How do I remove hardened epoxy safely?
How do I remove or dissolve hardened epoxy without damaging the contact areas?
Is there any epoxy thinner? I used 5min , 30 min epoxies in my plane and now I want to seperate some wooden parts safely. How do I do that? thanks :D 747 |

I've never been able to do it except to physically cut them apart

RE: How do I remove hardened epoxy safely?
There's really not much you can do except cut them apart. One of the reasons why epoxy is used on high stress critical areas is because of the tough a hold it does have. There is one thing you can try first, but I'm not making any promises as it usually doesn't work more often than it does. You can try heat to seperate the parts. Use a heat gun to heat the epoxy joining the parts. It will take time, so don't get in a hurry. If/when the epoxy starts to soften you can slowly work your parts apart.
If the heat doesn't work you're only other option is to cut them apart. Ken |

Epoxy is a polymer,
means it builds up long chains of molecules as it hardening, and then the bonds between the molecules are so strong that you cannot undo them. i would bet that there is no debonder for epoxy [&o]. sorry. Maybe to cut it out with a dremel and construct a new part. |

I had a plane lost in a corn field for over a month and some of the epoxy separated from the water logged balsa

i meant without screwing up the wood....

RE: How do I remove hardened epoxy safely?
Use your heat gun carefully. If you get it very hot, it will release the wood. I have done it to remove parts years ago and it works well. Its the only thing that will, even though the guys will tell you it won't. Give it a try.

HEY....What if I use this? Hobbico Hot Knife w/Solder Tip 25 Watt :
http://www3.towerhobbies.com/cgi-bin...&I=LXSD16&P=ML Will this cut thru the epoxy bonding between wood pieces to free the pieces? Will this also be a good soldering iron, its only 25w....For EP-RC whats the ideal solder watts needed...60w? |
RE: How do I remove hardened epoxy safely?
Jaso has a "Paint and Epoxy Remover" that turns epoxy back into goo. Then you have to mechanically scrape the epoxy residue off, repeat many times and finally acetone the daylights out of the wood to get it re-epoxyable. It's usually easier to grind and saw that go this route. Nasty stuff to use, too.

For soldering thick wires to metal plates - what kind of soldering iron do I use....?Is Higher wattage better ?
|
RE: How do I remove hardened epoxy safely?
The higher the wattage the better.
|
RE: How do I remove hardened epoxy safely?
Idealy for RC - electric........... Is it better if its more than 40w?
|
RE: How do I remove hardened epoxy safely?
properly applied heat from the heat gun will soften/remove epoxy with little trouble - done it many times.
