How heat resisitant is powder coating?

I was looking to get some color on some engine brackets and was thinking of powder coating them so they hold up. One of them is really close to the exhaust manifold. Will the powder coating hold up to this heat? Thanks

 

What color?

I think you can get flat blue and white in ceramic coatings. I know for a fact you can get bright silver finish and gloss black in ceramic high-temp. Look up Cermakrome or Nitroplate. Maybe a Google search will turn up more colors in Ceramic or Porcelain coatings.

 

You can powdercoat just about anything on an engine, except the exhaust manifolds. I had my engine block, heads, intake, everything on my 348, including the generator brackets that bolted to the headers, powdercoated. Haven't had any problems from heat, even after 15000 miles. The only thing that did affect the coating was antifreeze, which caused some discoloration. The headers had to be HPC coated.

 

I think Powder coating melts at 450 degrees. Take a temperatue reading where you want the coating maybe? Ceramic coating holds up on pipes over 1600 degrees.

 

depends on the powder..most TGIC and polyesther powders cure between
385-400 degrees..if it's not in direct contact with the headers or exhaust manifold it ought to be alright..not a whole lot of heat gets by convection, if you're nervous about it you could ust a hi temp exhast powder..but the colors are severely limited..you can have it any color you want, as long as it's black or silver..<G>

A friend of mine has a powdercoat business, and the last time i was in the shop we were talking about header coating's.
He said he now has a product that it resistant to heat up to either 1200 or 1500 degrees..
I'm not sure what color's they were though..
I was interested in the white for a set of header's, so i believe that was one of them.
Maybe a shop around you may have the same product.
