Everybody is talking about the process of powder coating automotive parts. Powder coating has grown in popularity over the past few years for a number of reasons. How many of us see powder coating being used on shows like "American Chopper" or "Overhaulin'"? The general public knows from watching these shows that powder coating is out there. But what is powder coating and how exactly is it done? Anybody know?
Preparation is imperative in achieving a quality finish. The item being coated must be completely bare of any paint, dirt, oil, or any other substance. To achieve this, sandblasting equipment is used. If it is not possible to use this equipment, it must be done with chemicals or by hand. The items are then baked to remove any moisture from the metal. After all materials have been stripped off, the item is treated with a degreasing solution to help prevent corrosion.
Powder coating is a process by which selected items are coated with a fine powder of ground resin and pigment, which is basically ground up paint particles that form a powder-like substance. The items being coated are placed on a rack, which grounds the items. A gun is used to spray the powder onto the items. A large oven is then used to heat and cure the coating. Temperatures used to cure the items typically are between 400 and 450 degrees. Heating the items makes the pigments melt, gel, and then cure to form a durable finish. The finished product is a uniform coating. Powder coating can be used on steel, zinc, and aluminum as well as other materials. The quality of the finished product has the ability to outlast and outperform painted parts. A variety of up to a few hundred different colors are available to choose from. It also exceeds paint in resisting acids, solvents, impact, and abrasions.
