Underbody Coating
Under Body Coating (UBC)
Process of protecting bottom surface of car's underbody,also protect part like internal body panel,frame rails,also other inner cavity,that are not physically but are prone to corrosion.Ideally any additional underbody should applied whom car is brand new and clean.car manufactures are use thick paint and sealents,depends on cars and model underbody coating cost will defer
UBC - spray application of wax or rubber based composite onto entire bodyside of vehicle.its design to create prevent rust proof of layer between underside of vehicle and water, salt on rust.
Process:
Thick resilant applied to underbody or chasis, to prevent against damage from small stones,rapid chips ordinary paint,allow rust to begin.
Inclination angle and rotation angle was important. we have to ensure prevent any droplet.Heating chamber drained more droplets
Best Under Body Coating:
- Rust-Oleum professional grade under coating spray
- Fluid film undercoating(large project)
- 3M professional grade rubberized underbody
- Rust spary
- woolwax automotive undercoating
Types
1. Rubberized undercoating
2. Asphalt based
3. Polyurethene
4. Wax or Paraffin based
5. 3M
6. Penray
7. Rust - oleum
8. Volume
Rubberized Coating - prevent against scratches
Wax - big fight against moistures
Asphalt - Best for lorries and truck(less amount sound insulation)
Polyurethene - Clean up split,fracture, protection against corrosion
Advantages:
- Fight rust
- Absorb noise
- Rainforst
- prolong car life
For Maruthi swift ,based on indian road condition, also considering climate condition change,with behaviour approchs, usually refer ECSTAR ANTIRUST COATING, 3M types under body coating. For under body coating Inclination angle and rotation angle was important. 360degree rotation give max underseaking. we have to consider climate changes,polltion of atmosphere improper uses,etc. In india usually 2-3mm thickness, Mzx upto 3mm used. uniform coating also we have to ensure.
Modern Automotive Coating - Five Method
1. Pretreatment - Remove and clean the excess metal from surface to form appropriate bonding for protecting layer.
2. ED-electrodeposition-Anitcorrosion
3. Rust roof material-sealer/Pvc
4. Primer
5. Topcoat
1.Pretreatment-helps primer
2.ED-Involves dipping automobile and passes liquid
3.Lower Door section and rocker panel-where use pvc,urethene- use an anti chpping protection
4.Primer- fill smoothness,remove small improper things,increase durability.Main adhersion between E coat and base coat.
1. interior coating
2. exterior coating
3. cutting oven
5. Top coat
1.Base coat
primary colour pigment,3rd layer apllies to car.
Three different base coat: medium solids,high solids,water borne
2. clean coat
provide durability,environment etch,scratches, protect from UV ray.
