Powder Coating

[hcoles]

Phosphate coating prior to powder was mentioned.
In your opinion is an under coat (e.g. zinc phosphate) or other treatment providing additional corrosion protection advisable or needed? Maybe this is on a case by case basis depending on the part and the environment it will likely be subjected to.
Thanks.

Hcoles,

Phosphate definitely has its place but like you mentioned is a case by case need. I would recommend and do phosphate any metal that is Ferrous as it has a higher potential to rust so adding an extra layer of protection doesn't hurt. In addition to phosphating ferrous metals, I always blast as it leaves a far superior profile for powder adhesion.

I finished up some '70 Gran Torino parts. Valve covers done in Alien Silver with clear coat. I know they're not Porsche parts but it still shows the potential of what old parts could look like when refinished.

Here is what they looked like when received.

Hey fellas ists been a while since i posted up. I recently finished or am close to finishing my website and figured I would share with everyone.

This looks perfect for the CIS intake runners.

I had mine done in "chrome" PC and the finish does not stand up well to solvents. Basic gloss black and red seem to be able to take way more abuse without tarnishing.

Powder Coating should hold up to almost any solvent on the market. What happens with chrome powder if not done properly it will oxidize due to actual metal flake in the powder. To prevent this all chrome powder should be coated with a top coat such as a clear or candy color.

From what you describe it sounds like your chrome powder is oxidizing.

Some more parts refinished.

Our new friends at Creation Drum Company are always building some sweet drums for the discerning drummer. They reached out to us recently to do some custom powder coated snare drum hardware. They looked great when completed. http://byrnecoatings.com/custom-drum-hardware/

Thank you! I bet you are right.

You need to stick around.

Thanks Bob, I intend too. I like the members on here, they ask intelligent well thought out questions which I'm more than happy to answer.

Just looking at the pictures.

The Alien Silver has a green/purple hue that looks like it refracts in the light. You might consider to add this type of hue to a gold base to mimic the yellow zinc plating. My $0.02.

Hey there. You're just down the road from me (2 towns away in fact). I'd love to come by and see your shop some-time. Working on a potential suspension refresh this winter and that'll include a bunch of coated parts I need done.

Bob, Byrne earlier identified the above exhaust manifolds were coated with Cerakote, a ceramic coating, not to be confused with powder. Your observations are probably spot on about powder, but ceramics have different performance characteristics, one of which is their coating strength when exposed to hear, solvents, brake fluid, fuel and other automotive liquids. Byrne might want to add some clarity.

For some reason my images are not showing only links. I will try and fix.

Yeah the green/purple hue is from the LED lights in my shop. Powder is kinda tricky to try and mix.

I had a couple of questions:

- Which method do you prefer for engine fans - powder or ceramic coating?
- Will powder and/or ceramic coating adhere to JB-Weld? I've used it to fill some pitting and chips, but not sure if the either coating will stick to JB-Weld...

Either would really work but I would suggest powder as there are way more colors to choose from and it is certainly much more durable.

As far as JB Weld goes, I dont believe it will hold up to the curing temps of the powder process. Ceramic coating on the other hand shouldn't be a problem if it is of the air cure type.

I should also recommend if anyone is in fact thinking of repairing something that will eventually be powder coated, use a product called Lab Metal. Lab Metal will withstand curing temperatures and has done well by me.

I see you powdercoated springs and wheels...

How does it hold up on a spring? I would think the coating would crack from repetitive flexing?

Also, on wheels, does heating them cause any issues? I thought it could weaken the wheel?
