The market demand for anti-rust pigments has been upgraded. Environmental protection, non-toxicity and high efficiency are its development directions.

Anti-rust pigment is a material that can delay or prevent chemical or electrochemical corrosion of metal. Anti-rust pigments are mainly used to prepare anti-rust primers. Their functions include preventing metal corrosion and improving the protective effect of paint films on metal surfaces. According to different mechanisms of action, anti-rust pigments can be divided into two categories: physical anti-rust and chemical anti-rust. Physical anti-rust pigments include iron oxide pigments, aluminum powder, mica iron oxide, etc. Chemical anti-rust pigments are divided into chemical corrosion inhibitors. There are two categories: type and electrochemical type. The subdivided products include lead anti-rust pigments, phosphate anti-rust pigments, etc.

Anti-rust pigments are widely used in engineering machinery, powder coatings, rail transit, automobiles, household appliances, steel structures, aerospace and other fields. In recent years, as environmental protection requirements have become increasingly stringent, the market’s requirements for the anti-rust properties, corrosion resistance, and environmental protection of anti-rust pigments have further increased. Against this background, anti-rust pigments containing heavy metals have gradually withdrawn from the market and are safe and non-toxic. , there is a demand for new and efficient anti-rust pigments, such as water-based anti-rust pigments, silica anti-rust pigments, composite anti-rust pigments, etc.

According to the “2023-2028 China Anti-Rust Pigment Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, From 2017 to 2021, my country’s anti-rust pigment market will grow at an average annual compound growth rate of about 8.2%, and the market size will reach more than 7 billion yuan in 2021. Thanks to the optimization of the industrial structure, the proportion of mid-to-high-end anti-rust pigments is increasing day by day. At the same time, driven by the increase in production costs, the average market price of anti-rust pigments continues to rise, reaching approximately 18,000 yuan/ton in 2021.

Anti-rust pigments have a wide range of applications. In recent years, with the growth of my country’s economy, the market demand for anti-rust pigments has increased steadily, growing to about 413,000 tons in 2021. my country is a major producer of anti-rust pigments. In order to meet the rising market demand, the output of the anti-rust pigment industry is also on a growth trend, reaching approximately 440,000 tons in 2021. Anti-rust pigment companies are relatively concentrated, with the total number of companies in East China and South China accounting for more than 75.6%.

There are many anti-rust pigment manufacturers, including Anhui Aobang New Materials, Lingwei Technology, Gutian Chemical, Henan Yingchuan New Materials, Wuhan Zhaoxu Chemical, etc. In the development of the market, large enterprises are gradually encroaching on the market space of small and medium-sized enterprises through corporate mergers, new factories, etc., and strengthening their competitive advantages. Some small and sophisticated enterprises are not competing with large enterprises because they focus on the research and development and market layout of special and new anti-rust pigments. Face conflicts head-on and therefore have greater momentum for development.

Industry analysts said that as one of the functional fillers, anti-rust pigments can improve the anti-rust and anti-corrosion capabilities of products and help downstream industries. In order to reduce costs and increase efficiency, in the context of high-quality development in various industries, anti-rust pigments have broad application prospects. In recent years, with the tightening of environmental protection supervision, the market demand for environmentally friendly anti-rust pigments has been growing. Against this background, new, efficient, environmentally friendly and multi-functional anti-rust pigments will gradually become the focus of various enterprises’ layout.
