The power of photocatalytic activation
Over time organic substances and other environmental contaminants
deposit on surfaces, to which dirt and dust par ticles can then easily
adhere.
With the photocatalytically active MECOPROTECT® coating, organic
substances are decomposed under irradiation by UV(A) light and transformed
into carbon dioxide and water. Non-organic dirt particles adhering to coated
surfaces are thus minimized.
Environmental pollution
Within a short time environmental contaminants make surfaces look dirty, and generate significant maintenance costs.
Combats dirt with sunlight
MECOPROTECT® is a titanium dioxide photocatalytic coating. Under the effect of sunlight the TiO2 acts as a catalyst and causes decomposition of organic dirt particles. Indirect sunlight and limited moisture is sufficient to activate the self-cleaning process. The TiO2 coating has a self-cleaning effect even on surfaces which are not directly exposed to rain.
Continuous self-cleaning
Even small amounts of water, such as morning dew, are enough to wash dirt particles away from the superhydrophilic surface. A MECOPROTECT® coated surface cleans itself continuously and remains considerably cleaner over the long term.
Purifies air
The titanium dioxide contained in the coating not only contributes to cleaning the surface, but is also 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, ozone decomposes into oxygen.
Saves time and money
Surfaces coated with MECOPROTECT® require considerably less cleaning. Should any dirt still adhere to surfaces, rinsing with 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 buildings.
HIGHLIGHTS
Available in all colours
MECOPROTECT® is applied as an additional layer. The
thickness of the layer is no more than a few microns ;
it is almost transparent and applicable on any colour
or gloss. Strips coated with MECOPROTECT® have
excellent bending and roll-forming properties.
Activated by UV
UVA irradiation activates the MECOPROTECT®
coating. The activation takes place within a few
days of outdoor exposure. Indoor exposure will not
activate the coating.
Eco-friendly and sustainable
Titanium dioxide is completely safe and
environmentally friendly. TiO2 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
harmless.
Clean and dry
Once the coating has been activated the surface
becomes hydrophilic (attracts water). 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.
