Tungsten trioxide may be applied to produce a nano transparent heat insulation coating, which can shield more than 98% of ultraviolet rays and block infrared rays of 60% or more. In addition, the new environmentally friendly thermal insulation coating has a visible light transmission rate of more than 70%. Moreover, the coating has high hardness, good scratch resistance and long service life.

What is important is that the tungsten oxide nano heat insulating coating is easy to construct. Such coating can be directly applied to the original glass without changing the glass, and does not affect daily life and work. Since the tungsten oxide powder used is a nano material, only a thin layer is required to ding as a heat insulating layer, and no seam will be formed. The seam is sometimes unavoidable during construction process of heat insulating film. If the construction effect is not satisfactory, it is easier to peel off and remove. And therefore such glass heat insulation coating is increasingly used in glass curtain walls, high-end hotels, hotels, office buildings, private houses, and exhibition halls, etc. And more important, it can be especially applied for the energy-saving renovation of old building glass.
