Hydrophilic as well as hydrophobic surfaces offer advantages for cleaning of technical surfaces. The following properties of hydrophilic coatings are interesting: less dirt, easy to clean, antifogging and inhibition of growth for vegetation and bacteria. Particularly the soiling of a transparent surface causes light scattering and lots of brilliancy. The good wettability by water (very thin water film, no formation of water drops) of hydrophilic coatings inhibits the scattering of light and prevents fogging on the surface. The resulting very glossy and clean surface reduces also the growth of microorganisms.
