The solvent in the impregnating varnish has a swelling effect on the paint film to varying degrees, especially at higher temperatures.
During the use of the impregnated winding, the paint film may be thermally cracked due to heat, so the compatibility between the impregnated paint and enameled wire paint film has a great impact on the service life of motors, electrical appliances and meters.
During use, the winding may contact with various surrounding media, such as refrigerant in refrigeration equipment and various chemical gases in chemical plants. These media have different degrees of corrosion to the paint film, and salt fog can also produce chemical corrosion to enameled wires of electrical products on marine ships. Therefore, the paint film of enameled wires is required to have better chemical stability.
