What is Powder Coating?

Powder application is very simple.  The powder is applied to an object using an electrostatic gun.   Compressed air pushes the powder out of the gun, past an electrode which gives the powder a positive charge.  The object being coated is grounded so the positive powder particles are attracted to it.  When the object is completely covered, the ground is removed and the object is put into the oven to be baked. While in the oven, the powder goes through a chemical change where it becomes free flowing and forms a ‘skin’ around the object.  After cooling, the powder is ‘set’ and forms a hard finish.
