Cs0.33WO3 particles, or cesium tungsten bronze particles, may be prepared into transparent heat-insulating coating, which may be used in architectural glass or automotive glass to obtain thermal insulating glass. Such glass has the advantages of heat insulation, energy saving and consumption reduction. And it is necessary to do the water resistance test, chemical resistance test and other tests of the Cs0.33WO3 coating. So, how to conduct a water resistance test?
According to GB/1733-(79)88 "Determination of Water Resistance of Paint Film", cesium tungsten bronze nano particles was used to prepare a transparent heat-insulating coating, and the coating was immersed in water and observed for 24 hours.

How to conduct chemical resistance tests? According to HG/T3828-2006 "Indoor Waterborne Wood Coatings", NaHCO3 solution and 50% ethanol were prepared at a concentration of 50g/L respectively; the solution was dropped on the transparent heat-insulating coating of nano grain size Cs0.33WO3 and placed for observation.
