Some experts use Cs0.32WO3 nanoparticles (cesium tungsten bronze nanoparticles) as dingal particles and epoxy resin as film-forming material to prepare transparent heat insulation coating. The visible light transmittance of the obtained thermal insulation coating is above 80%. And the acid and alkali resistance of such coating are in line with the construction industry standards.

Some experts use polyvinyl butyral (PVB) resin as a film-forming agent, and nano cesium tungsten bronze as a pigment filler to prepare nano heat insulating transparent coating. The coating was characterized by mechanical properties, optical properties and thermal insulation effects. The results show that the prepared PVB nano transparent thermal insulation coating has good thermal insulation effect and high visible light transmittance. The nano transparent thermal insulation coating of cesium tungsten bronze nano particles has a transmittance of more than 80% in the visible light region and the infrared shielding rate is over 90% in the near-infrared region.
