1. Simple deposition method 2. Decomposes organic pollutants and protects the environment 3. Inhibits bacterial and fungal growth 4. Glass becomes superhydrophilic and antifogging, after minimal interaction with light 5. Glass surfaces become Self Cleaning and Self Sterilizing
By harnessing the surrounding light (natural or artificial), modified glass surfaces become self-cleaning: They decompose organic material and deactivate any living microorganism. SurfaShield coated surfaces can efficiently eliminate organic stains, bacteria, fungi, gaseous pollutants, even odours. Most importantly, dirt cannot adhere on the glass surface and dust is easily washed away. Light dependant devices, such as photovoltaics and solar heaters maintain their original efficiency with the self-cleaning of their glass surfaces. How is SurfaShield G applied on glass surfaces? HVLP (High Volume Low Pressure) spraying should be used as it combines both application simplicity and an ideal uniform functional coating. Two or three applications with a very thin layer are recommended. Follow the detailed application note, as described below. SurfaShield G is transparent, chemically inert and perfectly adheres on glass surfaces by chemically anchoring on the existing surface. Estimated consumption rate: 30-38 m²/L. How does it work? SurfaShield G makes the glass surfaces superhydrophilic and antifogging. Due to their nano-size, SurfaShield G nanoparticles absorb the available surrounding light energy (natural or artificial) and a series of physical phenomena takes place. In particular, a rearrangement of the surface hydroxyl groups that are hydrophilic (water-loving) is realized. Thus they reduce surface tension and the coating exhibits a super-hydrophilic character: Humidity and water droplets cannot stand on the SurfaShield G coated surface and dirt, dust and pollutants get washed away. Persistent organic pollutants get decomposed by the self-cleaning properties that SurfaShield G also exhibits.
