The next 10 years will be a period of great changes in automotive painting technology all over the world. The role of painting pipeline, painting process, materials, equipment and management in improving automotive performance, reducing investment, saving energy and reducing consumption, and protecting the environment, is increasingly recognized by coating industry technicians. Famous paint material suppliers and equipment suppliers all over the world have developed energy-saving integrated processes and new equipment, simplified existing processes, reduced investment and operating costs, reduced VOC and CO2 emissions, and met the requirements of resource saving and clean production.

1 New Coating Technology

The role of paint materials in improving automotive performance, reducing investment, saving energy and reducing consumption and protecting the environment is increasingly recognized by technical personnel in the painting industry. Most famous paint suppliers have developed compact energy-saving and environmental protection processes based on paint materials to reduce investment in painting equipment and production and operation costs. Reduce VOC and CO2 emissions, achieve the purpose of resource saving and cleaner production.

1.1 Wet Touching Process of PVC Sealant

The wet rubbing process of PVC sealant refers to the process that the PVC sealant does not need pre-baking after construction, sprays paint directly on its wet film surface, and then conductor automatic vulcanization line is heated together with the paint drying room for gelatinization. This kind of automotive PVC undercoat and sealant is constructed without pre-baking because of the PVC sealant. The glue surface and middle paint are both liquid, so it is called "wet touch wet" process.

The process saves the investment and area of PVC drying equipment, simplifies the painting production process, reduces the energy consumption of pre-drying of PVC sealant in painting production, and achieves the goal of reducing the production cost of automobile painting. However, due to the phenomenon of loss of light, discoloration, foaming and so on, it is necessary to pay attention to the compatibility between PVC sealant and middle paint. At present, the wet-wetting process of PVC has been applied in domestic painting workshop, and the material and technology are relatively mature.
