Underbody Coating In Automobile

UNDERBODY COATING OF AUTOMOBILES

OBJECTIVE:

To study about the Underbody coating usage of automobiles industry.

INTRODUCTION:

It’s important to protect all aspects of your car from damage, rust, decay. All the moving parts are work together to form a well- functioning and safe-to-drive whole, and it’s easy to forget about the bottom of car underbody. That’s where car undercoating comes into play.

Underbody coating helps protect your vehicle against rust and corrosion. But there are factors to consider for corrosion happens Poor roads, rocks getting thrown from the tires and denting the metal, and corrosion from road salt in the winter all play a huge role in the damage of the vehicle.

TYPES OF UNDERCOATING:

There are variety of the underbody coatings available. Depending upon the level of damage and how much protection you want for your vehicle will determine which type of undercoating you choose.

• Rubberized Undercoating
• Polyurethane Undercoating
• Wax or Paraffin based Undercoating
• Asphalt- Based Undercoating

1.RUBBERIZED UNDERCOATING:

• Rubberized vehicle undercoating is easy to apply and offer 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 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.

2.POLYURETHANE UNDERCOATING:

• Polyurethane based sealant undercoating is a little bit quicker and easier to apply. Its is ready to preloaded in canister.
• This type of sealant works by seeing into all cracks and seems, displacing salt and moisture and oozing around rusty areas to bond with and protect on unoxidized metal.
• It requires a little bit more surface prep work before applying- sanding and applying an etching primer to bare metals before using are generally recommended.

3.WAX OR PARAFFIN BASED UNDERCOATING:

• A Paraffin based undercoating will be cheaper and quicker option available with which to protect the underbelly of your vehicle.
• However, keep in mind that it will wear off quicker than other types of undercoating and will need to be stripped and reapplied at least once every year.
• Wax based undercoating never truly harden. During application, they drip or flow into seams and cracks to provide protective properties.
• They are usually available in a spray gun in canister or aerosol can and offer at least a base protection in moderately humid climates.

4.ASPHALT BASED UNDERCOATING:

• For standard vehicles, any of the aforementioned types of undercoating will provide sufficient protection. For large trucks and heavy machinery, asphalt – based undercoating provides a bit of extra durability against rocks, chips, and moisture.
• This Coatings are Generally Contains a little bit of rubberized material that sets up firmly and also soften noise.
• In this type of undercoating also needs more cure time than other three, and is not paintable, making it best to use only for underbelly.

ADVANTAGES OF UNDERCOATING:

• Believe it or not, very 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.
• If your car comes with stock underbody coating, using another coating on top of it, is not going to hurt. It will offer additional reinforcement, protecting the underbody from water, road debris, gravel and small pebbles.
• Good undercoating not only defends the underbody from corrosion but also protects the engine and transmission as well.

DISADVANTAGES OF UNDERCOATING:

• A used vehicle may already have residue on the bottom of the car or even have spots of rust and corrosion.
• Undercoating will not help you if corrosion already exists and the corrosion needs to be removed first before it can be applied, which can be expensive for you.
