PTFE and PVDF fluorine resin coatings basically rely on imported resins, require high-temperature barbecue filming, and are mainly applied in industrial coating. The application fields are relatively narrow. They have been in a stable growth period in recent years. The market and technology are basically monopolized by foreign companies, and the market capacity is The development space is relatively stable and development is slow. FEVE fluororesin coating is just the opposite, mainly based on domestic companies, foreign companies only occupy a very small market share. Because FEVE fluororesin coating can be cured at room temperature, the price has a competitive advantage, and the application field covers many industries such as construction and industry. Especially in recent years, under the active promotion of domestic enterprises led by Zhenbang, FEVE fluororesin coating has been Construction industry, especially some key projects have been widely used. In China, FEVE fluorine resin coating market with Chinese characteristics has been initially formed, which has laid a good market foundation for the rapid development of China's fluororesin coating industry.
The development of China's FEVE fluorine resin coating has experienced the market expansion period from 1999 to 2004 and is now entering the market development period. With the industrial upgrading and product upgrading of the paint industry in China, it is expected that FEVE fluorine resin coatings will achieve extraordinary development in this century, and will form a high-performance paint market dominated by fluororesin coatings for four reasons: First, a large number of domestic The rise of fluororesin coating manufacturers and specialized fluorine coating research institutions has laid a foundation for enterprises and a technological foundation for the market competition of fluorocarbon paints. In the early 90s of the last century, China's FEVE fluorine resin coating and other fluorine coatings rely on imports, the price is expensive, the market volume is very small, the annual consumption is only tens of tons. In 1997, China's first FEVE production line with an annual output of 1,000 tons with independent intellectual property rights was established in Dalian. The project was rated as a National Key Torch Program project. However, due to incomplete technology and market operation, there are certain problems, and soon after production. It is in a state of production suspension. In 1999, Dalian Zhenbang purchased the project as a whole, and invested funds for technical reorganization and market development. After six years of development, Zhenbang's fluorine coating products have entered the three major markets of construction engineering, industrial anti-corrosion, and home decoration, and formed The 8 series products, invested 200 million yuan in 2004 to build Asia's largest FEVE fluorine resin and fluorine coating industrialization base. In addition, FEVE fluororesin production facilities such as Zhongshu in Changshu, Kangtai in Zhejiang, and Hongfeng in Qingdao have also been successively put into production. China's FEVE fluororesin has been expanded by 20 times in just a short period of 5 years, with a production capacity close to 20,000 tons. And more than 100 large and small professional and non-professional fluorine coating manufacturers have also emerged, further establishing the industrial base of China's FEVE fluorine coating. Dalian Zhenbang Research Institute of Fluorine Materials and Wuhan University and other research institutions in recent years on the FEVE research has continued to emerge, in particular, Dalian Zhenbang with independent intellectual property rights of the 4,000 tons of water FEVE fluorine resin production line successfully put into operation, and passed The joint appraisal organized by the Chinese Academy of Sciences and the Ministry of Construction has made a positive contribution to the sustainable development of the environmentally friendly FEVE industry.
Second, the approval of the national industry authorities and the pending approval of the national fluoroplastic coating industry standards laid the foundation for the development of fluorocarbon paints and a good market development environment. In 2002, the Ministry of Construction will include a silicon-acrylic-coating fluororesin coating as the top-grade coating for China's external walls. It is recommended to be widely used in high-rise buildings. In 2004, the National Standardization Technical Committee of Paints and Pigments officially submitted cross-linked fluororesin coatings as an industry standard. The formulation and implementation of this standard has positively promoted the market of FEVE fluororesin coatings and promoted its healthy and orderly development.
Thirdly, a large number of domestic projects and industries have successively applied fluorocarbon paints, including a large number of influential buildings such as the National Sports Center, which began to designate fluorocarbon paints and laid a good market foundation. As of 2004, China's FEVE fluorocarbon coating area totaled approximately 20 million flat meters, and in 2005 it is expected to exceed 5 million square meters. The application area is mainly based on the external walls of buildings and supplemented by corrosion of steel structures. With the completion of a number of influential projects in the country, the replacement of aluminum curtain walls with metal fluorocarbon paints and the use of waterborne fluorocarbon paints to replace acrylic exterior wall coatings have become hot spots in the market. The market share of fluorocarbon paints in the external walls has been rising rapidly. At the same time, some of the country’s major anti-corrosion and industrial equipment for steel structures such as bridges and pipelines have begun to use fluorocarbon paints in large quantities, so that the excellence of fluorocarbon paints will continue to gain recognition in market applications and the market will enter a period of rapid development.
Fourthly, the price of charcoal paints for books and newspapers has been diversified, and the diversification of market applications and the improvement of the application of supporting technologies have enabled fluorocarbon paints to replace other paint types, realizing the upgrading of the paint industry, and greatly expanding the market for fluorocarbon paints. The development of space. For a long time, both domestic and foreign, fluorocarbon paints have been aristocratic products. The prices are extremely high and the fields of use are narrow. Before 1999, the price was as high as 340,000 yuan/ton. Japan's FEVE resin is only tens of tons per year in China. Fluorocarbon paint is generally only one of the few professionals in the industry understand that the general public have little understanding of fluorocarbon paint. In 1999, after Zhenbang began to enter the fluorocarbon paint market, adopting the strategy of popularization of prices and diversification of the market, China's FEVE fluorocarbon paint market has achieved rapid development, and the price of foreign products has been reduced by nearly 50%. The price of fluorocarbon paint is slightly higher than that of imported high-grade acrylic polyfluoroester coatings, which has led to the use of fluorocarbon paints in many fields, including railways, passenger cars, ships, and bridges, to replace the acrylic urethane coatings that currently dominate the mainstream of high-end coatings. The fluorocarbon paint market space.
China's fluorine coating products mainly have three series. One is PTFE-based high-temperature baking type PTFE coating, mainly used for high temperature resistant kitchen utensils, the main product is the United States DuPont's TEFOLN, with production in Shenzhen factory. In addition, Japan Daikin also has a production plant in Changzhou, with an annual output of about 1,500 tons. This market is relatively stable, mainly foreign manufacturers. The second is PVDF-based hot-melt type fluororesin coating, mainly used for aluminum and aluminum plate surface fluorocarbon spraying, the main products to KYNAR500 or HYLAR5000 fluorocarbon resin, the main manufacturers mainly AkzoNobel and PPG companies, Shanghai and Tianjin have cooperation and production bases, and the annual consumption is about 2,000 tons. The third is FEVE-based normal-temperature curing cross-linked fluororesin coating, the resin manufacturers are Dalian Zhen, Changshu Zhongyu, Changzhou Kangtai, Qingdao Hongfeng, etc., of which Dalian Zhenbang is China's largest FEVE fluorine resin and fluorine coating leading enterprises. .
