfaces, such as keyboards, door handles, desks and hand sanitiser pumps within offices and school environments, Signo says.

Liquid Guard does not replace regular cleaning, as this is still required to remove dirt, dust and debris from surfaces.
