Three proof adhesive

Three proof adhesive, also known as circuit board protective adhesive or coating adhesive, is applied to the surface of the circuit board to form a thin film of a certain thickness, used to protect the circuit board and related equipment from corrosion in harsh environments. In situations such as containing chemicals (such as fuel, coolant, etc.), vibration, moisture, salt spray, humidity, and high temperature, circuit boards may be corroded, mold growth, and short circuits may occur, leading to circuit board failures. Three proof adhesive films can effectively protect circuits from chemical, moisture, and other contaminants, thereby improving the reliability of circuit boards, increasing their safety factor, and ensuring their service life. Three proof adhesive can be widely used as a protective coating for electronic components such as flexible and rigid circuit boards, aviation instruments, computer control boards, industrial control boards, semiconductor crystal circuit protection, home appliance controllers, and various circuits.
