Is it OK to paint a magnesium fan?
Posted by: jetcat ()
Date: February 21, 2018 06:52AM

I've seen lots of pictures of painted fans but wondered if that was really a good idea. Especially if powdercoated that is pretty heavy paint. How critical is balance? This question comes from a guy that use to balance rotors for micro jet engines....

Any comments on this?

They do not powdercoat particularly well as the material is a little porous and can bubble. I have been painting them for years using high quality spray paints made for wheels. Balance is not a big issue on these as long as they are not way out which I do not believe is possible to cause with even poorly applied spray paint.

Thanks Ted!

Yes, I figured balance wasn't too critical since I took of about a pound of grease off it. What type of primer do you use? I presume you preserve the anodize and do not glass bead it first.

If not powder coat then I would probably use a single stage urethane (because I already have it in the color I want).

I've had a dozen powdercoated without issue. Sandblasted then powdercoated. My powdercoater is keen enough to notice cracks after sandblasting and we've scrapped a few for that reason. Never a problem with balance or adhesion. The oldest one has been in service for almost 20 years. Nothing wrong with paint either; just be sure to inspect for cracks.

I would prefer to powder coat, easier for me and they have a close match for Regal Red. Would't trust them to sandblast, I would do that. They do tons of stuff for my company and generally do good work but they're kinda rough.... I'll warn them about the porosity and see what they say.

BTW Craig, your bottom picture is exactly what I want to do.

I always blast them and paint them. My powdercoater felt they would not coat well maybe we will try the next one. I have had very good luck painting them with Duplicolor spray can wheel paints. Epoxy primer first is a bonus I guess, but this paint seems to adhere either way

I have powdercoated these for years and never an issue.

Looks nice. Be prepared to sand or round-file the ID where the fan fits over the bearing hub.
