Hi there guys, I recently stripped my Death Korps of Krieg using acetone free nail polish remover and it works a dream except I have noticed that some of the flimsier parts of the models, (most notably the medicae servitor arms) have become floppier than over cooked noodles.

Does anybody know how to remedy this, was thinking maybe heating and quickly cooling in cold water or something but I have no idea if it will work, thanks in advance ladies and gentleman.

it does not sound like the model bent, its now not as strong.

what is the active ingredient in the nail polish remover?

if it uses alcohol instead of acetone, you effectively ruined the models. resin react badly to some compounds, alcohol being one. it will make the resin rubbery and flexy, and as far as i know, you cant reharden the resin.

Tend to agree with your assessment of the described symptoms...though disagree with the final prognosis.

Resin will often absorb chemicals into the polymer matrix. Depending on the chemical this can cause it to swell, get bendy or crumble into dust. Luckily, it didn't crumble to dust. Overtime, the chemicals will leach back out of the resin - returning it (largely) to its original state (though often more brittle due to the expulsion of plasticizers).

This is one of the reasons I caution against using "acetone free nail polish remover" or other generic terms like that with...much of anything. You need to know what the active chemicals are in the material in order to know for sure it is safe. The only thing you know about that is that it doesn't have acetone. Once you know what the active chemical is (found on the ingredients or MSDS for the product), you can work backwards from there to determine a fast leach process (basically to draw/drive out the chemical you don't want). The other option is to give it time. Normally it will come out on its own over the course of a month or so, sometimes more depending on the chemicals involved and thickness of the soft resin.

Is there any way to speed this process up?

No clue without actually knowing the particulars (which is what I said above...). There will be "a way" - however, it might be beyond the scope of your average home user depending on the chemicals involved.
