High-performance self-cleaning coatings are coatings used for glass curtain walls and exterior walls of buildings. High-performance nano-TiO2 sol-gel film can decompose stains on glass surface or exterior wall coatings under sunlight. They enjoy features such as good weather resistance, easy use, maintenance-free, colorless and transparent. This product can help you to reduce your use cost of the building glass curtain wall by RMB 20 yuan per square meter, and can also effectively remove pollutants from the external walls of the building. Applying this product on glass surfaces will allow a high degree of visible sunlight transmission. This product can also improve the conversion efficiency and service life of photovoltaic cells. At present, we have grasped the technologies required for mass production and application of this eco-friendly high-performance nano-TiO2 self-cleaning coatings.
