Releasing cyanoacrylate from a thread

There?s this:

I can?t guarantee that foam eater won?t eat the shirt too, though.

Ingenuity.

That looks wonderful - even available from Toolstation! Will get some on my next order.

Emphasis on *some* A lot is Ethyl Acetate presumably because it is less harmful to the skin.

Freezer spray then, far less effective than heat. If you are expecting a chemical to be able to penetrate into a thread that is close to being totally filled with cyanoacrylate then you are, IMHO, in cloud cuckoo land.

If it's sized around M3 or M4, and a normal depth nut with not much additional metal around then 5 seconds with a soldering iron would release the bond with near 100% certainty.

OK - stick (!) it in a time machine and take it back to the time before it was stuck together

I'm sort of surprised that cyanoacrylate has stuck a thread so firmly together, it has no gap filling properties at all and really only sticks stuff well when the surfaces can be brought into *very* close contact. Like being part of the same object that has got broken. Has the OP actually tried to undo this thread using normal procedures like shock and tightening a tad before trying to loosen?

Some of the proper thread locking goops are very good but AFAIK they aren't based on cyanoacrylate.

wrong

finally correct.
