Bacteria and viruses are organic compounds which can be decomposed by ARC-FLASH Photocatalyst. Through widely spraying onto indoor walls, ceilings and the inside of transportation vehicles, ARC-FLASH Photocatalyst can easily decontaminate environment and remove disease-carriers with a long-term effect. The Antimicrobial ability of ARC-FLASH Photocatalyst has been proved by repetitive tests from the Japanese-Health-Ministry-assigned inspection institutions. In Taiwan, according to the test report of Food Industry R&D Institution the sterilization rate of ARC-FLASH reaches 99.99%. So far, ARC-FLASH is the only Photocatalyst which has been approved by National Authority in Japan.

All the odor molecules are organic compounds. ARC-FLASH Photocatalyst has an oxidizing power even stronger than ozone, so it can easily deodorize smell pervading in public restrooms, smoking rooms, and other environments.
Besides, ARC-FLASH Photocatalyst will effectively decompose cancercausing substances such as hydrogen sulfide and sulfur dioxide from lighting cigarettes. Therefore, it can not only make the air fresher but also build a nicer and healthier environment for passive smokers and growing children.
The oxidation power of ARC-FLASH Photocatalyst can decompose bacteria and dirt into water and carbon dioxide. Besides, due to its super-hydrophilicity Photocatalyst can help to form a water layer penetrating under dirt to avoid dusts’ attachment thus to keep the surface of objects clean.

Growing mold on the surface of objects is the main reason for mildew, especially in a humid environment like Taiwan where the indoor closets and walls can easily get moldy. The superior Antimicrobial ability of ARCFLASH Photocatalyst can avoid bacteria multiplying and further inhibit molding along with the bad odor generated from mildew.

The main material of ARC-FLASH Photocatalyst is TiO2, which is a substance with high stability approved by F.D.A. US as a food additive. There is much food added TiO2 in the market and it is also extensively applied in cosmetics and sun blocks which indicates it is very safe to human bodies and of no side effects.
Similar with TiO2, Photocatalyst is harmless to health as well. When contacting with water and oxygen in the air, Photocatalyst will transfer them into superoxide anions and hydroxyl radicals to decompose organic matters. Yet the two oxidizing substances will not release to air and not be inhaled by humans, as a consequence, it will not cause any negative effects to human bodies.

Photocatalyst will be induced an oxidation-reduction reaction after light illumination, and this feature can be analogized to iron conductivity which is permanent and will not reduce its effect with the increase of reaction frequency or reaction time as long as long Photocatalyst stays on the surface of objects. Photocatayst is water insoluble after application, and will turn dry in less than 30 seconds. ARC-FLASH Photocatalyst will not be erased by touch after being dried, and its hardness could reach the maximum (pencil hardness 4H) in 10~14 days, which is even harder than the paint of automobiles. The layer will last long on the surfaces of objects and will not be damaged unless being rubbed with hard things like steels or being repainted.
