Underbody Coating
UNDERBODY COATING PROCESS
Underbody coating is used to prevent all car components from rusting and corrosion and it also helps to protects from dust and moisture present in our atomsphere.it also protects rocks ,sand which comes from tyres and denting the metal and salt from rain water in monsoon season it plays a major role to prevent damaging the underbelly of a car.it is used to protect from poor conditioned roads
PROCESS OF UNDERBODY COATING:
Pre-treatment: In this process remove and clean the excess particles present on vehicle such as excess metal or dust.make appropriate surface to enable a bonding between corrosion protection layer.
Electrodeposition - The electrode deposition coat provides rust and corrosion protection. It is done over Body in White. The metal underbody and the frames are coated to prevent corrosion. While areas that are not coated are primed before applying the additional coating.
Rustproof materials [Sealers/PVC] - The underbody coating has some specific advantages when compared to that of electrode deposition. The underbody coating has noise reduction, vibration reduction, and anti chipping properties in addition to that of underbody coating.
Primer - The primer is applied over the top body of a car to improve weather resistance, improve appearance, chipping resistance, improve adhesion between electrodeposition coat and topcoat, and reduce the volatile organic compounds that cause the atmospheric pollution.
Topcoat - The topcoat has two stages, they are base coat and clear coat. The base coat has the primary coloring pigment, while the clearcoat provides a protective coating against environmental effects, ultraviolet light degradation, unmatched color retention and a smooth even finish.
Types of Vehicle Undercoating
Rubberized Undercoating
Rubberized undercoating is easy to apply, and generally offers the best protective coating for your car’s undercarriage. It cushions surfaces against moisture, rust, dings, and dents. Rubberized undercoating is safe to use on quarter panels and wheel wells and dries with a soft rubbery finish.
Asphalt-Based Undercoating
Asphalt-based undercoating offers a higher level of protection suitable for large trucks, recreational vehicles, and heavy machinery. It’s formulated with some bits of rubberized material to aid in noise reduction. It offers extra protection against chips and moisture but is not paintable and, therefore, only suitable for undercarriages.
Polyurethane Undercoating
Polyurethane coating is easy to apply and works by sealing up cracks and seams. The compound displaces salt and moisture and protects the unoxidized metal from rust. It’s often sold in canisters that are ready to preload into an application gun. It, however, requires some surface prep work before application, like degreasing, and applying an etching primer to the bare metal.
Wax or Paraffin-Based Undercoating
Wax or paraffin-based undercoating sprays are the cheapest and quickest options available. However, their results don’t last long, and you may have to apply a fresh coat after only a few months. In addition, the wax isn’t very adhesive on a metal surface. Its main advantage is that it seeps quickly into cracks and seams, and offers moderate protective properties against moisture.
Advantages of underbody coating:
- It extends the lifespan of your car components
- It reduces the loud road noise
- It prevent from stones and paint chipping
- It protects Against Rust & Corrosion and also vital component of car
- It reduces NVH (Noise Vibrations Harshness) Levels
Disadvantages of underbody coating:
- It is less helpful if corrosion is already present.
- It works best on new cars.
- Most vehicles make it five years before corrosion begins to show.
- It adds weight to the vehicle
- An undercoating is not impervious to damage.
- It must be reapplied every 3 to 5 years for the best results
