Nanometer yellow tungsten oxide for preparing heat insulation coating is a new type of nano heat insulation material with a particle size of 50~100nm and a purity higher than 99.95%. Such thermal insulation material has excellent thermal insulation performance, UV resistance and infrared resistance. In particular, it absorbs and reflects the near-infrared rays in the wavelength range of 800nm to 1000nm and the ultraviolet region below 380nm. Yellow tungsten oxide nanopowder is also a type of good ceramic colorant.
In such thermal insulation coating, the recommended dose of nano grain size yellow tungsten oxide powder should be based on the relevant application. For infrared attenuation of glass coatings, 3wt% to 8wt% is sufficient to achieve significant results. The optimum dose is generally determined by the thickness of the coating. For example, a thicker coating requires a lower dose, while a thinner coating requires a relatively higher dose. While it is also recommended that the user determines the optimal dose based on the relevant application before use.
