Problems in the development of waterborne resin industry
Date:
2020-04-15
In the domestic application field, the high cost is the main factor restricting the wide application of water-based resin (water-based resin project feasibility study report), and some performance is still lower than solvent-based polyurethane is also an important reason. Compared with solvent-based polyurethane, water-based resin still has problems such as long drying time, weather resistance, water resistance, heat resistance, poor initial adhesion 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, and the application is mainly based on small and medium-sized enterprises in coastal areas using foreign technology. Domestic enterprises in the finished product testing means, production control means compared with international manufacturers.

There is still a big gap between domestic enterprises and international manufacturers in terms of finished product testing methods and production control methods. At present, some enterprises in the introduction of foreign production equipment, the implementation of fully automated control, improve the precision level of the production process, stable product performance indicators. Wan Xia water-based resin in adhesion, weather resistance have reached a new industry height, the future will continue to develop to meet the market demand of water-based industrial anticorrosive paint resin.
