Three anti-paint 
 1, three anti-paint, three anti-adhesive, moisture-proof plastic, insulated plastic, moisture-proof paint, protective paint, protective paint, coated plastic, coated plastic, waterproof plastic, moisture-proof oil, three anti-oil, moisture agent, conformal coating, deposited coating, conformal coating, coating common English name Conformal coating. Three anti-paint is a specially formulated coating to protect circuit boards and related equipment from the erosion of a bad environment to improve and extend their service life, ensure that the safety and reliability. 
 2, in real conditions, such as chemical, vibration, high dust, salt spray, humidity and high temperature environment, circuit board may cause corrosion, softening, deformation, mildew and other problems, leading to the circuit board failure. 
 3, three anti-paint coated on the surface of circuit board to form a protective film layer-three (three anti refers to the moisture, salt spray, mildew). It can contain chemicals such as (for example: fuel, coolant), vibration, moisture, salt spray, humidity and high temperature protection circuit from the case of damage. Under these conditions the circuit board may be corrosion, mold growth and produce a short circuit, resulting in paint is not used-three circuit failure, thereby improving the reliability of circuit boards to increase their safety factor, and to ensure its service life. In addition, because the three anti-paint to prevent leakage, thus allowing for higher power and the more recent PCB spacing. Miniaturization of components to meet the purpose.
