Tungsten trioxide nanopowder may be used to produce a new type of transparent heat insulation glass coating, and then be applied to architectural glass curtain walls. The glass heat-insulating coating has obvious heat-insulating effect, strong ultraviolet resistance and high adhesion to the substrate. Also, such coating has good corrosion resistance to acid, alkali, salt fog and seawater. Besides, it is anti-aging to form a dense coating film.

Furthermore, the energy-saving coating of tungsten oxide nano particles can effectively shield the heat radiation energy (infrared rays) in the sunlight. That is to say, such coating can effectively reduce the radiation heat transfer and convective heat transfer to reduce the room temperature and improve safety of the environment. It is estimated that the energy saving rate of building can be increased by more than 15% after applying with such coating. In addition, this new environmentally friendly coating has a high UV shielding rate of 98% or more, which reduces the possibility of skin diseases such as skin cancer to some extent.
