Nano tungsten trioxide may be applied to heat insulating window glass in the form of transparent thermal insulation coating. Thus, you can save money as it reducing the energy charge by lowering the room temperature in hot summer.
An aqueous photochromic material for vehicle thin film comprising different components with the following weight percentage: 25-30% of main photochromic material (tungstic acid, or phosphomolybdic acid, or a mixture of the two materials), 70-75% of auxiliary photochromic material (polyvinyl pyrrolidone) and water.
The thin film of automobile obtained by this preparation method has many advantages:
1. Environmental protection, and safety without any toxic effects;
2. With weather resistance and long service life;
3. Each performance index is excellent and reliable;
4. Good fluidity, easy mechanical construction, simple construction operation, and high construction efficiency;
5. Will not affect the performance of the window material, and not cause the secondary pollution of the environment.
