Process of underbody coating
1.Pre Treatment
- The first sequence in preparing the BIW for subsequent coating is pretreatment.
- Pretreatment helps the primer bond to the metal.
- The solution comprises alkaline salts and surfactants and can include caustic soda, trisodium phosphate, and sodium carbonate.
2.Electrodeposition (ED):
It is a method of painting, which uses electrical current to deposit the paint. This process is also known as electro-deposition. The sides of the tank, which is connected to the rectifier's positive potential
- Rust-Proof materials:
- In this method seam sealing uses Pic (Polyvinyl Chloride) and urethane
- Sealant is applied to the interior and exterior it will protect them from rust
- It will reduce NVH in car
- Primer
It can be water-borne solvent-bome or a poder used to improve • The primer layer is important for stone chip resistance
