can powder coating handle the heat from calipers?

[wildturkey]

tried a search on this one no luck.

Looking at powder coating some 4 pot calipers..........been told I mite want to use proper caliper heat paint instead because the powder coating can't handle the temp.........is this true?

Any1 running powder coated 4 pots and had issues with heat?

Na bro, it would burn off or melt. You would need to get them ceramic coated.

It would be alot easier to use the duplicolor kit though. They turn out real nice and have the same sorta look as powdercoating.

Yeah I've used that caliper paint kit... good stuff.. lasts for ages!

[ReubenH]

I don't know. But i can tell you it doesn't take the heat of an intake manifold. Mine's all bubbled up.

[Munkvy]

Make sure whatever you use can handle 3-400 degrees. I have some temp sensors that mount on the outside of my calipers and they have seen 200 degrees on the outside alone. And I imagine rotors are seeing double that.

Na mate

Powdercoat wont work as the powder is heated when applied in an oven at around 300 degrees so anything close to that will cause the powder to melt again and fall off.

sweet cheers for the tips...............how much for that duplicolor stuff?..........from supercheap?

[Swindog]

You want engine paint for your manifold. The stuff that handles 1000deg C. Ripco have it.

That caliper paint is the best youll find. Put it on all of my cars bar the wrx which i used black spray can caliper paint with white enanmel paint for the lettering airbrushed on.

Unsure about Supercheap, but Repco does them. About $30ish

+1, is available at supercr@p in Brisb

It all depends on who does it as the brembos over in europe are powder coated. But yeah could be best to opt for the caliper paint.

[nzkaosnz]

yes is possible, ask the powdercoating guys.

[nzkaosnz]

but one needs to strip the caliper back (remove pistons etc)

I dont think they will be powdercoated, but there is other types of coating that could be used. When powdercoat goes on it needs static electricity to stick to the metal before being heated where it forms a hard layer that is quite thick so that alone would mean the pistons wouldn't fit back in and if you masked off the areas around the pistons and brake lines it will peal off because of the raised lip you would create by masking. On the other hand anodising would do the trick nicely but limited with colours and would require the pistons to be fully stripped down.

If you really dont want to paint them yourself with paint, give these guys a bell.

cheers yep I'm stripping them right down anyway and re-sealing them..........so thought I would look at paint/powdercoat options. I'll be getn them sandblasted to take off the scale. Painting with caliper paint looks the most cost effective option

I did mine with stp [i think] caliper paint and some kettle black heatproof for the lettering and other than brake dust making them dirty they are primo.

Heres what one guy did...http://www.benzworld.org/forums/w126-s-se-sec-sel-sd/1465942-how-powder-coat-rebuild-your-brake.html

the powder gets electrostaticly charged to the metal as is passes through the gun, the powder is then drawn to the earthed object. its is then cured at 210 degrees C for 10 minutes (metal temperature) as soon as it is cool enough to handle its ready to go. and its not that thick its about 80-100 microns if that. so its only a very fine lip.

and yes when it gets hot it does get soft but it wont come off as long as you dont go poking or proding it
