Three-proof coating material

Conformal coating is a high-polymer insulating coating material. Applied to the surface of a printed circuit board (PCB), it forms a very thin protective film. This protects the PCB and components from electrochemical corrosion and short circuits caused by moisture, salt spray, sulfides, mildew, etc. It also provides resistance to vibration and high and low temperature shock, improving the stability of the PCB, increasing its safety factor, and extending its service life.
