The development trend of anti-corrosion coating technology and market in China

Anti-corrosion coatings are a type of coating that is widely used in modern industries, transportation, energy, Marine engineering and other sectors. According to the corrosion resistance of its coating film layer and the application requirements, it is usually divided into two types: conventional type and heavy-duty anti-corrosion type. Anti-corrosion coatings are playing an increasingly important role in the coating industry. The development of anti-corrosion coatings is of great significance to the economic development of our country. It is estimated that the total output of anti-corrosion coatings will reach about 6 million tons by 2017. Due to the wide application range and extremely important position of heavy-duty anti-corrosion coatings in the industry, as well as their significant role in energy conservation and emission reduction, the state encourages and supports the research and development and production of heavy-duty anti-corrosion coatings. It is expected that in the future, some of the production capacity of conventional anti-corrosion coatings will shift to heavy-duty anti-corrosion coatings.

Anti-corrosion coatings in China are mainly applied in the chemical and petroleum industries, railways, highway Bridges, metallurgical industries, power and energy industries, machinery and textile industries, industrial product fields, automobiles, ships and container industries. Among them, the industries with the greatest demand are the chemical and petroleum industries, which include anti-corrosion of steel structures and reinforced concrete structures in oilfield facilities, oil pipelines, offshore platforms, and petrochemical plants. Meanwhile, the construction and maintenance of railway and highway Bridges are also key areas for the application of anti-corrosion coatings. In addition, the industrial products sector as well as Marine anti-corrosion fields such as automobiles and ships are also the largest demand points in the anti-corrosion coatings market. While anti-corrosion coatings in our country are constantly developing, they are also advancing in the direction of high performance, high efficiency, low energy consumption and low pollution. Ship anti-corrosion, oil platform anti-corrosion, container anti-corrosion, anti-corrosion coatings for chemical industry, railway and highway Bridges, and anti-corrosion of steel structures remain the market focus. Meanwhile, the scale of competition in anti-corrosion coatings is bound to expand, the competitive situation will become more and more obvious, and international cooperation will become increasingly important.

Data shows that the average annual growth rate of the output of anti-corrosion coatings for the petrochemical industry, the power industry and building steel structures will remain at around 20% in the next five years. The average annual growth rate of the output of anti-corrosion coatings for ships and railways will remain at around 17%. The average annual growth rate of the output of anti-corrosion coatings for Bridges, docks and containers will remain at around 8%.

The future development directions of anti-corrosion coating products mainly manifest in the following aspects:

Develop water-based anti-corrosion primers and topcoats for steel structures;

2. Develop a series of high-solid content and solvent-free anti-corrosion coatings;

3. Develop water-based zinc-rich primers;

4. Develop heat-resistant and anti-corrosion coatings for heat exchangers that can be cured at room temperature;

5. Develop coatings that can cure at room temperature and are convenient to apply;

6. Develop substitutes for chlorinated rubber series anti-corrosion coatings;

7. Develop flaky anti-corrosion coatings;

8. Develop organic-modified inorganic anti-corrosion materials.

Meanwhile, the future trends of the anti-corrosion coatings market and enterprises:

Water-based anti-corrosion coating products are favored.

2. Coating technology and painting technology are more closely integrated.

3. Attach importance to clean production.

4. The market and products are more refined.

5. Attach importance to the research on production process technology.

With the development of China's infrastructure construction, industrial structure adjustment and emerging industries, anti-corrosion coatings have undoubtedly become an important field and branch in the coatings industry and market system. The related participating enterprises, technological development, product systems, market size, actual demand, application fields and role play have all reached new levels at present. Moreover, many industry experts believe that Among industrial coatings, anti-corrosion coatings have the most advanced manufacturing scale, high production efficiency and good capacity utilization. Anti-corrosion coatings have become an important force in the coating field, playing an increasingly significant role and having a promising development prospect.
