Powder coating wheels. How?
Thanks for the offer. If you are talking about the ones off the MR, I am not really a fan of the styling of those.
Powder is indeed a more durable coating than liquid AND electrostatics can help to build a thicker film than liquid without sagging. This is within limits of course and is powder dependent. Typical thickness is 2-3 mils for many applications. Both liquid and powder must typicaly be thicker than 1 mil (25 microns) to cover a metal surface - especially with lighter colors. However, it is not necessarily the "thicker than liquid" coating that gives powder its more durable finish. It is the fact that the polymers in the powder will gel, cross-link, and then fuse during the cure cycle in the oven. This is what gives powder a more durable finish that is perfect for wheels and other metal surfaces that see harsh conditions. Electrostatics simply charge the powder and help it to stick to the conductive metal part - and of course build thickness as required and within limits. Curing is what gives powder its hard and durable finish.
