A question for anyone who has used a 5-minute epoxy. What do you use to release the stuff? Thanks.

Hey Otter, depending on how long its been set, you might be able to soften it with Lacquer Thinner. Either that, or Jasco Paint Stripper(and epoxy remover), but that stuff is pretty nasty.

No doubt there is a commercial product for this, but in a pinch, warm water and a bit of time will do the trick.

When you say release it, do you mean a type of mold release? If that is the case, any carnuba wax will do. Auto polish works well for me. As far as I know, acetone will not release epoxy. The five minute has a lot of fillers and is weaker than 2 ton, or pool epoxy, so acetone might weaken the bond. In most cases with epoxy mechanical removal is recquired. I do a lot of mold work with epoxy and I have had quite a few total disasters molding fine stuff. In making either a male or female mold, epoxy is used with silane roving. Then acetone is used to remove contaminants before laminating. When the mold is ready, carnuba wax is used as a mold release. The shineyer the finish, the easier it is to release. If you got epoxy on something, it is dig away time. For small parts I have molded, I have waxed, and built a well out of petroleum jelly.

I have found that 5 minute epoxy (often used for applying caps for artifitial nails) becomes very brittle when soaked for a while in water. (used to do nails for a living) Gets kind of "crusty" and you can flake it off stone with something metal and it won't scatch the stone. I'm using epoxy 330 right now for my jewery (will cure in 5 mins. with a heat lamp, but usually takes longer) and when I boo-boo I can usually get it off that way.

Thanks all for the replies. I will pass the info on to my hubby. The instructions that came with his lap-lap said to use 5-minute epoxy for dop transfer. So he needed to know how to release it without scratching the stone. Guess I should have said all this when I first posted. See what happens when your brain goes on vacation a day before the rest of your body does!
Thanks! Otter

Oh, changing dops. A candle will do the job very nicely. The heat will not damage the stone, you do not burn the epoxy, you soften it. If it is a stone transfer. heat the dop you are removing rather than the stone. Doing that is as exotic as lighting a candle. I use an alcohol lamp. It is a squareish glass bulb with flats all over the resivoir, same as a candle only no wax.
