Underbody Coating

Under Body Coating (UBC):

Underbody coating used to prevent car bodies against rust,corrosion and moisture.

Automotive Coating Process:

1. Pretreatment
2. Electrodeposition (ED)
3. Under Body Coating (UBC)
4. Primer
5. Top Coating

1. Pre-treatment:

Removes and cleans excess metal and forms an appropriate surface structure enabling bonding of a corrosion protection layer.

2.Electro Deposition Coating (ED)

ED coating provides rust and corrosion protection.

3.Under Body Coating (UBC)

Rust-proof materials: Sealer/PVC/Urethane

Underbody coating (UBC) and seam sealing using PVC and urethane.

The sealant is applied around and inside the doors, hood, trunk, and front dash and onto the exterior and interior of metal joints and outer area of the back wheel well.

4.Primer

It can be water-borne, solvent-borne or a powder.

These primers are used to improve adhesion between the E-coat and topcoat, provide chipping protection, enhance paint appearance and also be environmentally compatible with emission regulations.

5.Top Coat

It consists of two layers—the basecoat and clear coat.

The basecoat contains the primary colouring pigment

Clear coat provides a protective coating against environmental effects, corrosion, and UV light degradation promotes unmatched colour retention and provides a smooth unblemished even finish.

Types of Under Body Coating:

Underbody coatings are categorised into various types based on the type of material used and also the cost of the material.

Rubberized underbody coating:

These coatings are easy to apply and offer sound-cushioning as well as protection from dust, moisture and dents. The coatings are safe even to use on wheel wells and quarter panels and when it is dried forms a soft rubbery finish that prevents further rust and moisture seep.

Polyurethane underbody coating:

This type of undercoating is a lit a bit quicker and easy to apply. This type of undercoating often comes in a canister ready to preload into application gun. This type of undercoating always requires surface preparations before applying.

Wax or paraffin-based underbody coating:

Wax or paraffin-based undercoating will be the cheapest and quickest option available in the market. But these coatings last only for one year of duration.

Asphalt-based underbody coating:

The above-mentioned undercoating is mainly used for light commercial vehicles. For vehicles such as trucks, buses, vans etc. asphalt-based undercoating is used for sufficient protection against rock chips and moisture. These asphalt-based undercoatings have a little bit of rubberised material that set up firmly and also helps in reduction in noise.

Benefits of underbody coating:

• Minimizes Sound: It minimizes the sound from underneath the car resulting a noiseless, smooth driving experience.

• Heat Insulation: It insulates the interior of the car from extreme temperatures from beneath the vehicle providing a comfortable cabin experience.

• Anti-chipping property: If any stone hits the coating it does not get chipped away hence protects the underbody from exposure to water.

Fights Rust

• Reinforcement
  

  If your car comes with stock underbody coating, using another coating on top of it, is not going to hurt. It will offer additional reinforcement, protecting the underbody from water, road debris, gravel and small pebbles. There would also be a lesser chance for the factory coat to flake away.
