Self-Cleaning Buildings Thanks to Nanotechnology and Green Chemistry

Toronto, Canada | Posted on July 31st, 2007

The photocatalyst coating is the combination of photocatalyst and nano technology. At the presence of light, the photocatalyst will decompose the organic pollutants. Without the adhesion of organic pollutant, the left inorganic pollutant on the surface can be easily swept away by rain. It is effective against organic-based dirt, mold, fungus, moss and protects substrate against UV discoloration.

Nanotechnology is the design and fabrication of objects with dimensions in nanometers, or billionths of a meter. Gens Nano is a water-based coating containing photocatalyst called Titanium dioxide ( TiO2 ). Titanium dioxide has been popular in the industry for many years. It is a natural mineral safe for human use. FDA approved TiO2 as a food color additive in 1966 with the stipulation that the additive was "not to exceed 1% by weight". Nano size titanium dioxide particles have photocatalyst power when exposed to light. This discovery was made by Japanese scientists in late 1990's and since then the photocatalyst technology has been proven commercially, making it perfect for development of advanced self-cleaning coatings.

Nano scale particles of titanium dioxide used in Gens Nano coating are synthesized, crystallized and dispersed directly in the water based solvent by means of proprietary advanced chemical hydrosynthesis technology, making the solution very stable and superior to similar products. Coating does not contain any VOC's (volatile organic compounds) making the product green, environment friendly and totally non-toxic to the environment.

Product Benefits:
- Keeps the building exterior clean for many years
- Protects the surface from dust, acid rain and air pollutant damage
- Purifies the air pollutant near and on the surface (e.g. car exhausts NOx, formaldehyde, benzene, VOCs)
- Decomposes the organic pollutant on the surface
- Reduces the energy consumption for cooling the building in summer
- Restrains from mildew or algae growth
- Fights the bacteria and virus on the surface and in the air near the coated building
- Absorbs the UV from sun and then protects the surface from UV damage
- Restrains the dust electrostatic absorption

(*) Photo-Catalysis is defined as "acceleration by the presence of a catalyst". A catalyst does not change in itself and is not consumed in the chemical reaction. This definition includes photosensitization, a process by which a photochemical alteration occurs in one molecular entity as a result of initial absorption of radiation by another molecular entity called the photosensitized. Chlorophyll in plants is a type of photocatalyst called photosynthesis. Photocatalysis is when chlorophyll captures sunlight to turn water and carbon dioxide into oxygen and glucose. Photocatalysis is the creation of a strong oxidation agent to breakdown any organic matter into carbon dioxide and water in the presence of the photocatalyst, light and water.
