the plate will effectively make the dust and other pollutants swell in water and then take the dust in artesian process, so as t

After the top coat on the plate, applly a layer of hydrophilic coating, the coating by adding organic modified siloxane, polyethylene glycol ether copolymers, alkyl such as methyl as to control the coating surface water contact angle to be Q ≤ 5 °, rain contacted well with the plate, the plate will also effectively make the dust and other pollutants swell in water and then take the dust in artesian process, so as to achieve self-cleaning effect.
