Underbody Coating

Underbody Coating

Automotive coatings are used for coating metal and plastic constituents of an automobile. Metal is the largest application segment and is expected to increase due to an increase in vehicle production. Plastic coatings are expected to increase at a substantial rate due to properties such as design flexibility, lightweight, cost reduction, corrosion resistance, recyclability, and greater durability.

Automotive coatings are a type of paint that are used on automobiles for protective and decorative purposes

Underbody Coating is one among Automotive Coating which is used for metals.

Underbody Coating

It is a process done on car's underbody as a protection against corrosion formation. Underbody coatings provide outstanding corrosion protection, even in locations with severe weather and excessive road debris.

It also protects parts like internal body panels, frame rails and other inner cavities that are not physically accessible but are prone to corrosion.

Benefits of Underbody Coating

• Rust Prevention: Ideally any additional underbody coating should be applied when the car is brand new and clean. Car manufacturers use thick paints and sealants for the underbody, but adding an underbody coat especially in coastal cities is useful. Salt water tends to corrode cars really badly.
• Sound Insulation : The thicker underbody coatings used on cars also act as effective sound dampeners. They can reduce road noise and tyre noise and make the cabin seem quieter – due to the sound absorptive nature of rubberized paints.
• Easy Maintenance : A uniform black underbody coating gives a car a clean look. It also makes the car easier to maintain by just hosing the underside down. You can be confident that slush build up won’t lead to rusting easily.

Downsides of Underbody Coating

• High Cost : Cost of underbody coating has come down, but is still expensive.
• Risk of damage during application : Care must be taken while applying underbody coating. This thick rubberized paint if not applied properly, can get into moving mechanical parts and cause premature failure – such as into the U-joint or CV joints in a cars propeller shaft or drive shafts. They can also hinder smooth movement of suspension components, if applied incorrectly.

New automobiles come with underbody coatings , is additional coating useful?

For a new automobile additional coating is not required as the OEM company provides the coating, but any additional Under Body Coating, if applies does no harm it just adds on a layer on already the existing Protection levels.
