ATOM photocatalyst has the ability to produce hydroxyl radicals with powerful oxidative power, which make it have the characteristics of antibacterial, sterilization, deodorization, hydrophilicity and self-purification, and become one of the most ideal environmental protection products.

ATOM photocatalyst is a catalyst that promotes or accelerates a chemical reaction without itself changing or destroying the bulk structure due to the chemical reaction.

After ATOM titanium dioxide (TiO2) absorbs ultraviolet rays from sunlight or lighting sources, it will produce hydroxyl radicals with strong oxidizing power such as O, O2, OH, etc.

Hydroxyl radicals can purify bacteria (organic substances) and odors (organic gases) to varying degrees. The super oxidative ability of ATOM titanium dioxide can destroy the cell membrane, make the bacteria in the body lose to death, coagulate the protein of the virus, inhibit the activity of the virus, and achieve the effect of killing the planktonic bacteria in the air. Experiments have shown that the air cleaned by titanium dioxide has a sterilization capacity of 99.99%.

Hong Kong is a narrow place, densely populated, heavily polluted, and the weather is hot and humid, which is particularly prone to breeding bacteria, causing respiratory diseases, asthma, allergic rhinitis and skin-related diseases. With the development of industry, environmental pollution has become more serious. While people are afraid of urban diseases, they are also afraid of using environmental cleaning products that generally contain harmful chemicals. Therefore, the use of nanotechnology - titanium dioxide (TiO2) coating called photocatalyst, began to be applied to the purification of the environment. Bring a safer and more natural clean life to human beings.

At present, most offices are sealed, and the central air conditioner is full of bacteria, the natural ventilation rate is low, and the indoor air quality is very poor. In addition, organic solvents in various decorative materials, such as carcinogenic PCB, DDT, PCDF, BHC, etc. Chlorinated biphenyls and organic chlorides, it is no wonder that urbanites have different degrees of allergies, which affect their health.

The Environmental Protection Department of the Hong Kong government pointed out that clean and fresh air compartments make drivers and passengers healthy and comfortable and have a pleasant journey. However, most vehicles in Hong Kong are now air-conditioned. Air pollutants in the cabin can build up and reach higher levels if the vehicle's air conditioning system is not properly maintained. Common air pollutants include: carbon monoxide (CO), nitrogen oxides (NOx), volatile organic compounds (VOC), smoke (or secondhand smoke), dust and mold.

Plus renovation works in commercial, residential buildings and public spaces are already commonplace. Improper construction can result in unpleasant odors and flying dust, thereby reducing the indoor air quality of the premises. Air pollutants generated during construction also spread from one floor to another. These can be avoided with some good work practices.

ATOM's photocatalyst can decompose indoor harmful substances into harmless water and carbon dioxide to achieve the effect of indoor purification. It is more effective than ordinary air purifiers, saves resources, and once applied, it is permanently effective.


Once the photocatalyst is applied, it can reach the hardness of H pencil, 6H or above. The hardened photocatalyst, if not deliberately worn (such as redecorating, peeling paint or replacing wall paper, etc.), usually does not separate from the titanium dioxide.
