Information about Photocatalytic Coatings
Photocatalysis is a completely natural process in which light-either sunlight or artificial indoor light-- hits a mineral and triggers a chemical reaction that breaks up or decomposes organic matter.
Sources of UV-A light include:
- Sunlight - UV-A light is abundantly present in direct sunlight, more than enough to power the full self-cleaning effect of Titanium Dioxide Coatings applied to the outside of buildings, fixtures and vehicles.
- Ambient Sunlight - On cloudy days, in the shade and in ambient sunlight through windows, there is also enough UV-A to trigger Titanium Dioxide Coatings's self-cleaning and odor-eliminating benefits.
- Fluorescent Light - Fluorescent lamps provide enough UV-A to make Titanium Dioxide Coatings coated surfaces very effective in eliminating odors indoors and helping to control the build up of grime.
Photocatalytic TiO2 (titanium dioxide - a common and naturally occurring mineral safely used in paints and cosmetics) has been extensively studied and used (in Asia and Europe) for its beneficial effects in medical environments (to create self-sanitizing surfaces), as a valuable new tool in air and water treatment, as the key to producing self-cleaning windows and even in the production of smog-eating cement.
It is well documented that light energized, photocatalytic TiO2 is a safe, non-toxic, anti-oxidant that produces hydroxyl radicals (OH-) that are remarkably effective in rapidly decomposing organic matter, including bacteria, fungi, odors and nicotine. This chemical process of photocatalysis actually converts organic matter into the harmless elements of water and carbon dioxide, which are then released into the air but in such minute quantities that their conversion is unnoticeable. The air we breath is full of water molecules but at such minute levels that we are not conscious of their presence. Moreover, because the process is a "catalytic" one, the chemistry of catalytic reactions means that the "ingredients" triggering these results are never used up in the process. Therefore, once applied to the specified surface (whether hotel room walls, carpets, upholstery or other soft good surfaces in casino areas, or HVAC ducting), the Seal n Lock Easy Seal products will continue to work, month after month.
