One, three anti-paint Features 
 Three anti-paint (common film) is a specially formulated coating material used 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 sex. 
 Paint coating on the circuit board coated appearance, forming a layer of light and flexible thin film is only 25-50 microns thick. It may be in shock, moisture, salt spray, humidity and high temperature protection circuit from the case of damage. Paint to form a protective film coating can be effectively isolated and can protect the circuit from chemicals, moisture and other contaminants erosion, thereby enhancing the reliability of circuit boards to enhance their safety performance, and to ensure its service life. 
 Because the paint coating to prevent leakage, thus allowing for higher power and the more recent PCB spacing. Miniaturization of components to meet the purpose. No matter the color of a transparent or coated with paint can improve the appearance of printed circuit board, while the latter also covered components and design layout to ensure a higher degree of confidentiality. 
 Good paint coating is transparent, strong adhesion, good flexibility, fast curing and excellent weather resistance and excellent electrical performance. For the one-component room temperature curing resin, extremely convenient to use, good insulation properties. Form elastic glue layer after curing, with dust, water, moisture, shock, anti-surface aging, leakage power and so on, can be -60-200 ℃ under the conditions of long-term work. Primarily as a moisture-proof, insulation, anti-sticking, isolation purposes. 
 Two, three anti-paint Typical use: 
 ① Now consumers increasingly concerned about product quality and reliability, and electronic devices have also been more widely used in daily life, the use of coating paint manufacturers can improve product quality, reduce costly warranty costs of failure. 
 ② civil and commercial applications for home appliances in the paint coating of electronic circuit protection, so that they can withstand water and detergent; humidity; chemical environment; office and harmful substances in the home; adverse external environment. 
 ③ the automotive industry, automotive industry requires protection circuit coated paint hazards from the following situations, such as: gasoline evaporation materials, Fog / brake fluid and so on. 
 ④ electronic systems in automotive applications in the rapidly growing, the use of lacquer coating to ensure the car has become a long-term reliability of electronic devices, the basic requirements. 
 ⑤ machine under the hood (such as: engine management system) 
 ⑥ passenger compartment (eg: car, computer control system) 
 ⑦ aerospace electronic equipment, pressurized environment, decompression speed, affect the performance of the circuit, there are strict requirements, it must be widely used coating paint. 
 ⑧ compression and decompression area: decompression (such as: flight line control system); local storage (such as: air-conditioning systems); navigation both fresh water and salt water marine equipment are electrical lines will cause harm. Paint coating can be used to maximize the protection of water facilities, and equipment for the immersion in water, the use of resin to protect is almost essential. 
 ⑨ coated paint protection equipment from the erosion of external environment. Very broad range of applications, including: Tools (in favor of storage of agricultural machinery, fertilizers and yard to prevent the corrosion of waste, to ensure continued stability.
