Powder coating is like an ultra hard paint
that bonds extremely well to aluminum
. Like any coating, the metal needs to be clean and rust free. In most cases if the item you want to powder coat is used, then you would have the item sandblasted/bead blasted prior to the coating which most powder coaters do.
The item is usually hung from a conveyor with and connected to a positive electrical
charge. The dry powder is sprayed on and sticks because it has a negative charge. Just like paint
, you can vary the thickness. The item is then put into an oven
and the powder turns to liquid and coats the item with a very smooth finish. The finished product is so durable that you can hit it with a hammer and it won't easily chip or even scratch. There is usually a minimum charge of about $30 so I'll bring in several small items at the same time to have them done. If I am refinishing or replacing anything on my boat that is currently painted, I will ususally have it powder coated and should never have to worry about it again. Also, just like paint, you can get any color you want, even chromes, marble finish, textures, candy apple, etc
