Active self-cleaning nanotechnology for the maintenance of highly transparent glass surfaces
SurfaShield G creates an invisible coating based on nanostructured titanium dioxide, which after application on the glass surface it increases the transparency and makes it self-cleaning, superhydrophilic and antistatic
SurfaShield G is a liquid formulation, for glass surface which creates a coating that absorbs surrounding light (ultraviolet), decomposes any pollutant and glass surfaces become self-cleaning. The glass transparency is not negatively changed, but is increased by 2% as nanoparticles reduce the local roughness of glass that would reﬂect light. Additionally, SurfaShield G acts as an antistatic preventing sand and dust accumulation. The action of the coating is enhanced by antifogging properties: Water cannot form droplets that scatter light and the fogging effect is prevented in high humidity/low temperature conditions. Due to these properties the application of SurfaShield G on photovoltaics increases the efficiency about 3-7% and the glass surface remains cleaner, without particles, dust or stains that affect negatively the PV efficiency.
APPLICATION SURFACESPhotovoltaics (PV), solar heaters
SurfaShield G application is realized by Tornador of Bendel GmbH. The application requires a portable air compressor. The appplication should be realized by specialized technicians to avoid optical coating defects. It has been measured that the time needed for the application is 2 minutes for every surface square meter. The total consumption rate of the product is 30 m2/L.
