Nowadays, the trend has been taken to reduce the organic solvent content of auto coatings.Conventional solvent-based coatings are one of the main sources of PM2.5 during use due to solvent volatilization (VOC) and severe air pollution. The organic solvent in the automotive repair paint system is the main source of VOC emissions from automotive coating processes. If it can be water-based, it can greatly reduce the emission of organic solvents. In foreign countries, if water-based Car Paint Coating is widely used in the automotive refinishing industry, it will greatly reduce the damage of refinishing paint to the environment and construction workers. Nowadays, water-based paints have sloly entered people's field of vision. At present, some 4S shops in China have adopted water-based automotive paints.
Water-based paint is a water-based acrylic emulsion as the main film-forming material. It is characterized by fast drying and low cost. The disadvantages are that it is difficult to color, the adhesion of the paint layer is poor, and the water resistance is poor.
