Nano yellow tungsten oxide may be used to prepare a new smart glass coating – a transparent thermal insulation coating, which is mainly applied to building glass with excellent heat insulation effect. By spraying such environmentally-friendly thermal insulation nano-coating on the glass doors or glass windows, the obtained tungsten oxide heat insulation film has a thickness of 8-12um and a visible light transmittance of more than 85%. Therefore, the glass doors and windows of the house can be kept in a good visual appearance.

The heat-insulating glass coating of tungsten trioxide nano particles forms a protective film on the surface of the glass, which can shield more than 85% of infrared rays and can effectively shield the transmission of solar heat. In other words, such coating can shield the transfer of a certain amount of heat, thereby effectively achieving the desired effect of heat insulation. In recent years, China is gradually promoting the building energy-saving renovation plan, which is an opportunity for transparent heat insulation glass coatings such as tungsten trioxide heat-insulating coatings.
