Within a short time environmental contaminants make surfaces look dirty and generate significant maintenance costs.
Even small amounts of water are enough to wash dirt particles away from the superhydrophilic surface.
A MECOPROTECT® coated surface can be easily cleaned and remains considerably cleaner if exposed to rain.
The titanium dioxide contained in the coating not only contributes to cleaning the surface, but also is capable of eliminating harmful substances from the air we breathe. TiO2 is a semiconductor. UV light generates electrons on the surface, which then form oxygen radicals. Oxygen radicals break down many harmful pollutants in the air: nitrogen into harmless nitrate, volatile organic compounds into CO2 and water and ozone decomposes into oxygen.
Under the effect of sunlight, the titanium dioxide photocatalytic coating MECOPROTECT® acts as a catalyst and causes decomposition of organic dirt particles. The TiO2 coating is easy to clean and even has self-cleaning properties if directly exposed to rain.
Surfaces coated with MECOPROTECT ® require considerably less cleaning if the surface is exposed to rain. Should any dirt adhere to surfaces, small amount of water is generally sufficient to remove it. Surfaces treated with MECOPROTECT® not only stay clean longer, but also make a significant contribution to reducing the maintenance costs of building.
Titanium dioxide is completely safe and environmentally friendly. It is widely used in medical and cosmetic applications, even in toothpaste. The photocatalytic process is continuous and remains undiminished by UV light. The product does not release any nanoparticles. The use and processing of MECOPROTECT® coated strips is completely safe.
UV light activates the MECOPROTECT® coating. The activation takes place within a few days of outdoor exposure. Indoor exposure will not activate the coating.
Once the coating has been activated the surface becomes hydrophilic. The water is then distributed evenly over the surface in a thin film. As a result, the coating dries very quickly without leaving any drop marks.
