1. Water based resin coatings save resources and low pollution. Water is used to replace organic solvent in water-based coatings. The water source of waterborne resin coating is extensive, which can save a lot of resources. In the process of production, transportation and painting, there are basically no pollutants and fire risk, so it is beneficial to protect the ecological environment.
2. Water based resin coating the surface of the object to be coated can be coated without completely drying after degreasing, derusting and phosphating treatment. When electrodeposition is used for waterborne resin coatings, there are more stringent requirements on the surface treatment of the coated objects. Construction equipment and tools can be cleaned with water.
3. The automatic electrodeposition construction method is adopted for the electrophoretic coating of waterborne resin coating, the coating efficiency is higher than that of spray, brush, shower, immersion and other construction methods, and the coating quality is stable with less disadvantages; Other waterborne coatings can be sprayed, brushed and dipped.
4. There are a lot of hydrophilic groups in waterborne resin coatings, so the corrosion resistance of coatings should be improved. Water based coatings for water-based coatings dried at room temperature, effective measures should be taken to ensure that the water in the film is released within the specified time. This is a subject worthy of attention in the process of formulation design, production and coating of waterborne coatings.
