Underbody Coating

UNDERBODY COATING

1. Undercoating coating is like a primer coating given to a building before painting
2. BiW is inclined in a paint bath at an angle at which the BiW is inside the ED bath
3. These are decided with weight and facility of the plant
4. Body rotate at some angle why because ED droplets are completely let out from BiW, not even a single droplets found in BiW
5. ED is given in a effective and proper manner then only body observes paints and also it gives resistance to the corrosion
6. BiW rotates at 360 degree to have good contact with ED and also the body provided with some holes to let out the water to get complete drain
7. Then BiW goes into heating chambers to evaporate the water droplets
8. Again BiW dip in a primer coating in the primer region before painting
9. BiW enters into the colour painting coating region
10. After that BiW enters into the underbody sealant region which is included in Benchmark reports
11. In most of the Luxury cars spot welded region coated with sealant but in low cost cars does not coated with sealant region
