To curb air pollution in China's capital, the Beijing Municipal Bureau of Environmental Protection has adopted a policy paper that provides for the two-stage reduction of emission levels for maintaining and repairing wind turbines and other structures. In line with this regulation, the threshold values valid up to the end of 2016 will be tightened again starting in 2017.
The threshold limit values for industrial coatings expected to come into effect by 2022 in Beijing/China are already satisfied by the wind energy-industry portfolio offered by BASF's Coatings division. Coating solutions for wind turbines developed and sold under the Relest brand feature high abrasion resistance and elasticity and thus offer long-lasting protection from extreme weathering impacts. For this purpose, BASF has developed a special coating system consisting of gelcoat, putty, edge protection and topcoat. The used two-component polyurethane compounds offer an ecological alternative to solventborne products.
