Nano yellow tungsten oxide may be used to prepare a transparent glass heat insulation coating, which combines various functions such as high heat insulation, UV resistance, acid resistance, alkali resistance and scratch resistance. Also, such coating is waterproof, moisture proof, antibacterial and mildew proof. So, it is usually applied to architectural glass for heat insulation and energy conservation.

Nano tungsten trioxide may be used to prepare a transparent glass heat insulation coating, which is a full embodiment of nanotechnology. The transparent coating can shield infrared and ultraviolet while ensuring high transmission of visible light. That is, the coating can effectively shield solar heat radiation with high transparency. According to experts, such heat insulating glass coating may be applied to the surface of the glass with a thickness of only 5 microns, but have the same thermal insulation function as three layers of conventional glass.

Nano tungsten oxide may be used to prepare a transparent glass heat insulation coating. It is said that the insulating glass coating is derived from German military technology. And it is originally developed as a special insulation material developed to solve the problem of the high-impact cabin life-sustaining system caused by the high-speed cruising of the aircraft during high-speed cruising.

Tungsten oxide nanopowder is an important raw material for the preparation of nano transparent heat insulation coating. Such heat-insulating coating may be applied to the building glass of a thickness of several micrometers, and the indoor and outdoor temperature difference can reach about 6°C, the infrared shielding rate is over 70%, the visible light transmittance is higher than 70%, and the ultraviolet blocking reaches 99%. Therefore, in such an indoor environment, even if the air conditioner is not turned on, the effect of "warm winter and cool summer" can be achieved. So, how about the prospect of heat insulating nano coating?
