Any clues about making a cyanoacrylate-bonded nut easier to undo?
Heat from a soldering iron or blowlamp and if they fail use a dremel or an angle grinder.
I want a nondestructive method, preferably chemical. Heat is not an option.

Heat?
Acetone seems to be the thing. Not sure how easy it is to get, but it is a debinder and it should creep in there quite well.
(I know nothing except how to ask Wikipedia).
I got that from Wikipedia too :) I'll try it.
acetone (nail varnish remover). or nitromethane if you can get it. Only
2 things that work..soak if possible
fibre glass suppliers
Some Pound Shop superglue packs contain nine squillion mini-tubes of superglue and one tube of debonder. It might be a cheap way to get the small quantity you need.
No idea about the chemical it contains: the tube I have here says debonder on the front but just repeats the how to use superglue instructions on the reverse.

I thought Loctite used to do a product to do this?

some Nail varnish remover has acetone in it
Foam cleaner ? the stuff for removing uncured PU expanding foam (eg
Nail polish remover contains around 70% acetone (unless it's acetone free!)
I've always bought pure acetone from a chemist, numark branded i believe, couple of quid for a 250ml bottle,
you have to ask for it, and the chemist may ask what you want it for... so don't go in with a 2 foot long beard, the bed sheet wrapped around you and ask in a funny accent :)

Don't breathe the fumes!

Yes, but I'm not sure that works, ie it would evaporate befoer it penetrated down the thread far enough. Brian
that's why you need to be creative and build a more or less vapour tight enclosure in which the thing can soak for 24 hours
tube and modelling clay springs to mind.
"super Glue" solvent is available. (Intended for fingers etc stuck together.)
All very well, but how are you going to get it to seep down in between the space which is already filled with adhesive?
But what removes fully cured PU?
Have had some on a shirt which has been at the bottom of a pile for about five years now...
Enough of a smear to make it unwearable as is.
