Conformal coating have protective properties such as moisture, salt spray, and mildew, thereby improving the reliability of the circuit board, increasing its safety factor, and extending the service life of electronic products. In order to meet the growing demand for high-quality conformal coating in the market, and at the same time solve the problems of high cost of imported conformal coating, environmental protection, safety and other problems, and better meet the production process needs of customers, our company's expert group and well-known university professors have jointly researched and developed a series of high-performance conformal adhesives for many years.






1. Product introduction

The company's LED moisture-curing tri-conformal adhesive is a one-component, high-solids, ultraviolet and moisture-cured modified polyurethane acrylate laminated product, which is coated on the surface of printed circuit boards (PCB circuit boards), electronic components, integrated circuits, etc., which can form a dense protective film and effectively protect various electronic components and soldering points. Its protective film has excellent chemical resistance, surface hardness, flexibility and moisture resistanceSex.

The LED moisture double-curing conformal adhesive developed by our company has a dual curing mechanism, using LED instead of UV curing, reducing costs, improving environmental protection requirements, and at the same time, the shielding part of the circuit board can also be completely cured by moisture. This series of LED conformal adhesives can be applied to printed circuit boards and components to reduce or eliminate electronic performance degradation when it may be affected by adverse operating environmental factors. The PCB circuit board with the use of conformal adhesive has the characteristics of moisture-proof, salt spray, and mildew resistance, as well as cold and heat shock resistance, aging resistance, radiation resistance, salt spray resistance, ozone corrosion resistance, vibration resistance, etc., so as to improve the reliability of the circuit board, increase its safety factor, and ensure its service life. In addition, because the conformal adhesive prevents leakage, it allows for higher power and closer printed board spacing, thus meeting the purpose of component miniaturization. It has the characteristics of fast drying, low odor, and environmental protection, which can effectively improve customer production efficiency and quality.

2. Scope of application

This series of conformal coating are suitable for the three-proof protection of electronic control boards such as computer products, solar energy, power supply products, communication products, televisions, audio equipment, household appliances, instrument equipment, medical equipment, new energy industry, rail transit, aerospace, military industry, etc., which can extend the life of the electronic control board and improve the stability of use.
