Fluorocarbon coating: The trump card among outdoor anti-corrosion coatings

Fluorocarbon coating: The trump card among outdoor anti-corrosion coatings. Outdoor steel structures, curtain walls, and offshore facilities are exposed to the sun, rain, and salt spray all year round. Ordinary coatings will fade, peel, and rust in just a few years. Frequent renovation and maintenance costs remain high. FEVE solvent-based fluorine-containing polyurethane coating can achieve ultra-long weather resistance and anti-corrosion. 1. What is FEVE fluorocarbon coating? FEVE, the full name of fluoroolefin-vinyl ether copolymer, is the core film-forming resin of fluorocarbon polyurethane coatings. The raw material is synthesized by alternating copolymerization of fluoroolefin and vinyl ether monomers, which is essentially different from traditional fluororesins such as PTFE and PVDF. The fluorine segments in the molecule can build a dense protective film to resist ultraviolet rays, acid and alkali, and salt spray corrosion. ； The hydroxyl reactive group of vinyl ether can be used with isocyanate curing agent to cure at room temperature without high-temperature baking. It can be directly constructed on a large area on site. It also takes into account the super weather resistance of fluorine materials and the flexibility and easy construction of polyurethane paint films. 2. Performance advantages: The biggest highlight of ultra-long aging resistance FEVE is its extremely slow aging speed, and its long-term protection capability has been verified by long-term actual testing. A 15-year outdoor natural exposure comparative experiment in the Japanese industry shows that under the same environment, ordinary acrylic polyurethane topcoats are prone to powdering, loss of gloss, and discoloration. FEVE coatings have no blistering or large-area powdering after long-term use, and have outstanding gloss and color retention. In laboratory xenon lamp and QUV accelerated aging tests, the appearance of the paint film showed no significant degradation after thousands of hours of exposure. Compared with conventional anti-corrosion paints, FEVE’s initial purchase price is high, but its service life is greatly extended. In the later period, there is almost no need for frequent repairs and re-coatings. The overall life-cycle cost is lower. It is a cost-effective solution for one-time coating and long-term protection. It is a necessary long-lasting anti-corrosion coating for cross-sea bridges, offshore platforms, and high-end curtain walls. 3. Domestic and foreign industrial structure FEVE resin synthesis process is complex, supporting environmental protection processing requirements are high, technology and production capacity barriers are high, and the global effective production capacity is concentrated in a few leading manufacturers. The overseas high-end market is led by Japan's AGC Asahi Glass and Daikin Industries, which early monopolized the supply of high-end fluororesin. ； After years of domestic technological breakthroughs, companies such as Dalian Zhenbang, Changshu Sanaifu, and Shandong Dongyue Polymer have achieved large-scale mass production of resins and finished coatings. Domestic products continue to seize the mid-to-high-end market, and the process of domestic substitution is accelerating. Today, my country is the core production base of FEVE resins and coatings in the world. 4. Downstream applications 1. Industrial heavy-duty anti-corrosion: Cross-sea bridges, offshore wind power platforms, and port equipment can withstand high salt spray and humid marine environments. ； 2. High-end building curtain walls: Facades of commercial buildings and landmark buildings can maintain their appearance for a long time and reduce the frequency of maintenance. ； 3. New energy and large-scale infrastructure: Wind power towers, large steel structure factories and other outdoor long-term service facilities. The global FEVE coatings market size will be approximately US$429 million in 2025. Asia-Pacific is the core consumption area. Domestic infrastructure upgrades and marine economic development continue to drive demand, and the market size is growing steadily. 5. Future development direction of the industry 1. Process optimization: Improve copolymerization technology, improve fluorine utilization efficiency, reduce raw material costs, and accelerate domestic substitution ； 2. Environmental protection upgrade: While retaining the advantages of solvent-based FEVE construction and weather resistance, we develop low-VOC modified products to adapt to increasingly stringent environmental regulations. ； 3. Increased market penetration: The demand for long-life coatings in infrastructure, marine engineering, and high-end buildings continues to increase, and the application scope of FEVE long-lasting protective coatings continues to expand. Domestic domestic companies have achieved large-scale mass production and continue to break overseas technology monopolies. With the expansion of downstream infrastructure and marine industries and the iteration of resin processes, the market space of FEVE fluorocarbon coatings in the field of long-term protection will continue to expand.
