Powder coating and Teflon coating need of project
Answers
Answer:
- Both coatings are meant to impart some specific property to the item that is being coated. For powder coating, the goal is a protective layer that will keep the item from being damaged, although with Teflon, usually a non-stick surface is the property that is intended to be given to the item it is being applied to.
Explanation:
An electrode on the tip of the spray gun emits a charge that is passed on to the particles of powder when they pass through the tip. That charge causes the powder particles to start looking for something to latch on to and form a protective coating over it. So the powder coating process is very simple.
Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat. The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating of metals, such as household appliances, aluminium extrusions, drum hardware and automobile and bicycle parts. Newer technologies allow other materials, such as MDF (medium-density fibreboard)
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.
