The three anti-paint is applied in those cases? Three anti-paint, also known as PCB electronic circuit board to protect the oil, drape oil, waterproof glue, moisture-proof paint, three anti-paint, anti-corrosion coatings, anti-salt spray paint, dust-proof paint to protect the paint, coating paint, three anti-plastic used three anti-paint PCB circuit board has a waterproof, moisture-proof, dust-proof, "three" performance and resistance to thermal shock resistance, aging resistance, radiation resistance, salt spray, ozone corrosion resistance, vibration resistance, good flexibility, attached forward to strong performance, therefore, is widely used. Initially the three anti-paint applied to the printed circuit board of the high-tech sector. Electronic devices are becoming more widely used in daily life, consumers are increasingly concerned about the quality and reliability of the product, using three anti-paint conformal coating enables manufacturers to improve product quality, reduce expensive warranty Use of Fault fees. Typical uses include the following range: 1, civil and commercial application of three anti-paint (conformal coating) to provide protection for household appliances in the electronic circuit, so they can withstand the: (1) water and detergent (washing machine, dishwasher, sanitary products, outdoor electronic LED screen), (2) the adverse external environment (display, anti-theft, fire alarm devices, etc.) (3) chemical substances in the environment (air conditioning, dryer) (4) in the office, and the families of harmful substances (computer , cooker) (5) all other circuit boards that require the protection of the three anti Automotive Industry automotive industry requirements of the three anti-paint protection circuit from the following hazards: gasoline evaporation matter, salt spray / brake fluid. Electronic systems in the car are growing rapidly, and therefore the use of three anti-paint automotive electronic devices for long-term reliability of the basic requirements. Aerospace strictly because of the special environment, aviation, aerospace and environmental requirements for electronic equipment, especially in the fast pressure, under reduced pressure, and still maintain the good performance of the circuit. The withstand voltage stability of the three anti-paint is so widely used. , Sailing either fresh water or salt seawater ship electrical wiring and equipment hazards. Maximize use of three anti-paint can protect the water and even submerged underwater equipment. 5, the medical three anti-paint can protect electronic equipment from external chemical and erosion of the special use of the environment to ensure its continued stability.
