The three anti-paint is a special formulation of coatings used to protect the circuit board and its related equipment from erosion of bad environment, so as to improve and extend their service life to ensure the safety and reliability of use. Three anti-paint coated on the outer of the circuit board, forming a layer of both light and flexible only 25-50 microns thick film. It can be in the case of vibration, moisture, salt spray, humidity and high temperature protection circuit from damage. The protective film can be formed by the three anti-paint effective isolation can protect the circuit from the chemicals, moisture, and other contaminants erosion, thereby improving the reliability of the circuit board, and to enhance their safety performance, and to guarantee its life. Because the three anti-paint to prevent leakage, allows for higher power and closer to printed circuit board spacing. Thus can meet the purpose of the miniaturization of components. Whether transparent or colored three anti-paint can improve the appearance of the printed circuit board, and the latter by the cover components and design layout also ensure a higher degree of confidentiality. The three anti-paint has good transparency, strong adhesion, good flexibility, fast curing and excellent weather resistance and excellent electrical properties. As one-component room temperature curing resin, is extremely convenient to use, and good insulation properties. Glue cured to form an elastic rubber layer, with dust-proof, waterproof, moisture-proof, shock-proof, anti-surface aging, leak-proof electric -60-200 ℃ under the conditions of long-term work. Primarily as moisture, insulation, anti-sticking, isolation and other purposes. Typical uses: (1) consumers are increasingly concerned about the quality and reliability of the products, and electronic devices are more widely used in daily life, the use of three anti-paint manufacturers can improve product quality, reduce expensive warranty period fault costs. ② civilian and commercial applications of the three anti-paint can provide protection for household appliances in the electronic circuit, so that they can withstand water and detergent; humidity; chemicals in the environment; harmful substances in the office and home; adverse external environment. ③ the automotive industry, the automotive industry require three anti-paint protection circuit against following hazards: gasoline evaporation matter, salt spray / brake fluid. ④ electronic systems in automotive applications is growing rapidly, and therefore the use of three anti-paint automotive electronic devices for long-term reliability of the basic requirements. The ⑤ hood (such as: the engine management system) ⑥ passenger compartment (such as: computer control system of the car) ⑦ aerospace environment for electronic equipment pressurized rapid decompression, affect the performance of the circuit, there are strict requirements, it must be widely the use of three anti-paint. ⑧ pressure, vacuum the area: vacuum (such as: flight line control system); cabin (such as: air-conditioning systems); sailing both fresh water and salty seawater ship electrical wiring and equipment hazards. Using the three anti-paint can maximize the protection of the equipment on the water and, while immersed in the underwater equipment, the use of a resin to be protected is almost essential. ⑨ three anti-paint protection equipment from the erosion of the adverse external environment. Their very broad range of applications, further comprising: a tool (in favor of the storage of agricultural machinery, fertilizer and yard waste to prevent corrosion, to ensure the continued stability.
