Powder coating is an industrial finish..has always been used on things like heavy equipment(cranes,bulldozers,combines,etc..),big factory equipment,exterior structures that see a lot of wear and tear or weather, gym equipment and all the fixtures,shelving and racks you see in just about every store on earth.
The reason for the use on all these things? Durability.
Powder Coating is much more durable than paint..it can take a beating and not peal or chip off like paint. UV resistance is better as well as resistance to salt corrosion and petroleum or acid based materials.
To sum it up in simple terms...Positively charged colored powder is sprayed onto a metal part that is grounded. The powder is attracted to the part and then the part is baked in an oven till the powder is cured. Basically it's like melting plastic over a part.
Wheel companies like BBS, OZ, RONAL and HRE actually base coat most of their wheels with powder coating as a sealer. Then paint and clear coat over that.
I think it is more popular now because of TV... All those shows like American Chopper or American Hotrod showed the public that powder coating can be used on more than industrial items.
I think half of my kitchen is powder coated.lmao.. cabinet hardware ,stove burner covers, containers, chairs....
THE CONS OF POWDER...
Primarily for metal parts only. Because it all has to be cured in an oven, some parts can not stand up to the heat. Some plastics, glass and wood can be coated with the proper technique. But not all....
All the BMW intake manifolds and valve covers that are called plastic are actually made out of glass filled nylon. They can be coated because the melting point of them is high, but the technique is a royal PITA and is not worth the hassle. I have done a few of the M50 intakes and S52 covers but they are a pure nightmare to get right and not worth messing with.
Hope I covered it all.... Dave
