Underbody Coating

UNDERBODY COATING

Underbody Coating is a sprayable coating, which protects the under surface of the vehicle from corrosion rust underbody coating provides long term protection from corrosion to car's underbody.The underbody coating that is most commonly used on cars in India and supplied by companies such as 3M is a thick, rubberized paint that forms a 2-3 mm thick coating all along the underside of the car when sprayed on.

Here are some benefits of underbody coating.

1. Rust Prevention

2. Sound insulation

3. Impact resistance

4. Cold and heat insulation

5. Hides welds, repairs & bodywork with spray.

Types of underbody coating

• Rubberized underbody coating.
• Polyurethane underbody coating.
• Wax or paraffin-based underbody coating.
• Asphalt-based underbody coating.

Rubberized 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 coating:

This covering seals breaks and fractures in the vehicle’s underbody. It provides strong corrosion resistance and also binds to the metal.Unlike an asphalt-based coating, the polyurethane coating may be painted over.

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.It is also the most cost-effective alternative.

Asphalt-based underbody coating:

These asphalt-based undercoatings have a little bit of rubberised material that set up firmly and also helps in reduction in noise.The application of this coating, however, takes some time. Asphalt undercoating has the benefit of being less expensive.

Advantages:

1. Fights rust
2. Absorbs noise
3. Car life
