A transparent protective film is formed on various printed circuit boards to prevent electric leakage and short circuit. It can prevent the erosion of weak
Suitable for isolate the contact between circuit board, wire, cable, wire connector, switch box, etc. and the external environment; It is used for TV to prevent corona caused by leakage of components such as high-voltage package; It can also be used to prevent electronic equipment such as communication signal antenna transmitting device from being eroded by moisture and salt fog.
