The inorganic coating materials industry has good development prospects and the demand for boehmite applications is high

Coating materials can be divided into organic materials and inorganic materials. Organic materials mainly include aramid and PVDF, which are mainly used in a few high-end fields; inorganic materials mainly include high-purity alumina and boehmite. Due to their outstanding performance and excellent price, Due to its advantages such as low technical barriers, it has been fully penetrated into the domestic market and its market share is relatively high, reaching about 92%.

Among inorganic coating materials, boehmite has more advantages in performance. It has lower hardness, weaker water absorption, lower energy consumption, environmental friendliness, and abundant raw materials. Therefore, it will replace high-purity alumina and its market penetration will continue. rising. Since the application of boehmite in batteries can improve safety performance and reduce production costs, the market penetration rate continues to increase, reaching about 45% in 2019, and is expected to reach more than 70% by 2026.

According to the “Research Report on Market Segment Demand and Development Opportunities of China’s Inorganic Coating Materials Industry from 2022 to 2027” released by the Industrial Research Center It shows that in the world, the boehmite market is highly concentrated. Germany’s Nabot and China’s One Stone have higher shipment volumes, with market shares reaching about 38% and 37% respectively. South Africa’s Sasso ranks third. Its market share is 11%. In China’s boehmite market, Yishitong Yaoyao leads the market share. Yishitong’s boehmite production capacity will reach 8,100 tons/year in 2020, and will reach 30,000 tons/year by 2022, further increasing market concentration.

Compared with boehmite, the market concentration of high-purity alumina is lower. Global high-purity alumina companies are mainly concentrated in Japan and China. Japan’s Sumitomo Chemical has a production capacity of 20,000 tons and occupies the high-end market. In addition, Orbite Alumina Elnc also uses a unique production process to produce products above 5N level. my country’s high-purity alumina production companies include Shanghai Yiming Materials, Jingrui New Materials, etc., with a 5N-grade high-purity alumina production capacity of about 5,000 tons. my country’s high-purity alumina industry started late. The current products are mainly 4N grade, and there are few manufacturers of 5N grade products.

Benefiting from the development of the power battery industry, the demand for inorganic coating material applications continues to rise, and the market size has grown accordingly, reaching about 500 million yuan in 2020. In the future, driven by the development of wearable devices, TWS headsets and other industries, the demand for inorganic coating materials applications will continue to grow. By 2026, the market demand for inorganic coating materials will reach about 160,000 tons, with a market size of 2.8 billion yuan.

Industry analysts said that the application of inorganic coating materials in the field of power batteries has the advantages of high cost performance and high safety, so the market The demand is high. Benefiting from the development of the power battery industry, the inorganic coating material industry has developed rapidly. There are two main types of inorganic coating materials: high-purity alumina and boehmite. Among them, boehmite has more advantages and has huge potential for future applications. However, the boehmite market is highly concentrated, and due to the high production technology threshold of high-purity alumina, there are fewer companies that can produce 5N-grade products.
