Transparent heat insulation coating of WO3 nanoparticles has good resistance to heat radiation (anti-infrared performance) with high anti-ultraviolet performance. So, such energy saving coating can be applied to architectural glass and other fields through spraying and other coating processes, which solves the disadvantages of traditional thermal insulation coatings with large haze and limited additive amount.

Certainly, the tungsten trioxide nano particles should be first prepared into highly transparent nano dispersion, and then added to a resin system to obtain a high-performance thermal insulation coating. Among them, the heat insulation nano dispersion is mixed with a resin or other material systems in an amount of 10% to 20%, and can be applied after being sufficiently stirred. This new type of environmentally-friendly thermal insulation coating can achieve energy-saving and cooling effect in the hot summer without affecting indoor lighting. In winter, it can achieve energy-saving and heat preservation effects. At the same time, it also protects indoor items, to slow down their aging and fading speed.
