With the rapid development of the automotive industry, the usage of automotive coating is also constantly increasing. Automotive coating mainly include primer, intermediate coat, and topcoat, among which the topcoat is further divided into natural color paint and metallic flash paint. The water-based process of automotive coating is gradually carried out from bottom to surface. At present, more than 90% of the primer has been water-based coating, and 88% of the automotive intermediate coating have also adopted water-based technology. The application of water-based metal flash primer has exceeded 65%.

The successful application of water-based coating in the automotive industry mainly benefits from the following aspects:

First, water-based coating is low-carbon and environmentally friendly.Compared to traditional oil-based car coating, the emission of harmful substances VOC in water-based coating is reduced by 70% compared to oil-based coatings. This is beneficial for protecting the environment and conforms to the trend of low-carbon environmental protection.

Second，water-based coating itself has excellent performance. In terms of vehicle painting, water-based paint has better leveling, adhesion and wear resistance, which makes the topcoat more vivid and full, and is resistant to stone impact and scratches.Using water-based paint for touch-up paint has a similar color and luster. The functions are closer to the quality of the original factory, and more in line with the consumption needs of car owners.

Third，the application of water-based coating helps to reflect the social responsibility of automobile companies and enhance their corporate image.Water-based automotive coating has good performance and is low-carbon and environmentally friendly. They can not only improve the service quality and image of automobile companies, but also have positive significance for environmental protection and help shape the image of companies assuming social responsibility.

Fourth,the application of water-based coating provides a safer and healthier environment for auto painting workers. Water-based coating contains a lower proportion of harmful substances, which helps to protect the health of paint workers.
