The localization process of my country’s three-proof adhesive (circuit board protective adhesive) market is accelerating, and silicone three-proof adhesive is its representative product.

Three-proof glue, also known as circuit board protective glue and coating glue, refers to a polymer fine composite coating material used to protect circuit boards and related equipment from harsh environmental erosion. Three-proof adhesive has three functions: salt spray resistance, moisture resistance and mildew resistance. It is widely used in automobile manufacturing, electronic and electrical appliances, medical equipment, rail transit, household appliances and other fields.

Based on different chemical compositions, three-proof adhesives can be divided into silicone three-proof adhesives, polyparaxylene three-proof adhesives, epoxy resin three-proof adhesives, acrylic resin three-proof adhesives, and polyurethane three-proof adhesives. Silicone three-proof adhesive is a representative product of three-proof adhesive. It is made of silicone modified resin as the base material. It is safe and reliable, can extend the service life of the product, is green and environmentally friendly, has good electrical insulation properties, is resistant to chemical corrosion, and is resistant to high/ With advantages such as low temperature, it can be used in flexible and rigid circuit boards.

According to the “2023-2028 China three-proof adhesive (circuit board protective adhesive) industry market in-depth research and development prospect forecast report》shows that three-proof adhesive is mainly used in automobile manufacturing, electronic and electrical appliances, medical equipment, rail transit, household appliances and other fields. In the field of automobile manufacturing, three-proof adhesive can be used to protect automobile circuit boards; in the electronic and electrical field, three-proof adhesive can be used to coat the surface of electronic components, and PCB circuit boards are its end products. In recent years, the development of my country’s semiconductor industry has accelerated, driving the demand for PCB circuit boards to become increasingly strong. In this context, as a protective material for PCB circuit boards, the industry’s development space continues to expand.

Major global manufacturers of conformal adhesives include Dow Corning, M-Momentive, HUMISEAL, Henkel of Germany, and Shin-Etsu Chemical Industries of Japan. Corporation (Shin-Etsu Chemical), etc. Ximi Chemical is the world’s leading three-proof adhesive company. It is affiliated to Chase Corporation of the United States. Its main products include silicone three-proof adhesive, acrylic resin three-proof adhesive and polyurethane three-proof adhesive.

The main manufacturers of three-proof adhesives in my country include Shanghai Kangda Chemical New Materials Co., Ltd., Chengdu Silicon Bao Technology Co., Ltd., Shenzhen Xinya Electronic Process Co., Ltd., Hubei Huitian New Materials Co., Ltd., etc. Compared with overseas developed countries, my country’s three-proof adhesive industry started late, but its development momentum is rapid and the market localization process is accelerating. The UV moisture dual-curing conformal adhesive independently developed by Kangda New Materials has the advantage of being green and environmentally friendly, and the products have been widely used in various circuits and electronic parts.

Industry analysts said that as a circuit protection material, three-proof adhesive has excellent performance and good prospects for industry development. As a representative product of three-proof adhesive, silicone three-proof adhesive has a wide range of applications and the market demand continues to grow, providing favorable conditions for the development of the three-proof adhesive industry. It is expected that in the future, as local companies continue to exert their efforts, the scale of my country’s three-proof adhesive market will further expand.
