Powder and Teflon Coating Process
Feb 08,2014

The main goal of both powder and Teflon coating process is quite similar, but the processes we used to do those is a little bit different. Both processes want to create a new defined property to the specific item on which they are going to be coated. In powder coating it want to protect the item being damaged where as in Teflon coating it creates a non sticky layer or surface on the item it is being coated.

Powder Coating Process:

In this process the thing which we are using for coating is simply a powder.It is generally sprayed on the surface of the item and then dried to form a coating.In this way we do powder coating.Here comes the question how the coating works:

First the powder is filled in the feeder unit for the spray gun. Compressed air inside the feeder diffuses the powder,so that it acquires a state of liquid even still technically it is a powder.

The gun sprays the powder by using high velocity air and propellling the powder from the feeder to the gun.Guns can spray upto 10 to 25 feet.When the powder comes out of the gun looks like a cloud moving toward the item to be sprayed or coated.

An electrode placed at the tip of the spray gun emits a charge that is passed on to the particles of powder when they passed through the tip. This charge makes the particles to start looking for something to latch on to and form a protective cover or coating over the surface of it.

In this way powder coating will be done,after it has been applied,it is baked on to the item. Powder coating looks similar to that of painting job,but with many benefits from that of ordinary painting. The powder which doesn
