Electrostatic spray is to use solid powder solvent instead of the liquid form, the high voltage makes powder coating negatively charged, With the help of electrostatic attraction, it is adsorbed on the surface of the workpiece to be coated, it is the coating method obtained after being heated and melted (or cured). Electrostatic spray is a new technology, what the powder coating we used does not contain a solvent and a dispersion medium and other liquid ingredients, when we use it, there is no need of dilution and adjusting the viscosity, itself can not flow, after melting it can flow, it will not like a liquid coating adhered to the surface of the workpiece. Therefore, electrostatic spray coating has the features of high efficiency, excellent film properties, solvent evaporation, little environmental pollution, energy consumption less, simple process, short production cycle, low cost, easy to paint automation etc..
FIPFG coating process can be directly coating the surface of the electrostatic spray products, to be closely integrated with the coating surface with a high degree of protection, good adhesion, anti-aging performance advantages. However, if the powder contains a small amount of PTFE and wax wrinkle agent, it will significantly affect the adhesion of the strip, therefore, we should pay close attention. At present, the technology has been widely used by the electrical industry.
