Brother Immolator Posted September 22, 2011 Share Posted September 22, 2011 I have a bunch of plastic marine stuff that i got from a friend.The problem is that he had soaked them into something(IDK what really)to remove the paint. The paint is more or less gone but the bits are like chewing gum right now! I cant believe it really,you can literally bend them,stretch them,even remove the fingers from a termy power fist one by one! So my question is:Can something be done to reverse this and return them to their original state(hard state?)or are they gone forever? Link to comment Share on other sites More sharing options...
Grotsmasha Posted September 22, 2011 Share Posted September 22, 2011 Sounds like a chemical reaction, which will ne hard to reverse. Maybe try the freezer? I've really no idea, at all.. Jono Link to comment Share on other sites More sharing options...
Sgt. Tiberus Satio Posted September 22, 2011 Share Posted September 22, 2011 You can try heating (seasalt?) I forget the actualtype of salt for this, but you heat the salt, put the model in it for a certain time, then instantly dip in cold water. Similar to pouring hot wax into water.. I believe there is a topic in the tutorials for this, but I will have a look when I get home on my favorites and see if it's still in my inbox.

red_starrise Posted September 22, 2011 Share Posted September 22, 2011 How long have they been out of the chemical? Are there any other reactions such as discoloration or actually melting of the plastic anywhere? Link to comment Share on other sites More sharing options...
Brother Immolator Posted September 23, 2011 Author Share Posted September 23, 2011 How long have they been out of the chemical? Are there any other reactions such as discoloration or actually melting of the plastic anywhere? About a day or so,no discoloration or melting,they just became like rubber.I tried the freezer and it works only temporary,after they get into normal temperatures they become ruberish again.

Grotsmasha Posted September 23, 2011 Share Posted September 23, 2011 Being that they return to the rubbery state, 1) are they legitimate GW parts or some dodgy rubber-remoulded Russian stuff (I've been caught out....more than once), 2) If GW authentic, it really sounds like a chemical reaction now and will *probably* be irreversable.

Hemal Posted September 23, 2011 Share Posted September 23, 2011 Probably reverted to a viscous state, I doubt much can be done on them TBH without proper catalysed conditions and treatment - what did your friend use? Link to comment Share on other sites More sharing options...

From the smell i would say something like white spirit. And they are legitimate parts. Link to comment Share on other sites More sharing options...
JayeL Posted September 24, 2011 Share Posted September 24, 2011 Sounds like your friend has used acetone or an acetone based product, because acetone is a solvent for plastics I would suspect that the process is pretty irreversible. Try drying one on a warm radiator and see if that works, I doubt it will but can't think of anything else at the moment and unfortunately I'm off work for the next week or I would ask some of the chemistry geeks in work about it.

Azatoth Posted September 24, 2011 Share Posted September 24, 2011 It might reharden over time once the acetone like substance difuses from the material but that might take weeks. Link to comment Share on other sites More sharing options...

It will harden, it will just take a week or so, depending on how long they were soaking for. But the plastic may expand and look all 'blubbly', is the only way to describe it, but again that depends on how long they were being soaked for. /Ventris.

Brother Immolator Posted September 24, 2011 Author Share Posted September 24, 2011 Yes indeed some detailing right now on the pieces is 'chubby' lets say...Cant believe it my friend did chemical reactions to his marines. Lets hope they will harden over time so we can at least use them for battlefield casualty markers. Link to comment Share on other sites More sharing options...
No Foes Remain Posted September 24, 2011 Share Posted September 24, 2011 Yeah, you could always add some burn detailing so it looks like the armour has expanded due to extreme heat. Or something like that. I need to do something with my captain, hes been stinking out my sm bitz tub for a while. /Ventris, Link to comment Share on other sites More sharing options...
chromedog Posted September 26, 2011 Share Posted September 26, 2011 Depends on how much of the polymer was leached out by the solvent. (plastics consist of a polymer and a plasticiser - If too much of one is removed, they either go brittle or very spongey/rubbery.) I've had plastics stripped by acetone NEVER reharden (they just went into the bin). Link to comment Share on other sites More sharing options...

I've had plastics stripped by acetone NEVER reharden (they just went into the bin). The good news is that ill use some of them for as damage/dead chaos marines in my DA army bases. The bad news is that some of them were going to be used as conversion pieces that wont now EDIT:Some good news:They have rehardened a bit.However some details have been lost forever.

Brother Immolator Posted September 28, 2011 Author Share Posted September 28, 2011 Some news in case anyone is interested: Most of the pieces have reharden in place.So aside from an old type chainaxe the only two casualties were a bolter and a terminator powerfist which lost some detailing and has a smashed finger. A couple of shoulder pads look like they have truly been hit by bullets so all the more to make some dead chaos marines. Link to comment Share on other sites More sharing options...
