Technology from Japan

Chemical Name: CHARGE TRANSFER TYPE CATALYST
(JPO Patent No.: 3514702 2004.1.23; IPD Patent Ref: HK1116125)

Developed in Japan, CT Catalyst has the functions of decomposing carcinogenic VOCs, antibacterial, anti-mold, deodorizing and self-cleaning.
It has been imported from Japan with honorable awards and received great appreciations from the local government. It was being awarded with 2008 Yellow Ribbon Medal from Japanese Tenno, 2005 Thing Structure Japan Grand-Prix Prize for an Excellent Work from Japan Ministry of Economy, 2005 appreciated by Minister of Education, Culture, Sports, Science & Technology and 2004 29th Japan Invention Rewards.
CT Catalyst particles are as fine as 300nm diameter in average. By using CT Spray Coating Technique, the particles are evenly distributed on the surface of furniture, walls and every drawer as well, which allows them to fully perform in oxidation and reduction so as to eliminate the VOCs inside the flat rapidly.

Technology Used

At room temperature, the mobile charge of the CT Catalyst will perform repeated oxidation and reduction on the surrounding molecules.

Oxidation and Reduction

ACID-COOH+O2(+e)CO2+H2aO
ALKALINE-(OH)+H+ 2H2O(+e)

Functions of CT Catalyst
1. Decomposition of VOCs and Deodorization

There are various standards of IAQ among regions or districts. Roughly speaking, the standard of TVOC level is not more than 0.8mg/m3 or 1ppm. In the following table, you may find various IAQ index for reference.

In order to test the function of CT Catalyst, we carried out the “CT Catalyst Indoor Air Improvement Project” for the newly move-in unit, and recorded ideal results. The results (the orange part in the table) show that 72 hours after the completion of the CT Catalyst spraying, most of the VOCs have been reduced by 90% or more, and the effect is very significant.

The most noteworthy is that after using CT Catalyst for 72 hours, the removal rate of formaldehyde reached 99.4%. Compared with the 3-10 years required for natural decomposition, the efficacy of CT catalyst in removing formaldehyde is beyond doubt.

2. Anti-bacteria

A 24-hour sample test results show that CT Catalyst can control the growth of Escherichia coli, Staphylococcus Aureus, and MRSA within one day.

Japan Food Research Laboratories has tested the antibacterial ability of CT Catalyst in a 24-hour sample testing.
It conclusively confirms that CT Catalyst is able to control the growth of Staphylococcus Aureus, MRSA and Escherichia Coli within a day, in short, bacteria will be eliminated.
A study states that CT Catalyst affects the charge balance inside bacterial cells through charge transfer, making the environment impossible for bacterial growth.

3. Anti-mold

A control test result shows that, among the 6 test grids, 4 grids with CT Catalyst have no molds on the 15th day, while the other 2 grids without CT Catalyst have molds on the 4th day, and the mold becomes more severe on the 15th day.

Regarding the anti-mold performance of CT Catalyst, a controlled experiment is carried out. <br>The report indicated that CT Catalyst is able to stop the growth of mold, as the testing sample with CT Catalyst remains mold-free. It is because CT Catalyst is strongly water-repellent and separates moisture from the surface.
