preface of powder coating and teflon coating
Answers
Teflon coating also known as anti-rust coating, is done on the surface of the car. Teflon is chemically synthesized from fluoropolymer. It is a brand originally owned by Dupont, but now has become generic to the category of PTFE paint sealants. This protects the car’s painted finish and offers a brilliant shine, doing away with the problem of corrosion and wear and tear in high as well as low temperatures, keeping the vehicle like new for a long time.
Teflon coating is also done under the body of the car. The under body 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. You also get a thinner clear coat under body coating which is like a lacquer that coats the entire underside of the car. Some even inject rust-preventive coating material into crevices such as the bottom of doors and door sills, to protect them from rust.
