The surface of the car seat spring adopts various paint layers for identification, which is the main process equipment produced by the industry. A good paint layer to match the surface treatment of automobile springs can be described as two birds with one stone. The use of color to identify various technical parameters facilitates the production and operation of the automobile interior spring industry, and the anti-corrosion function of the automobile spring surface can be better guaranteed.

1. Asphalt paint Asphalt paint automotive springs have good water resistance, moisture resistance, and corrosion resistance, especially excellent acid resistance and good alkali resistance.

2. Phenolic paint Phenolic paint is divided into two types: primer and top coat. Phenolic primer has strong adhesion and good anti-rust performance, but the mechanical strength and gloss of the paint film are poor. The limitations of its own process caused a large number of products to be stripped and reworked. The disadvantage is that the surface dries quickly and sticks for a long time, easy to wrinkle, intolerant to water and alkali.

3. Epoxy paint Epoxy paint has strong adhesion, high hardness of automobile springs, good toughness, flex resistance, impact resistance, hard but not brittle, and has good resistance to water, acid, alkali and many organic solvents. Especially the alkali resistance is more convex.

 4. Alkyd paint Alkyd paint film is tough, strong adhesion, good mechanical function, good gloss, good durability and certain oil resistance and insulation function. For gas springs that match the mold, this detail is also the key to achieving quality. Water-soluble epoxy paint is used for electrophoretic painting. There is no strong solvent smell in the operating environment, less air pollution, and simple waste water treatment and discharge process, as long as the resin of the PH sedimentation electrophoretic paint is adjusted, and then the purified water is discharged.
