The coating creates a microscopic and clear layer of silane molecules that adheres to any surface for a long time.

The positive charge of the silane molecules attracts the negatively charged viruses, bacterias and other microbes.

The long molecular chain or ‘sword’ part of the silane molecule punctures the lipid bilayer of enveloped viruses or in the case of bacteria, the cell membrane.

Once the envelope has been penetrated, the RNA (or DNA) of the microbe is exposed and destroyed, killing the microbe itself. 


A silane molecule is added to a conventional quaternary ammonium salt (combination also known as: Si-Quat, Quat-silane or Silane-Quat) and linked to a long molecular carbon chain. 

Additional bonding molecules (binders) lock the silane quaternary ammonium from its silane base, keeping the positively charged nitrogen and the long carbon chain (the ‘sword’) permanently in position.

The result is a highly active molecular layer with persistent bonding capacity and potent as well as durable antimicrobial properties.

"Keeping your practice a safe environment for patients is a difficult task given the frequency of disinfection that needs to be done on high contact areas, some of the chemicals used can also be abrasive to materials. Si-Quat offered us a long-lasting and durable surface treatment, it is easy to apply and adheres to almost any surface. This greatly reduces the need to disinfect high contact surface areas after each patient due to the antimicrobial properties of Si-Quat, we have kept our basic social distancing and hand washing policies in place and now feel more secure using Si-Quat in my practice."

"In a realistic “contagion-through-surfaces” scenario with a substantial lower viral load, liquid droplets containing SARS-CoV-2 are expected to dehydrate partially on surfaces, therefore, forcing the virus to interact with the coating. This dehydration-driven interaction is expected to increase the antiviral effect beyond the values reported by the experiment we performed based on ISO21702."

Does Si-Quat Kill COVID-19?

Yes. Studies on the effectiveness of Si-Quat with the coronavirus that causes COVID-19 (Sars-Cov-2), have been conducted by the University of Lisbon (Institute of Molecular Medicine) and the University of Ghent (Laboratory of Virology).

Tested to Standards BS EN1276, BS EN14476, BS EN 1650, EN 1040, ISO 18184, ISO 20743 and ISO 21702.

Due to its unique molecular shape and charge, Si-Quat is able to destroy enveloped coronaviruses like Sars-Cov-2.

The envelope around a coronavirus protects its RNA which it uses to reproduce itself when injecting it into a living cell. The RNA is a very fragile molecule; once the Sars-Cov-2 virus’ envelope is broken, its RNA is unable to remain intact and is destroyed. Without a protective envelope and enable to reproduce itself, the virus is eliminated.

Alternative Silane Quat products are not necessarily effective against 2019-nCoV, Novel Corona Virus.  Si-Quat by AFFIX Labs uses a unique binder system which increases its potency against COVID-19.
