A lot of the ones I've spoken to shy away when you mention clear finish, maybe I'm ringing the wrong ones. I know of one company in Germany that can do it though!

 

I have a customer coming to collect his race car at the weekend, I'll see if he knows, he's in the thrermal barrier coatings game.

I work for one of/the the largest UK architectural glazing companies with our own powder coating plant.

 

Clear is not a problem (i've got a metal alien clear powder coated :) ) , its just un-common and you have to buy a bag of powder which is about £80+.

 

I'll check the heat it is stable at.

 

Paint manufacuters:

These 2 are the biggest/best:

http://www.synthapulvin.co.uk/

http://www.interpon.co.uk

 

Others:

http://www.omegacolours.com/ (same as synthapulvin but cheaper)

http://www.hbfuller.com

They will be able to give you a list of approved applicators, although you might find it cheaper from a smaller local company.

 

Heres a few applicators to get going with:

Barley Chalu 01953 602 771

Metallic Protectives 01926 491 811

Metalion 0208 965 4677

Supreme 01203 644 120

 

Maybe able to get something sprayed up at our works but i'll have to check, as we run batches and to do a one off small item is a pain - hence why most applicators probably shy away from it.

 

I'll post back with the temp.

 

Thought about anodising???

Sorry I was talking bollox.

 

You cant get ppc in a clear, well at least not in an architectural finish.

Partly because when you pre-treat the aluminium before application it goes a shity yellowy green colour which most architects dont like plus the pigment is used to offer part of the protection.

 

The polyester powder coat is baked on at 200 degrees, but is guaranteed upto 120, although once set it wont melt again, but it does burn/char. At 200 degrees you should be ok, but near 300 it will start to discolour and eventually burn off (class 0 spread of flame – ie. it doesn’t catch fire)

 

Depends on what you want to finish but I would suggest Plasticote Clear Enamel which I think is ok for upto 400 degrees I think, and they even do a stove enamel for 600 degrees. B&Q sell it.

 

God knows what myt Alien is finsihed in then :conf:

My rocker cover on my GTti is powder coated blue. Serious problem on that car is the high under bonnet temperature and my rocker cover has been fine and has not tainted or anything. The only problems with wheels is that eventually they start to bubble up from underneath. When they`re painted you`d just blast them and repaint. Once something has been powder coated its a nightmare to blast off again. I gave up and got another set of wheels.
