Development of China's waterborne resin industry
The production enterprises of waterborne resin are mostly concentrated in East China and South China, while Zhejiang, Jiangsu, Shandong, Shanghai and other places are the main ones in East China; Guangdong Province is the main distribution Province in South China. Generally speaking, there are not many enterprises in the production of waterborne resin, and the process needs to be improved.

Discussion on the production process of chromium free pretreatment spraying
The average price of solvent based paint is 150-250 yuan / L, and the average price of water-based paint is 300-400 yuan / L, so the price of water-based paint is about 1 times higher than that of solvent based paint, about 150 yuan / L higher.

Problems in the development of Waterborne Resin Industry
In the field of domestic application, high cost is the main factor restricting the wide application of waterborne resin (feasibility study report of waterborne resin project), and some properties are still lower than solvent polyurethane is also an important reason. Compared with solvent polyurethane, water-based resin still has some problems, such as long drying time, weather resistance, water resistance, heat resistance, poor initial viscosity and stability, and relatively poor adhesion to low surface energy materials. At present, the development of water-based resin in China is still very unbalanced. The main application is that small and medium-sized enterprises in coastal areas adopt foreign technology processing.
