My experience with heat-stripping powdercoat

[BottleFed70]

I screwed up a fairly large part the other day, and being that it was a large part and had 2 coats, I wasn't looking forward to stripping off the coating.

I decided to try "burning it off".

It worked pretty good. You'll need an oven that gets darn hot tho. The powder coat started to bubble off at around 600*, but I'd reccomend you use an oven capable of 700* or you'll be waiting for a while.

I found that the powdercoat would start to bubble, and you could wipe big pieces off with a cloth (while it's still hot). Only problem is that it makes a lot of smoke... a LOT of smoke. You'll need to have your oven outside, or a shop with a really good exhaust fan.

The part came out looking like it did before coating, but with a little staining from the smoke. A quick 2-minute media blasting was all it took from there.

Just get an oven off craigslist that has a self clean feature - IIRC they get up to like 1200 degrees.

We usually do steel @ 800 for 4 hours, aluminum 700 @ 5 hours. Turns the powder back into powder
