Coating machine manufacturer takes you to understand what three proof paint is

What is three proof paint?

According to the requirements and emphasis of each region and manufacturer, there are various terms for three proof paint, such as three proof glue, moisture-proof glue, insulation glue, moisture-proof paint, protective paint, protective paint, covering glue, coating glue, waterproof glue, moisture-proof oil, three proof agent, protective agent, moisture-proof agent, conformal coating, conformal coating, and common coating. Three proof paint is a special formula coating used to protect circuit boards and related equipment from environmental erosion, thereby improving and extending their service life, ensuring safety and reliability of use.

In real-world environments such as chemistry, vibration, high dust, salt spray, humidity, and high temperature, circuit boards may experience corrosion, softening, deformation, mold, and other issues, leading to circuit failures. The three proof paint is applied to the surface of the circuit board to form a protective film (three proof refers to moisture resistance, salt spray resistance, and mold resistance). In situations such as chemical substances (such as fuel, coolant, etc.), vibration, moisture, salt spray, humidity, and high temperature, circuit boards without the use of three proof paint may be corroded, mold growth, and short circuits may occur, leading to circuit failures. The use of three proof paint can protect the circuit from damage, thereby improving the reliability of the circuit board, increasing its safety factor, and ensuring its service life. In addition, as the three proof paint can prevent leakage, it allows for higher power and closer spacing between printed boards. This can meet the purpose of miniaturizing components.
