Environmentally friendly functional coatings for cars and high-speed rail

At the China Traffic Development and Green Coatings High-Level Forum held in Shanghai last week, a consensus was reached on nearly a hundred domestic paint industry chain representatives on how China's paint industry’s technological innovations capture the “Twelfth Five-Year Plan†strategic opportunity: China’s autos, high-speed rail and other transportation The paint business is tempting, and the paint industry can regard this as a new growth point for the “Twelfth Five-Year Plan†start. R&D and promotion of environmentally-friendly and functional products will drive China from a paint major country to a paint powerhouse.
Gu Xianghua, an expert from the China Association of Automobile Manufacturers, predicts that China’s auto industry will continue to grow steadily during the “12th Five-Year Plan†period, becoming the engine of China’s economic growth, which will bring huge business opportunities to the paint coating industry. According to the introduction of the person in charge of Bayer MaterialScience's Coatings Business Unit, the VOC problem is currently prevalent in vehicles. In order to limit VOCs, solutions for high solids coatings, powder coatings, and waterborne coatings have generally been adopted internationally, and only the waterborne coatings among the three are truly green. Bayer has developed waterborne raw materials and proven technological solutions for this purpose.
Zhou Jie of SAIC Group Volkswagen believes that it is necessary to expand the scope of water-based paint to solve the temperature and humidity control technology, shorten flash-drying time of water-based paint and the pre-heating time of mid-coating, and develop low-temperature curing technology. PPG's experience has proven that through the enhancement of technical services and training, the number of users of its water-based refinish paint has increased by spurt in 2010, a 130% increase over the previous year.
Qian Borong, chief engineer of CNOOC's Changzhou Coatings Chemical Research Institute, told reporters that waterborne coatings in China are still in their infancy. They are mainly subject to higher raw material prices and the need for transformation of the original coating equipment. He pointed out that at present China has already proposed that the new large-scale automobile painting line must use water-based paint, which is encouraging. He believes that during the 12th Five-Year Plan period, there will be great development in the use of water-based coatings for vehicles in China, including the use of waterborne coatings for rail vehicles.
China has entered the era of highways and high-speed railways, bringing huge markets for special coatings for roadbeds, piers, beams and bridges. Taking the Beijing-Shanghai high-speed railway with a total investment of 220 billion yuan as an example, its full-line coating area is approximately 1200 square meters, and all domestic polyurea coatings are used. Professor Huang Microwave of Qingdao Institute of Technology introduced that because the polyurea coating is dense and seamless, the protection performance is very good, and unique technical specifications are created in the construction. It has been successfully applied in the Beijing-Shanghai high-speed rail protection project, completely changing the The backwardness of China's material protection field.
Zhao Xiaodong, chairman of the China Chemical Society’s Fluorine Coatings Professional Committee, told reporters that during the “Twelfth Five-Year Plan†period, the development of high-performance coatings such as high corrosion resistance, high temperature and low temperature resistance, high sand resistance, salt spray, and fire retardant coatings is the direction of innovation. The repainting cycle was extended from the regular 5 years to 5 to 10 years.
