The automobile spring surface USES each kind of paint layer to make the identification, is the main craft equipment which the industry produces. Good paint layer to match the car spring surface treatment, it may be said to kill two birds with one stone, with color to mark various technical parameters, the industry production, and the car spring surface anticorrosion function can be better guaranteed.

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

2, phenolic paint phenolic paint is divided into primer and topcoat two, phenolic primer adhesion, rust prevention function is good, but the paint film mechanical strength and poor luster. Due to the limitation of its own process, a large number of products have to be removed and reworked. Its disadvantage is the surface dry knot fast and stick hand time is long, easy to wrinkle, not water, not alkali.

3, epoxy paint epoxy paint adhesion is very strong, high hardness of the car spring, and good toughness, flexure resistance, impact resistance, hard but not brittle, to water, acid, alkali and a lot of organic solvents have excellent resistance, especially to alkali more convex.

4, alkyd paint alkyd paint film is tough, strong adhesion, good mechanical function, excellent luster, good durability and has a certain oil resistance, insulation function. For gas springs that match the mold, this detail is also the hinge of quality achievement. Water-soluble epoxy paints are used for electrophoretic paints. There is no strong solvent smell in the operating environment, which causes little air pollution, and the discharge process of waste water treatment is simple, as long as the PH is adjusted to settle the resin of the electrophoretic paint, and then the clean water is discharged.
