Nano yellow tungsten oxide is a type of functional nano material, more specifically, heat insulating nanoparticles, which can be dispersed into water or other solvent by a dispersion grinding technology to obtain a thermal insulating dispersion, and then made into a nano transparent heat insulating glass coating. Also, the transparent heat insulating glass coating can be obtained directly by adding yellow tungsten oxide nano particles into water-based coatings.

Nano transparent thermal insulation coating of yellow tungsten oxide powder has a good shielding effect on ultraviolet rays and near-infrared rays. Especially in the near-infrared region, the IR shielding performance of tungsten trioxide is better than ATO and ITO.

Nano tungsten trioxide may be used to prepare a nano transparent thermal insulation coating for architectural glass. The new type of heat-insulating coating is composed of the mixed slurry of tungsten trioxide nano powder of a particle diameter of 5-10nm and antimony tin oxide, a resin and a diluent. The thermal insulating coating of high anti-UV performance may be applied for building glass windows.

WO3 nanopowder may be used to prepare a new type of nano transparent thermal insulation coating, which is environmentally friendly and energy-saving. So, what should be paid attention to when using such transparent thermal insulation coating?
