Although China's fluorine coating industry has seen notable progress over the past five years, it still lags significantly behind international competitors in terms of technology and product quality. Despite the growth, several critical challenges remain that hinder the industry's ability to reach global standards.
First, large-scale production of vinyl ether-based products is still lacking domestically. Most manufacturers rely on vinyl esters as co-monomers, which leads to irregular distribution of fluoromonomer and co-monomer units in the polymer chain. This irregularity negatively affects the weather resistance and salt spray resistance of fluorine coatings. Additionally, some fluorine resin products fail to meet standard specifications, with limited variety, monotonous appearance, and heavy color options. In certain specialized applications, suitable fluorine resins have not been developed successfully, limiting the expansion of their use.
Second, there is a lack of convincing natural exposure data, making it difficult for users to fully trust the performance of fluorine coatings. As a result, some market opportunities are lost. To address this, the Fluorine Coatings Special Committee of the China Chemical Society has initiated efforts to collect and release such data. The first batch of natural exposure results has now been made public, providing real-world evidence of the superior weather resistance of fluorine coatings. These data will also serve as a foundation for revising future industry standards.
Third, there is a shortage of professional technical personnel dedicated to fluorine coatings. No team in China has yet achieved international-level expertise across all stages—from theoretical research to industrial production, from quality control to on-site application.
Fourth, basic theoretical research in this field remains underdeveloped. Domestic researchers have published fewer monographs or detailed reports compared to their international counterparts. Moreover, scientific equipment and manufacturing facilities are also lagging. In the preparation of trifluororesin, most companies follow foreign models, often copolymerizing with chlorotrifluoroethylene and vinyl esters, which limits innovation.
Fifth, there is almost no room for room-temperature curing tetrafluororesin. Only Japan’s Daikin Corporation offers such products, and the technology behind them is strictly protected.
Lastly, the lack of fundamental research in fluorine coatings has become a major obstacle to China's goal of surpassing international leaders. After more than 20 years of effort, Japan has not only caught up with the U.S., but has also developed its own innovations. China started research on fluorine materials in the late 1950s, around the same time as Japan, but now lags far behind both Japan and the U.S. Therefore, it is essential to strengthen basic research and promote innovation to bridge this gap.
