Cs0.33WO3 is prepared into dispersion at first. And then the transparent dispersion is applied for preparing heat insulating glass coating, which shields heat by absorbing heat radiation in the sunlight to save energy. And such a coating also shields most of the ultraviolet light and light pollution to reduce the harmful UV radiation and glare light. Now, Cs0.33WO3 heat insulating glass coating is attracting more and more attention due to its high heat shielding performance and environmental protection.

According to the experts, in the production of heat insulation coating, appropriate dispersant can keep colloidal Cs0.33WO3 dispersion stability through steric stabilization and electrostatic effect. And there is no doubt that PVA and titanate coupling agent have better dispersing effects than poly-carboxylic salt. Additionally, the optimal addition amount of dispersant was 2.5 wt% for PVA and titanate coupling agent, with which higher dispersion stability could be achieved.
