Electrostatic Application

Electrostatic Powder Coating, In this method of application, a high voltage generator is used to charge an electrode at the tip of the powder gun. 

This creates an electrostatic field (or corona) between the gun and the substrate. Gas molecules in the air pick up electrons emitted from the corona. 

This negative charge is, in turn, transferred to the powder particles as they are propelled from the gun head towards the substrate. The charged powder particles are deposited on the earthed substrate.
