A happy and healthy environment – with long term effectiveness.

In an interior coated with COAT, whenever the light is switched off toxins are absorbed by the apatite, and switching on the light causes a photocatalytic reaction with titanium oxide which results in the toxins being broken down into water and carbon dioxide through a process of oxidative decomposition, and removed.

New Technology - From Photocatalysis to “Artificial Light Catalysis”

Artificial Light Catalysis is a patented technology by which a reaction with artificial light - fluorescent light, LED, etc., removes toxins from the environment.
This technology enables the removal of bacteria, odors, and other contaminants with the same effectiveness as a photocatalyst, but can be applied indoors, in environments out of reach of natural sunlight.

Comparison of Technologies and Effectiveness

Photocatalysts: No visible light reaction – not effective indoors.
Visible Light Responsive Catalysts: Effectiveness limited by the range of the product.
Artificial Light Catalysts (COAT): Effectiveness even in indoor environments out of reach of sunlight.

Reassurance and Safety.

The main components of COAT (titanium oxide and apatite) are recognized as food additives.

An interior coated with COAT will be maintenance-free for 3-5 years for a typical room and 1-2 years for a vehicle interior. Actual results will depend on use of the environment.

Protection from air-borne infections and pandemics.

The benefits of COAT are not limited to simply having a clean environment.
It also offers protection against outbreaks of influenza, e. coli, etc.

Staphylococcus aureus (MRSA)

Staphylococcus aureus (MRSA)

Research Institute: Technology Research Institute of Osaka Prefecture

Measurements after 24 hours showed occurrence of Staphylococcus aureus had dropped to 0.

E. coli (O-157)

E. coli (O-157)

Research Institute: Technology Research Institute of Osaka Prefecture

Measurements after 24 hours showed Escherichia coli had fallen to a count of 60.

Influenza virus

Influenza virus

Photoirradiation condition: White fluorescent light (FL20SSW/18-B 18W)1000Lx
Research Institute: Japan Food Research Laboratories.

Influenza virus not detected in measurements after 24 hours.

Candida fungus

Candida fungus

Research Institute: Technology Research Institute of Osaka Prefecture.

Measurements after 24 hours showed Candida fungus had fallen to a count of 40.

Up to 181 times more effective than other products.

While there are similar products available, their effectiveness is nowhere near that of COAT.
With data from Environment Ministry standards, we compare COAT effectiveness in the removal of vehicle exhaust gas (Nitrogen Oxides) with roadside poplar trees.

Product Area

Equivalent in Poplars
(No. trees)
Company A, Product E 1,000 ※1.00μmol 34.6
Company T, Product E EX 1,000 0.052 95.0
Company T, Product H 150 0.057 15.0
Company K, Product F 1,000 - 25.0
Company S, Product D 160 0.077 21.0
Company D, Product S 200 ※0.56μmol 2.4
COAT 1,000 ※8.62μmol

* Calculated assuming a nitrogen oxide concentration of 1 ppm, and photocatalyst area of 0.005 sq. m. for 5 hours (JIS standard testing methodology).
Research Institute: General Incorporated Foundation of Japan Environmental Management & Technology Center (EMATEC)

The results show that COAT is more effective than other products by a factor of between 4.6 and 181.

Used in many facilities, both domestically, and overseas.

Quick to apply.

COAT is applied in 3 steps – Clean, coat, and fix.
For a 6 tatami room, application takes 3 – 5 hours. Over the following 25 days the product fixes completely, at which point the surfaces may be washed using any type of detergent without degradation.

STEP1 Clean
To ensure COAT fixes well, our staff perform a preparatory clean of the area.
STEP2 Coat
COAT is sprayed on using our special vaporizer.
After application, COAT is allowed to “fix” for approximately 25 days.
