Underbody Coating

Underbody Coating can be defined as a process in whic the car under carriage is sprayed or painted in such a way that includes the weld joints covers maximum under carriage surface and acts as a barrier from corrosion and helps to increase its life span.

Advantages of Underbody Coating

• Abrasion resistance
• Adhesion promotion
• Air holding
• Antimicrobial
• Flame resistance
• Increased duarability
• Waterproofing
• Weilability

Underbody Coating can be classified in to 4 types based on the purpose and type of material used

• Rubberized Underbody Coating
• Wax Based Underbody Coating
• Asphalt based Automotive Under Coating
• Polyurethane Underbody Coating

Rubberized Underbody Coating

It is the most commenly used underbody coating that prevents from rust and noise

For example - we can clearly distinguish the difference and importance of Rubberized Underbody Coating when you are driving on a tiny gravel roads.

pros

• Protection from scratches
• reduce undercarriage noise
• improves car life and valve of car

Cons

• Does absolutely nothing to slow down the spread of rust and corrosion sometimes when the air or moisture are trapped.

Wax Based Underbody Coating

It can be defined as a solvent containing an anticorrosive agent based on wax polymers.

Pros

• It fights good with moisture.
• most affortable option.

cons

• only drawback was it has to be replaced for every 3-6 months of time.
• catches fires when applied on moving parts and parts subjected to extreme heat.

Asphalt based Automotive Under Coating

The process can be defined as applying polymer or asphaltic material followed by application of reinforcing membrane.

Pros

• Best suited for lorries, trucks and heavy vehicles.
• greater Degree of protection.

Cons

• time consuming process.

Polyurethane Underbody Coating

Polyurethane Underbody Coating can be defined as coating that is mostly used for its durability and elastomeric properties.

Pros

• suitable to paint on wide range of substrates
• good for area with high salt exposure

Cons

• Expensive and time consuming.
