Problems solved by technology

[0005] For some products such as equipment, electrical appliances, and electric vehicles that themselves also generate electromagnetic radiation, it is necessary to realize electromagnetic shielding and infrared shielding both internally and externally. Like this, the technical requirements for coatings are then higher. Among them, no metal composite protective coating has been found that can satisfy high light reflectivity, high electromagnetic wave absorption rate, high temperature and low temperature resistance, anti-corrosion and anti-aging, long service life and stable performance.
