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…
