Underbody Coating

                                                                                                           UNDER BODY COATING

1. What is Underbody Coating?

Underbody coating is usually a dense cladding  applied uniformly to the undercarriage of the automobile. It is normally sprayed or painted on when the car is just out of the dealership and is clean.

2.Why underbody coating is needed for automobiles?

The main purpose of underbody coating is to prevent the metal components that are placed underground of the car , the dust and other effect of  damages caused by the our sourounding  environment by rust and corrosion.Poor roads, rocks getting thrown from the tires and denting the metal, and corrosion from road salt in the winter all play a huge part in the damage or decay of a vehicle's underbelly. 

Standard of Coating Thickness

• 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.

Instruments to measure Underbody Coating

• ELCOMETER

Primarily used in multi-coat procedures and non-metallic substrates, Elcometer offer a complete range of paint inspection gauges (PIG gauge) designed to measure the thickness of single or multiple layers of a coating.

• NITON XLT

Is ideal for analyzing metal alloys, detecting soil contaminants and carrying out mining exploration. Its benefits include advanced light element analysis, real-time results and true lab quality performance.

Types of Underbody Coating

• Rubberized Underbody Coating

It is easy to apply and offers sound-cushioning as well as protection from dust, moisture, and dings or dents.In addition to your undercarriage, rubberized undercoating is also safe to use on wheel wells and quarter panels, and dries to a soft rubbery finish that prevents further rust, damage, or moisture seeps. The coating can be painted over and, if necessary for bodywork, can be easily removed with an undercoating removal spray.Overall,rubberized coating is generally the best option for protecting your vehicle's undercarriage, as it provides the simplest and best protective measures against rust and moisture.

• Wax Based Underbody Coating

This – more or less – ephemeral undercoating will wear away in a few months’ time. On the upside, wax-based undercoating puts up a big fight against moisture. It is also the most affordable option out there.

• Ashpalt Based Automotive Underbody coating

Best suited for lorries, trucks and large vehicles this provides a greater degree of protection compared to rubber-based coatings. However, asphalt-based coatings contain little amounts of rubber for sound-insulation purposes. The process of applying this coating is a bit time-consuming though.

• Polyurethane Underbody Coating.

This coating closes up splits and fractures on the underbody of the vehicle. It offers up good protection against corrosion and also bonds with the metal. Unlike in the case of asphalt-based coating, you can paint over the polyurethane coating.

ADVANTAGES OF UNDER BOADY COATING

• Prevent from Rust and Corrosion

It plays an important role in keeping corrosion at bay. Underbody coating can come in handy especially if you live near the sea, where there is too much humidity, and rusting is just one of those everyday things. You should also seriously consider undercoating if you reside in a place where it snows in winter.

• Reduces Noise vibration Harshness levels

Thick undercoating can soften the noises that reach the cabin. Since the undercoating is often made up of rubber it absorbs some of the rackets. The occupants of the car could spare themselves of the road noises – at least up to a certain extend.

• Protect Paint of Automobile

Running on the highway or while pacing through a city road, you will often encounter sharp gravel or any other unattended object hitting the belly of your car with high momentum. This scrapes and chips off the metal from down below. A thick layer of Underbody Coating definitely comes to aid and minimises the effects of such contacts on the body.

• Protects Major Components

A lot of indispensable parts of a car are left exposed like the Engine, silencer, etc.We can left these parts to go damage with rust and corrosion. So underbody coating can comes to play a vital role on protecting the major components. 

Disadvantages of Underbody Coating

• Its an expensive process increase the budget of the vehicle.
