removing powder coating

[hubahuba]

I have some aluminum parts that I want to polish, but they are powder coated. Whats the best and easiest way to do this from a garage/home stand point. The parts vary from 8" long by 3-5" wide.

Sandblasting would be the easiest way. Buffing with an abrasive wheel would be the cheapest way, if you don't have a sandblaster.

Re: removing powder coating

I don't have a sandblaster and I do have the abrasive wheels. Some of the parts have nooks and crannies on them that the wheel won't reach. Won't heating the powder coating up then stipping it some way be easier?

Re: removing powder coating

We sell a product called "Clear Coat Remover" that will chemically strip the powder coat. No heating of the part required.

Re: removing powder coating

Will your clear coat remover work on powder coated zinc/pot metal parts? or will it attack the softer metal?

Re: removing powder coating

Should be fine. It won't attack the metal.

I have a few questions about stripping powder coating.

1) How large is the container of clear coat remover you sell, it dosnt say, does it contain caustic chemicals like normal automotive paint stripper, and can you guarentee it will strip powder coating?

2) What type of abrasive and grit do you suggest using to remove the powder coating if using a blasting cabinet? (IE 30 grit alum oxide, course grit glass bead, walnut shells etc)

Thanks for the help.

Its a quart. No we can't guarantee it will strip the powder. Depends how
thick it is.

It depends what sort of surface you want as a finish. I'd suggest a 120- 180 aluminum oxide. Walnut shells/glass bead are really more for polishing.

It's probably an anodized layer, but talk to your dealer to make sure.

There's lots of posts about this topic in the polishing forum.

powder removing

You can breakdown powder with many cheap items the cheapest is gasoline but not the safest. Paint thinner is not any safer though. Paint strippers are even nastier.Place the parts in a can of solvent of most any kind and leave there, stir and flip the part once daily until the part is completely stripped. Powder is not bullet proof it will fail to most chemicals eventually you can also carefully burn it with a torch this weakens the coating rapidly but be careful of the base material.Do not place in solvent when HOT! If you burn it first the soak time should be less than half of normal solvent time. You can also scratch or cut the coating in several places prior to soaking, this allows the solvent to creep under the coating and release the bond faster.This is not for removing anodizing.
