Any ideas what chemical removes this stuff?

I'll give you a clue.. It's not Caustic Soda or Hydrochloric Acid.. :(

blast them.

Thanks, but no thanks. I don't wish to blast it. :)

"Jasco" paint remover works wonders (just about any paint stripper),
Remember to wash off the paint stripper with TSP (trisotium phosphate) to remove the wax before painting. Or permatex gasket remover. Or can you get methyl chloride? Its outlawed in the states, but might be available where your at.

I have tried methylchloride based paint stripper. It also had no effect on it at all.
A few brands advertise on the net with a search, but none available down here.
I'm hoping to find the active chemical so I can just go buy it if available..

Abrasive blasting or baking in a industrial oven is the only way to remove powder coating. Look in your local phone book under powder coating and give them a call. Some powder coaters have the equipment to remove the old coating.

I like powder on some parts and some I don't. This is one of the reasons I don't like it though!

As mentioned above go to a local powder coater and ask them.

blast them.
Dale has the only answer...ya gotta blast it. That's why anything PC is there to stay.

Thanks, but I disagree. :)
Yes, blasting will work of course, but it's not the only answer.
There are products and raw chemicals available that will remove powder coat. Some time ago, I had some aluminum valve covers and a subframe & A-arms dipped professionally in something that worked beautifully.
I'd like to find out what chemical. Naturally it's the trade-secret of the company that did the stripping, so they didn't tell me.
The powder coating places I spoke to also didn't know. Some said caustic soda which I know doesn't work, at least at the ambient temperature I tried.

There is something!

(A clue might be brake fluid once ruined the finish of powder coating on my old subframe..)

What is it on, is the metal thick or thin?

I do a lot of P. Coating, and sand blasting is actually one of the hardest ways to remove it . Because the friction from the sand causes the coating to melt. It's like trying to blast something with grease on it! The quickest way I found was aircraft stripper. Just my 2 cents.

Blackout - Some use an acid dip!


Scott

I'll see if I can find some aircraft or marine stripper.

The coating is on the USA-made repro battery tray. It really annoys me that they don't just prime it and sell it that way. Heaps of foreign repro brackets are sold coated like this too. A real PITA. :mad:

Not everyone wants the incorrect gloss black finish that they can't easily remove in order to paint correctly.

Some gasket stripper had a go at it.

It's CRC's brand and has Methylchloride, Liquid petrolium, Methanol and Xylene in it..
The methylchloride paint stripper did nothing on it's own..

My local shop bakes the parts again and the old powder just brushes off, I'm not sure what temp they have to go to or for how long though. I know sand blasting takes forever...

Checked yesterday with a bud who does a lot of industrial PCing, and he said, as did Mike, that baking it is the only effective way to take off the coating. Another friend in Calgary , who got out of the business said that some of the chemicals that might be used are pretty severe to work with, so be careful if you use them...more so than the reg strippers.

capt

I was able to remove most of the coating by applying heat.
Apparently 400-450F is required to bake the crap on, and you need around 600F to burn it off.
An oxy/acetylene is the only way for me to get that kind of temp, and a great way to distort the parts with localized heat.

I'd still love to know what chemical that I took my stuff to company used.

BlackoutSteve,

Depending how thick of an application was applied, you might try a 3m abrasive disk on a drill to get the shine off, then use aircraft stripper. This is the only way I can get the new factory applied powder coat off a Harley frame.


Good luck,
Scott

The answer I gave is the correct one.
Blast it. If you can not blast it or don't want to blast it, then you can not remove it.

If someone really has a proven, tested, surefire method. I would like to hear it. But even my blaster says, NO.
There is no reliable way to remove it.

If all you're concerned about is the color, you don't have to remove it to paint over, just sand it and paint it the color you like.

Call companies that sell powdercoat paint. They have a paint remover that works on powder coat. It´s expensive but it works excellent.

I've had success blasting this stuff off in the past. I just did a tray that was coated. It actually came off pretty easy. I do have a pretty nice blaster unit to use and we use Aluminum Oxide media. After blasting it is ready to prime/paint. Turned out well. Good luck.

Yes PC is a pain to get off, we usually burn it with a torch to crisp it up, then blast it.......all this hassle and PC isn't muchmore durable than paint. :(

Steve,
I am curious. You have been asked what parts you are trying to get it off and you have never stated. What are you trying to remove it from????

cook it, you basically are burning it off, your local P/C can do it, it still takes some elbow grease to brush or scrape it off. I have not found a chemical that will work, but I am sure there is something out there, not sure I would use it thought, don't think I could even get it here in CA

I third Aircraft Paint Stripper, don't waste time just get the industrial stuff and be careful with it.

Either that or find someone with a big hot tank and buy em a few beers to let you put your item in it.

Most (all?) repo metal parts I know are black e-coat or bare metal, not PC. Are you positive that your batt tray is PC?

No I'm not. I just figure it's a powder coat because it's as resilient as other powder coatings I've tried to remove.
Maybe you're right, maybe it's this other e-coat stuff..

IS ANYONE ELSE CURIOUS ABOUT WHAT HE IS TRYING TO REMOVE THE POWDER COATING FROM????????

Also, the answer that Jimmy gave above about painting over if you don't like the color is one that works fine.

Repro battery tray.
Post # 12.
Doesn't like the shiney look on it that it came with. Wants more correct look.

The part that the coating is on, is irrelevant to the question. (Why so important to ask with bold uppercase I wonder..)

Anyway, it's not just the battery tray that this full gloss crap come on. It's loads of repro brackets and parts.
