Cesium tungsten bronze for preparing thermal insulation window film is a tungsten bronze in which electronic charge carriers are introduced by interstitial doping.

Nano cesium tungsten bronze is the optimal choice for producing heat insulating film, heat insulation coating, energy-saving glass or smart glass as a near-infrared absorber. And these transparent heat insulation products prepared show excellent selective optical transmittance in both the visible and near-infrared regions.

Cesium tungsten bronze is optimum for producing window thermal insulation film with high heat-shielding performance and high visible light transmittance. According to the experts, the composite layer-coated film can be prepared using a mixture of dispersed cesium tungsten bronze sol and acrylic UV-curing binder.

Cesium tungsten bronze is a new type of functional material that enables the prepared transparent glass coating to achieve the purpose of environmental protection, easy cleaning, high transparency, high heat shielding performance, energy-saving and emission reduction. Also, such a heat insulating coating is water-proofing, dust-proofing, fire-proofing and explosion-proof. Therefore, it can be widely used in building glass curtain walls (including shopping malls, office buildings, showrooms, etc.), smart homes, and portholes for aircraft.
