In the current automobile manufacturing process, painting is an extremely important step, playing a crucial role in the appearance quality and durability of the car. According to different coating processes, automotive painting can be divided into the following categories.

1、 Classify by painting object

Vehicle body coating: It mainly consists of three steps: primer, topcoat, and varnish, providing a beautiful, durable, and corrosion-resistant protective layer for the car.

Component coating: The coating of automotive components such as engine hoods, doors, roofs, etc. is to meet their specific functional and durability requirements.

2、 Classified by painting method

Artificial painting: mainly through manual spraying of cars, it can mainly paint small batches, complex or special surfaces

Automatic painting: With the rapid development of industrial automation, automatic painting has entered major automobile factories. Automatic painting has higher efficiency and lower cost. Common automatic painting methods include suspension, ground rail, and robot painting.

3、 Classify according to the properties of the coating

Oil based coatings: Oil based coatings are coatings that use oil-based solvents as diluents. Despite its slow drying speed, it has excellent adhesion and covering power. Oil based coatings still have certain applications in automobile manufacturing.

Waterborne coatings: Waterborne coatings are coatings that use water as a diluent and have the advantages of low VOC emissions, non toxicity, and non flammability. Waterborne coatings have become the main choice for automotive painting because they are more environmentally friendly and safe.

Powder coating: Powder coating is a new type of coating that forms a coating by directly spraying coating powder onto the surface of a workpiece and then melting or solidifying it. Powder coatings have high decorative properties, excellent weather resistance, and corrosion resistance, but the spraying process is relatively complex.

4、 Classified by coating structure

Single coating coating: Single coating coating refers to the process of coating with only one layer of paint. Common single coat coatings include primer, topcoat, and clear coat.

Multi coating coating: Multi coating coating refers to the process of using multiple layers of paint for coating. The purpose of multi coating coating is to improve the performance of the coating, such as adhesion, durability, and aesthetics. Common multi coating coatings include primer+topcoat, primer+intermediate coat+topcoat, and other structures.
