Johnson Group - 180 Days Self-Disinfecting Antimicrobial Coating Service

*Please note that upon placing your order, our customer service team will contact you within 2 working days to confirm the details and schedule of the service.*

BR Shield® 180 Days Self-Disinfecting Antimicrobial Coating is a reactive saline quaternary ammonium compound, which provides long-lasting antiviral and antimicrobial coatings to any surface it is applied to. The effectiveness can be assured for up to 180 days. This coating is specifically designed to greatly reduce the risk of cross contamination and the subsequent spread of pathogenic organisms from one person to another, with physical means rather than chemical means, making it much safer and durable.

Therefore, this method precludes the transfer of the SARS-CoV-2 viruses, or any other viruses.

Our professional team will carry out space disinfection first with SmellGREEN® Natural Cleaning Disinfectant, then apply the BR Shield® Antimicrobial Coating, let's limit the transmission of viruses and bacteria!

Seeing is Believing

BR Shield® have also conducted a simple visual ‘litmus test’ that demonstrates the difference between a treated and an untreated surface. The “seeing is believing” experiment visually proves the long-term efficacy of BR Shield®.

From the experiment, it can be clearly seen in the picture that the bread treated with BR Shield® Antimicrobial Coating has remained completely ‘mould free’ even after a period of more than 30 days.

How Does It Work?

The principle behind the coating is simple, the silane quaternary ammonium compound will be attached onto the surface with the help of electrostatic sprayer. Using the scientific principle that opposite charges attract each other, the positive charged liquid would then be attracted to the grounded or negative surface, allowing for a full and even coat of liquid on the surface.  Virus and bacteria are naturally negatively-charged, thus, the coating will attract them onto the surface due to the electromagnetic force induced, and destroy their membranes.

Frequently Asked Questions

1. Will regular cleaning a treated surface remove BR Shield® 180 Days Self-Disinfecting Antimicrobial Coating?

No! In fact, regular routine cleaning will only serve to enhance and optimize the efficacy of the treatment ensuring that the ongoing disinfection potential remains at maximum efficacy for at least 180 days.

2. Does BR Shield® 180 Days Self-Disinfecting Antimicrobial Coating cause mutation and adaptation in micro-organisms and the “super-bug” problem?

No. It is because the treatment destroys pathogens through physical means not by chemical poisoning, so there is NO possibility of any organism building up immunity.

3. What is the difference between BR Shield® 180 Days Self-Disinfecting Antimicrobial Coating protection and other antimicrobial solutions on the market?

There are two main discriminating characteristics that set BR Shield® 180 Days Self-Disinfecting Antimicrobial Coating apart and in a league of its own.

First, it is NOT a disinfectant based on highly corrosive or toxic chemical activity with a very short term period of efficacy. BR Shield® 180 Days Self-Disinfecting Antimicrobial Coating destroys pathogenic micro-organisms on contact using only a physical method of destruction.

Second, traditional disinfectant solutions are only effective for a very short period of time and once dry, their kill rate diminishes to zero very quickly. Because ‘BR Shield® 180 Days Self-Disinfecting Antimicrobial Coating’ works in a completely different way, by creating a very stable surface coating that destroys pathogenic organisms through physical contact rather than chemical poisoning.

These characteristics also mean that it can remain effective 24/7/365 for over 180 days following application, with safety ensured.

4. How do I know the BR Shield® 180 Days Self-Disinfecting Antimicrobial Coating treatment process is safe?

BR Shield® 180 Days Self-Disinfecting Antimicrobial Coating is fully certified and proven with lab reports to be 100% safe for use in any area where it might be applied.
