[0002] Polyurethane wire varnish is a high-performance coating, mainly used for insulation protection and aesthetic coating of electrical equipment. It is composed of polyurethane resin, pigment, solvent and additives, etc., and has excellent arc resistance, heat resistance, chemical corrosion resistance, wear resistance and aging resistance. Polyurethane wire varnish has good insulation performance and can effectively prevent leakage and electric shock accidents of electrical equipment. In addition, it can also prevent damage from ultraviolet rays and other external factors and extend the service life of the equipment. Its aesthetic performance is also very good, which can provide a neat and beautiful appearance for electrical equipment. Polyurethane wire varnish is usually applied by spraying, brushing or dipping. Before construction, the surface of the equipment needs to be cleaned and necessary surface treatment is performed. During the construction process, it is necessary to pay attention to controlling the thickness and uniformity of the coating to ensure the quality and performance of the coating. The quality of polyurethane wire varnish directly affects the insulation performance and service life of the equipment.
