Stripper

[PCT17522]

I just posted a new thread like an idiot without looking at other threads first. Sorry.

I am specifically interested in stripping epoxy. I've been trying various things for over a year now and have kept coming up short. My big problem is stripping aluminum parts that have been pretreated with a yellow chemical film (MIL-C-5541, Class 1A). Does anyone have any experience with this or stripping epoxy in general? If it helps anyone else out there, I've found that Stripoxy2800 from General Chemical Corp will strip epoxy off of ALMOST anything. It mostly falls off in sheets (when left for several hours at about 185*)...except if there is this stinking chem film.

The chemical coating is out of my league, but would blasting take it off?

I have used a palm sander with various grit sizes to remove the coating from larger flat surfaces. I haven't tried to blast all of the coating off. I do blast the residual coating film that is left after the strippers don't work completely. I think, given the delicate design of the parts, and the softness of the aluminum, and the hardness of the epoxy... and the thickness of the coating (about 10 mils) that blasting would probably ruin some of the part before all of the coating was removed.

I'm not sure what exactly the "chem film" is, but it's purpose is to enhance adhesion... and boy, does it.

I realize that this is a very specific problem. I'm going to try again to see if I can get some info from the epoxy suppliers. Maybe they have a better idea what will strip their materials. I keep getting referred to the 'aircraft stripper', but IMHO, that stuff stinks.

I'll post any success that I have.

i got the solvent kleene 1012 sample. holy $hite that stuff is sweet. i left a powder coated part in it for 17min, gave it a quick giggle, and it came out nearly spotless. it took a quick wipe with a paper towel to make it spotless. no real odor, doesn't burn my skin (not that i dunked my hands in it). neat stuff.

I'll admit the d-zolve 1012 works well. The only thing I don't like is that you have to filter it occasionally. This stuff actually dissolves the powder and sludge will build up in the bottom of the container you use it in. The stripper continually works on that sludge and makes it less and less effective.
Other strippers that sheet the powder off in chunks are easier to work with. Just dip out the chunks or add some type of mesh tray in the bottom that you can just lift out.

I am about ready to take the expense to get 10-20g of stripper. Tired of ising aircraft stripper all the time.

Has anyone used Miles Chemicals? They make a heated and a room temp solution. I am thinking of trying the room temp stuff. Let parts soak in a laundry tub. The type os plastic sinks with legs, then drain the stripper through a strainer/filter for the sludge

We get some stuff from "endura" and it works pretty good. Can get you more info if you want. About $165 for 5gals I think.

Has anybody tried positive 170 from technichem ?
It is a powder that you mix with water and does not need to be heated

What are you using Harley?

At first i was impressed with D1012, but after I read your statement about it getting less and less effective with time as it eats the powder in there I went to check. I dunked a part in the tank to see, and it took a solid day to get it all of the powder off, and I had to scrub it with a wire brush, then sand blast it. I guess your right Iv'e only had that stuff since Feb, and done a dozen or so saverage size parts.

Whoever said d1012 doesn't harm your skin is wrong. I had a pinhole in my gloves in two of the fingers, and two days later I had skin drying and flaking off everywhere. And it cracked and burned.... Its nasty stuff.
