Nano grain size cesium tungsten oxide, or nano grain size cesium tungsten bronze, may be used to prepare transparent heat insulation coating for architectural glass windows or automotive glass windows. Experts say that water-based polyurethane is a good choice for the preparation of transparent heat-insulation coatings of cesium tungsten bronze nanoparticles. There is also a large amount of literature on the preparation of transparent heat-insulating coatings using water-based polyurethane as a film-forming material. The coating has excellent heat insulation properties and high visible light transmittance.

Some experts have prepared Cs0.33WO3 transparent heat-insulating coatings using water-based polyurethane as a film-forming material. The obtained coating has an average transmittance of 75% in the visible light region, 73% in the infrared region, and 99% in the ultraviolet region. In addition, the coating of cesium tungsten bronze nanoparticles has water resistance, alkali resistance, and aging resistance. And it also has good mechanical properties and long service life.
