Heavy-duty anticorrosive coatings have a high technical content

The heavy-duty anticorrosive coatings are widely used in modern industry, transportation, energy, marine engineering and other departments. According to the corrosion resistance and application requirements of its coatings, it is usually divided into two types: conventional type and heavy-duty type. Anti-corrosive coatings play an increasingly important role in the paint industry. The development of anti-corrosive coatings is of great significance to China's economic development.

Heavy-duty anticorrosive coatings have become a relatively high concentration area of the coatings industry market, especially the high-end market is almost monopolized by large international companies because of its high technology content and high entry threshold. Akzo Nobel of the Netherlands, Jotun of Norway, Chugoku of Japan, PPG of the United States and Hempel of Denmark adopt the strategy of global operation, and their global market share is more than 50%. The top ten companies in the world have a global market share of 67%.

Coatings are important functional materials in the national economy. They can be coated on the surface of objects by different construction techniques to form solid films (coatings) with strong adhesion, strength and continuity, thus protecting, decorating and enhancing the value of products. Made-in-China 2025 will comprehensively promote the implementation of manufacturing power strategy and realize the transformation from Made-in-China to "Made-in-China Intelligent Manufacturing". Coatings industry is the first to achieve the transformation of the industry. Coatings industry is facing more challenges.

China's paint consumption market is huge, but most of the paint market share is occupied by international paint giants, and the share of local coatings is low, especially marine anticorrosive coatings. With the continuous development and upgrading of technology and the introduction of policy dividends by domestic enterprises, the industrialization process of graphene anticorrosive coatings in China has accelerated, and the localization of graphene coatings has moved from blueprint to reality, breaking the monopoly of foreign enterprises in this field. The application of graphene in coatings has strong hardness and corrosion resistance, and the price of the same quality anticorrosion is about 20% lower than that of imported coatings, which provides an alternative for the large market in the field of heavy-duty anticorrosion. At present, many enterprises have also seen the market, and have begun the research and development and production of graphene heavy-duty anticorrosive coatings. With the promulgation of Made in China 2025, the prosperity of equipment manufacturing industry has injected power source into the development of anticorrosive coatings, and the market development of graphene heavy anticorrosive coatings will be more rapid. In order to adapt to the development of the times and the requirements of environmental protection, environmental protection will be the main direction of heavy-duty anticorrosive coatings in the future. Because of the advantages of waterborne coatings, it has been rapidly applied in the field of heavy corrosion protection. Waterborne heavy-duty anticorrosive coatings have good anticorrosive properties and are widely used in bridges, containers, petrochemical industry, tanks, pipelines, wind power generation and industrial buildings. With the wide application, the development of high-performance waterborne heavy-duty anticorrosive coatings is more and more frequent, and the product types are more and more. In the future, waterborne heavy-duty anticorrosive coatings will have good development prospects both in quantity and variety.
