Nano particle size cesium tungsten oxide, or cesium tungsten bronze nanopowder, can be said to be a transparent thermal insulation nanopowder as the heat insulating materials such as building thermal insulation coatings prepared by using the raw materials cesium tungsten oxide nanoparticles are mostly transparent such as water-based fluorocarbon resin transparent heat insulation coating.

According to experts, water-based fluorocarbon resin has very good weather resistance and durability. This is because F is the most electronegative element in the periodic table, and the atomic radius is second only to ammonia, and the C-H bond energy is 413KJ/mol. When H is replaced by F to form a C-F bond, the bond energy can be as high as 460KJ/mol. The C-F bond is hardly destroyed by heat, light, chemicals with low surface free energy. Also, it is difficult to be invaded by liquid. Among them, the Cs0.33WO3 transparent heat-insulation coating formulation using water-based fluorocarbon resin as a film-forming material: Cs0.33WO3 content is 1.2%, deionized water is 30%, dispersant is 0.4%, humectant is 0.1%, propylene glycol is 3%, the antifoaming agent is 0.37%, the fluorocarbon resin is 48.96%, the thickener is 1.5%, and the pH adjuster is 0.3%.
