Problems solved by technology

At present, conductive ink is used as a coating for conductive heat generation and is generally used below 200 degrees, and even if the conductive heat generation coating is used below 200 degrees, there are many shortcomings, such as easy to fall off, the heat resistance of the adhesive is not strong, and local spots are easy. Burning, easy oxidation of conductive fillers, and frequent cracks in the coating structure lead to deterioration of the coating during use. Although a series of improvements have been made in recent years, there has been no improvement in the high temperature resistance and aging resistance of the coating. Significant progress has been made, and the demand for conductive and heating coatings with good performance, high temperature resistance and low cost in the market is the future trend
