Tungsten trioxide, mainly tungsten trioxide nanopowder, has very good heat insulation and UV protection dings. Therefore, tungsten trioxide nanoparticles with the properties of small particle size, uniform particles and easy dispersion is often prepared into dispersion. And then the dispersion is used to produce kitchen heat insulating glass coating.

The prepared smart coating has good transparency, so the coating film formed on the kitchen glass will also have good visible light transmission. As the tungsten trioxide kitchen heat insulating glass coating has a strong absorption effect on the near infrared wavelength near 900nm, it can make indoor temperature reduce 3-6 °C in the case of not opening the air conditioning. That is to say, such a thermal insulation coating will reduce unnecessary energy waste. Also, such coating is safe and environmental friendly as it does not contain toxic and harmful substances. Besides, the heat insulation coating has strong weather resistance and good thermal stability, so it will have long service life.
