Underbody Coating
UNDER BODY COATING
Underbody coating is a process of appling a dense cladding ( often based on rubber ) uniformly to the undercarriage of the automotive.under body coating provieds long term protection from corrosion to cars underbody, it also protects parts like internal body pannels, frame rails, and other inner cavities that are not physicaly accessible but are prone to corrosion. In Indian road conditions, a car underbody is most prone to corrosion, underbody coating provides long term protection from corrosion to cars underbody.
Underbody coating can be differed into 4 main types they are as below
1. Rubberized underbody coating
2. Wax based underbody coating
3. Asphalt based underbody coating
4. Polyurethane underbody coating
1. RUBBERIZED UNDERBODY COATING
This is the most used method of coating, its very easy to apply and generaly offers the best protection to the cars underbody. It cushions surfaces from moisture, dust, rigs, dents. this type of underbody coating is best used on quarter pannels,wheel whells and dries with soft rubbery finish.
2. WAX BASED UNDERBODY COATING
Wax or paraffin-based underbody coating 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.
3. ASPHALT BASED UNDERBODY COATING
Asphalt-based underbody coating 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.
4. POLYURETHANE UNDERBODY COATING
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.
