The transparent coating of nano tungsten oxide has good optical properties, which can shield ultraviolet and infrared rays, that is, can effectively isolate solar heat radiation energy. The infrared shielding rate of the coating is 86%, the visible light transmittance is 80%, and the ultraviolet blocking reaches 99%. It needs only a few micrometers of thickness on the outdoor glass to make the indoor and outdoor temperature difference reach about 6°C. In addition, this new type of coating uses nano-inorganic material tungsten oxide, which is environmentally friendly with excellent resistance to aging and staining. Also, it is anti-static, anti-glare with long service life. In addition, in winter, such coating can increase the indoor temperature by more than 5°C.
