Covestro joins hands with Sany Heavy Machinery to realize large-scale water-based coatings in China’s construction machinery industry

With the support of partners such as German material manufacturer Covestro, Sany Heavy Machinery, a Chinese excavator manufacturer, became the first large-scale water-based coating in the Chinese construction machinery industry. strong>Green painting company.
In recent years, the construction machinery industry has achieved rapid development in Greater China, and environmental protection requirements have become increasingly stringent. In this context, construction machinery manufacturers are paying more and more attention to water-based coating, and their requirements for product performance and construction technology are getting higher and higher.
China not only needs GDP, it also needs green mountains and clear waters, and enterprises must assume social responsibilities. Yu Hongfu, chairman of Sany Heavy Machinery Co., Ltd., said that Sany’s goal is to occupy an important position in the global market. In the process of achieving global layout, we must not only consider China’s environmental protection requirements, but also consider developed countries in the longer term. Requirements for paint.
Based on these considerations, SANY Heavy Machinery began to evaluate and test various low-VOC (volatile organic compound) coatings in 2014, and finally the comprehensive indicators of water-based coatings came to the fore. At present, its Kunshan Park has deployed 10 water-based coating production lines, which fully meet the performance requirements of solvent-based coating, and will be further promoted in other factories of Sany Heavy Machinery in the future.
Using water-based paint instead of solvent-based paint can reduce VOC emissions by more than 80%. Taking into account the complexity of water-based coatings, we mainly choose excellent coating suppliers and material suppliers at home and abroad for cooperation and support. Said Qi Xiangan, director of Sany Heavy Machinery Coating Research Institute.
As a long-term partner of Sany Heavy Machinery, the world’s coating factory Shang Sherwin Co., Ltd. assisted Kunshan Sany to deploy a water-based coating line in November 2017, achieving large-scale production and successfully Apply water-based coatings to the construction machinery industry.
Construction machinery and equipment are mainly operated in the open air, so there are high requirements for anti-corrosion performance, appearance, and gloss. Sherwin-Williams is committed to developing new water-based and low-VOC coating products to meet various mechanical coating performance indicators. We work with upstream raw material suppliers to provide customers with solutions on coating performance, construction technology, and how to transform water-based coating construction applications at low cost. Sherwin-Williams General Manager of Industrial Coatings Asia, said Wu Zhonghua.
In China, many construction machinery manufacturing workshops still need to rely on manual spraying due to the inability to control temperature and humidity. This is a big challenge for water-based paint construction. In response to this feature, Sherwin-Williams Coatings and Covestro have developed an easy-to-spray water-based two-component polyurethane coating technology that is specially developed by local research and development. Through more environmentally friendly high-performance water-based coatings, China’s construction machinery coatings industry can achieve technological upgrades, which can be more satisfying. Increasingly stringent regulatory requirements.
Covestro’s two-component waterborne polyurethane coating technology for the construction machinery industry can not only meet or exceed traditional solvent-based coatings in terms of performance, but also has a spacious construction window and is easy to spray, and its VOC content can also meet the latest Chinese regulations and standards.
Li Jinqi, vice president of technology application development of Covestro’s Covestro Coatings, Adhesives and Specialty Chemicals business unit, said: In recent years, Covestro’s water-based coating technology has been successfully applied to more and more downstream industries and has become a leader in water-based coatings. Indicators, one of the keys to success factors is industrial chain cooperation. We not only cooperate with downstream customers, but also with end customers. For example, with client Sherwin-Williams and end-user Sany Heavy Machinery, we discussed how to apply water-based coating technology solutions in the field of construction machinery. We are committed to promoting the development of green coatings, and we have the same goal on this point.
