Weng Hanyuan: the development of polyurethane coatings is locked in four directions


Deputy Secretary General of China Polyurethane Industry Association Weng Hanyuan: the development of polyurethane coatings is locked in four directions

after the 1980s, China's Polyurethane Coatings entered a period of rapid development and formed two production bases in the Pearl River Delta and the Yangtze River Delta. Polyurethane coatings have been widely used in wood furniture, heavy metal corrosion protection, coiled materials, plastics, automobile finish, aircraft skin paint and other fields, especially in wood furniture paint. However, since more than 90% of polyurethane coatings in China are solvent based products, there is a great pressure on environmental protection, so the research and development of non solvent products is very urgent

according to the data, at present, polyurethane coatings account for 75% of wood furniture coatings in China. China's woodworkers are not able to print their graphics. The current consumption of paint is about 400000 tons, that is, 300000 tons of polyurethane wood paint will be consumed. However, it broke down after 20 years. In 2004, the total domestic output was only about 200000 tons, and there is still much room for development. (2) Starting from the sustainable development strategy, the Chinese government is strengthening the energy conservation, safety, environmental protection regulations and standards of the polyurethane industry to be in line with international standards, and guiding the industrial development and R & D direction. At present, the most important thing is to reduce or eliminate the application of organic solvents. The preparation of water lotion or water dispersible coatings with water instead of organic solvents is a hot topic in the world. The standards are well structured and reasonable, and China is no exception. There are dozens of scientific research institutes, colleges and universities and production enterprises in China. At present, some products have been formed and applied

the development of polyurethane coatings should focus on four directions. First, the enterprise is developing towards specialization, collectivization and scale; Second, the products are developing towards high-tech content, high quality and multi-function; Third, the market radiates and expands outward, and the market positioning of products is developing towards globalization; Fourth, the varieties are developing towards environmental protection. Low pollution, low energy consumption, hydration, high solid content and powdering are the development trends of polyurethane coatings in the future
