Tungsten trioxide powder, mainly WO3 nano powder, may be used to produce a building glass thermal insulation coating. That is to say, such building energy-saving coating is mainly prepared of tungsten trioxide nano composite ceramic material.

Nano WO3 may be used to prepare a functional building coating for use on glass, namely building glass thermal insulation coating. This new energy-saving coating may be applied directly to the surface of the glass to form a heat insulating film, which is transparent, heat-insulating and UV-blocking.

WO3 nanopowder may be applied to produce a transparent heat insulation coating, which is a new energy-saving and environmentally-friendly coating. Such thermal insulation coating has the following advantages:

Yellow tungsten oxide nanopowder may be used to produce a transparent heat insulation coating, which is suitable for the heat insulation and heat preservation of building glass or automotive glass. For example, apply this new environmentally-friendly thermal insulation coating to architectural glass, especially home glass.
