Harnessing the power of light and water, FN coated surfaces clean easily because the generated photo-oxidizers attract water molecules to its surface. Instead of forming droplets, water sheets, spreading to form a thin water film under dirt and oils. This remarkable and visible hydrophilic effect removes dirt and grime easily with a simple rain or water wash, reducing the need for harsh cleansers indoors and decreasing the frequency of costly exterior window and building surface cleaning. FN not only reduces organic contamination by oxidation, but also makes the surface virtually self-cleaning. Using water, a natural resource, for cleaning is ecofriendly and economical. FN works constantly to provide a more attractive and hygienic environment.
