Ecosolution

Ecosolution was designed to reduce nitrogen-oxide pollution in highly populated areas. Its secret lies in nano-particles of titanium dioxide and calcium carbonates, which bind with the base component of the paint. These particles absorb the base component of the paint. These particles absorb UV light and use it to convert nitrogen oxide into nitric acid, which is washed away when it rains. Ecosolution makes it possible to reduce nitrogen-oxide pollution in urban areas by 60%. When used on building facades, the effect lasts up to five years.
