Nano violet tungsten oxide coated glass is a heat insulating glass obtained by re-treating common glass by a glass coating method, wherein violet tungsten oxide is present on the glass substrate in the form of a thin coating layer. Such energy-saving glass is substantially transparent to visible light and is capable of shielding infrared radiation. Also, it is resistant to ultraviolet radiation.

Besides, the transparent coating layer of nano particle size tungsten oxide can also make common glass have stronger strength and hardness. Moreover, the glass can also be self-cleaning, waterproof, oil-proof, anti-fog and anti-icing. In addition, the coating film has excellent adhesion to the glass so that it is not prone to peeling and foaming. Therefore, such coating glass has long-lasting heat insulation and UV resistance. And therefore, tungsten oxide coated glass is more and more widely applied in energy saving reconstruction of building. And tungsten oxide is well known to many people.
