MEDICOAT: “Coat and Forget” Photocatalytic Nano-Coating Technology Gives Antimicrobial Coverage
CIRCULUS, CO., Ltd. has developed a revolutionary new technology called MEDICOAT that allows for round the clock antimicrobial coverage without daily maintenance. This so-called “coat and forget" technology provides enhanced sustainable antimicrobial defense at a much lower cost to business owners. MEDICOAT de-activates the influenza virus in just 15 seconds, and it also neutralizes Staphylococcus aureus, E. Coli, and Bacillus subtilis. One test carried out in a major international airport in Japan found that MEDICOAT-treated surfaces resulted in a greatly reduced bacterial presence when compared with non-treated surfaces. This result was even detected 28 months after initial application.
CIRCULUS will train clients on how to properly apply MEDICOAT, with local staff and technicians taking specialist training on MEDICOAT detection techniques to ensure quality control. It is billed as a benefit to local businesses and communities in both a public health and economic initiative.
I. Easy and effective
It can be applied directly onto anything from luggage racks to restrooms to information desks. It can either be sprayed or applied using a cloth to affected areas, such as door knobs. The nano-sized filler particles can seal micron-sized fissures that are undetectable to the naked eye, and a standard surface resistance meter can be used to make sure the surface has been adequately coated.
II. Proactive solution to communicable disease
A lot of money is spent on reactive solutions for hospital-acquired infections and communicable disease in public. However MEDICOAT can be a proactive solution to these threats. It also lowers the cost for facility managers, who don’t have to face large costs for hiring 24/7 decontamination specialists.
・Antimicrobial coverage without daily maintenance
”Coat and forget” technology provides round-the-clock antimicrobial coverage without the need for
daily maintenance activities. This translates into an enhanced sustainable antimicrobial defense
system with significant cost-reduction benefits to business owners
・Solution for combating Hospital Acquired Infections (HAI)
Billions of dollars are spent each year on various strategies in response to hospital acquired
infections (HAI) that are reactive, and not proactive, in nature. In contrast, MEDICOAT provides a
solution for combating HAI grounded upon the solid notion of preventive strategies.
・Defense against transmission of communicable disease in public places
Major airports and hubs for mass transit systems (e.g. train stations, bus depots, etc.) serve as
potent grounds for the spread of communicable disease. MEDICOAT acts as an active first line of
defense against the transmission of communicable disease without imposing upon facility managers
the monumental costs of hiring round-the-clock personnel tasked with decontamination efforts.
How to apply MEDICOAT (doorknob used as example):
While an ocean of photocatalytic coating materials exist on today’s market, CIRCULUS’s nano-coating offers the following competitive advantages:
・Photocatalytic seal by filling micron-sized fissures on surfaces
In order to maximize the utility of MEDICOAT’s physical and substance properties, our photocatalytic particles are specifically designed to a uniform size pattern of 1-10 nm. These nano-sized filler particles effectively seal micron-sized fissures on surfaces that are undetectable to the naked eye.
・Antibacterial protection under minimum/no light conditions
MEDICOAT is effective under both diurnal and nocturnal conditions. This is achieved via a unique blend of photocatalytic titanium dioxide (for daytime/light condition use) combined with silver and platinum nanoparticles to offer antibacterial protection under minimum/no light conditions.
・Detectable nano-coating with a standard (electrostatic) surface resistance meter
Nano-coating is invisible and cannot be observed without the aid of a microscope. Therefore, the task of confirming where a nano-coating material has been successfully applied is exceedingly difficult. In order to enhance the capability of clients to check for where the nano-coating has been applied, MEDICOAT has been specifically engineered to be detectable with a standard (electrostatic) surface resistance meter.
・Effectively inactivates the influenza virus in 15 seconds (third party testing carried out by Shokukanken Laboratory).
・Neutralizes Staphylococcus aureus, E. Coli, Bacillus subtilis (third party testing carried out by the Department of Environmental Sciences, University of Shizuoka, Japan).
・After coating various surfaces in a major international airport in Japan, the MEDICOAT treated surfaces had a significantly reduced bacterial load in comparison with non-treated surfaces even after 28 months from initial application (third party testing carried out by the Department of Environmental Sciences, University of Shizuoka, Japan).
