COSCO Kansai Coatings introduced the first wind turbine tower coating, a fluorocarbon coating, which has significantly improved the performance of existing polyurethane coatings. It can significantly increase the service life of the tower and provide up to 20 years of long-term protection.
COSCO Kansai Paint & Chemical Co., Ltd. ("COSCO Kansai"), as the leading company in industrial anti-corrosion coatings, introduced the first fluorocarbon coating for wind turbine towers, which can effectively improve the reliability of wind turbine towers and extend their service life. Up to 20 years of long protection.
The current wind power coatings are based on European and American standards for polyurethane coatings, mainly because at the beginning of the development of the wind power industry, the development of long-term weather-resistant top coats in Europe is not yet mature. Therefore, the most technologically advanced and relatively weather-resistant paints have been selected. Polyurethane coating as protection. In general, polyurethane coatings are limited in life. In order to ensure the fan's 20-year service life, repainting and maintenance are required for many times, which greatly increases equipment maintenance costs and safety risks. On-site repainting of wind power equipment is extremely difficult. The cost of transportation and downtime maintenance is much higher than the cost of the initial coating itself. Therefore, there is an urgent need for a high-performance long-term protective coating that is compatible with it, and the full-life design of the anti-corrosion coating of the fan equipment becomes a crucial factor.
Fluorocarbon coatings are known as the "king of paints" due to their superior weathering resistance and stain resistance, and are the coatings with the lowest amount of aging film loss in outdoor years. In theory, a 20-micron film thickness can meet the requirements of 40 years of corrosion protection. Claim. The fluorocarbon paint for wind turbine towers developed by COSCO Kansai Co., Ltd. has less than 1â„4 of the annual loss of paint films of similar polyurethane products. During the normal service life of fans, no maintenance or only one maintenance is required. Guarantee 20 years of anti-corrosion period, and can significantly reduce the overall cost of painting by reducing the number of maintenance. Because the film thickness of its design is lower than the film thickness of traditional polyurethane coatings, VOC gas emissions can be reduced in the coating process, which in turn saves social resources and energy, and reduces environmental pollution to a greater extent.
The product is composed of tetrafluororesin, aliphatic polyisocyanate and high weather-resisting pigments, etc. It has super weathering resistance, powder resistance, excellent gloss and color retention, and tough film. It has excellent mechanical wear resistance. The mechanism of action is to form a reliable coating protective layer with the fluorocarbon topcoat and other supporting coatings, and to fully utilize the super weather resistance, corrosion resistance, and excellent physical and mechanical properties of the fluorocarbon coating to provide shielding of the substrate. Role, to extend the effective life of the coating protective layer.
At present, the ultra-high performance of fluorocarbon coatings has been fully recognized by the industrial anti-corrosion market. If wind power anti-corrosion market is introduced in the future, the performance of wind power equipment such as weathering and anti-corrosion can be greatly improved, the period of equipment protection can be extended, and the maintenance cost can be reduced. Compared to the polyurethane system coatings used in current wind power facilities, fluorocarbon system coatings will become upgraded products. It will play a very positive role in promoting the upgrading of wind power coatings in China.
