Nano tungsten oxide may be used to prepare a new type of glass thermal insulation coating, which is a kind of transparent and energy-saving water-based coating of high heat insulation performance. It is reported that such coating has been widely used in heat-insulating and energy-saving upgrade of common transparent glass such as architectural glass, automotive glass and ship glass.

Nano yellow tungsten oxide may be used to prepare a new building material - glass thermal insulation coating, which integrates the advantages of high heat insulation, high heat preservation, high energy conservation, environmental protection and safety. So, such transparent coating is widely used in energy-saving renovation of existing buildings and new buildings, including glass windows of various commercial and civil buildings, floor-to-ceiling windows, glass doors and windows of large waiting rooms, exhibition halls and auto glass. It is relatively low in cost and easy to operate.

Nano WO3 is an extremely important raw material for the preparation of glass thermal insulation coating. The prepared heat insulation coating is a new type of transparent heat insulation coating for building glass, which integrates the advantages of high heat insulation, energy conservation and safety. So, such coating is widely praised by the construction industry and users.

Nano WO3 may be used to prepare a new type of smart window heat insulation coating. As we all know, for glass coating, the most important property is heat insulation effect. If the heat insulating effect is not qualified, environmental protection and energy conservation are empty talk.
