Fluorine powder coating is one of the development directions of high-end coatings in China

According to relevant data and data, China’s annual loss due to corrosion of steel structures amounts to more than 100 billion yuan. If it can completely use fluorine coatings, which have excellent performance for anti-corrosion coating, it will not only save a lot of money, but also bring about significant economic benefits. At the same time, it can reduce the related loss and disaster caused by corrosion, and it also has great social benefits.

Fluorocoatings are widely used. For example, it can be used in anti-corrosion and protective coating projects such as cross-sea bridges and general marine engineering, storage tanks and pipelines of chemical plants, highway guardrails, power engineering, general steel structures and external walls of buildings. Due to its long-term weather resistance, corrosion resistance, and good self-cleaning and decorative properties, the fluorine coating has a service life of 15 to 20 years, which is 3 to 5 times the service life of common coatings.

From the history of the development of fluorine coatings: 1938, the United States DuPont company first developed a fluorine coating. In 1982, Asahi Glass Co., Ltd. of Japan developed a second-generation fluorine coating. This kind of fluorine coating in Japan can be coated by conventional methods such as brush coating, roll coating, and spray coating like ordinary coating materials, thus greatly expanding the application of fluorine coatings. field. However, at that time, the technology of this product was only in the hands of the Japanese, and the technology was strictly controlled, causing the price of the fluorine coating product to be expensive.

The development of fluorine coatings in China started relatively late, but from the current point of view, fluorine powder coatings is one of the development direction of China's high-end coatings. It is more environmentally friendly than solvent-based fluorine coatings and meets the national low-carbon and environmental-friendly industrial policies. At present, only three companies, Ocica powder coating company, Japan Daikin Corporation, and Japan Asahi Glass Co., Ltd. can produce, and the price is relatively high. Fluororesin is the core raw material for producing fluorine coatings. Fluororesin, because of its special atomic structure and molecular composition, is generally more stable than other organic compounds, extremely resistant to chemicals, and insoluble in any solvent. The successful development of fluorine powder resin and coating will enhance the competitiveness of the national paint industry in the powder coating high-end market and improve China's position in the international fluorine chemical industry. At present, fluorine powder coating products developed in China still have a gap in performance with similar foreign products, and further improvement is needed.
