Ammonium metatungstate dispersion plays the following roles in the coating industry:
- Enhance the performance of coatings
Enhance the heat insulation effect
The use of ammonium metatungstate prepared heat-insulating dispersion and acrylic glue and other materials made of nano-organic inorganic hybrid coatings, coated on the surface of polyester film, can form a high-performance heat-insulating film. This transparent nano-particle coating film not only provides high transmittance, but also effectively blocks infrared rays, thus achieving high light transmission and high thermal insulation. This is particularly important for coating applications that require good thermal insulation properties, such as films for greenhouses.
Improvement of coating stability
The uniform dispersion of ammonium metatungstate dispersion in the coating helps to improve the overall stability of the coating and prevent the pigment particles from settling and coalescing, thus ensuring that the coating maintains good performance in the process of use.
- Improve the optical properties of coatings
Maintaining high light transmittance
As mentioned before, the overall light transmittance of heat-insulating film containing ammonium metatungstate can be maintained at 60~80%, which is crucial for coating applications requiring good light transmittance, such as architectural glass and automobile windshields.
Enhanced light scattering
In certain coating applications, such as decorative coatings or special effect coatings, a certain level of light scattering is required to produce a specific visual effect. Ammonium metatungstate dispersion may scatter light through its particle structure, thus improving the optical properties of the coating.
III. As a functional additive
Weatherability enhancement
Ammonium metatungstate has high chemical and thermal stability, which makes coatings containing ammonium metatungstate maintain better performance in harsh environments, such as UV and oxidation resistance.
Catalytic effect
Ammonium metatungstate has reducing ability, and may be used as a catalyst to promote the curing reaction or cross-linking reaction of coatings in the preparation process of some specific coatings, so as to improve the performance of coatings.
Fourth, the expansion of application fields
Electronic industry
In the electronic industry, ammonium metatungstate dispersion can be used to produce precursors of tungsten film and interconnect, which is of great significance for the manufacture of microelectronic devices.
Aerospace industry
In the aerospace industry, Ammonium Metatungstate dispersion can be used to produce tungsten-based alloys and coatings to improve the high temperature resistance and wear resistance of aerospace devices.
Ammonium metatungstate dispersion has a wide range of application prospects and important roles in the coating industry. It can not only enhance the basic properties of coatings such as thermal insulation and stability, but also improve the optical properties of coatings and be used as functional additives. With the continuous progress of science and technology and the expansion of application fields, the role of ammonium metatungstate dispersion in the coating industry will be more prominent.
