"Another important trait is that cyanoacrylate sets up fast, often in less than a minute. A normal bond reaches full strength in two hours, and is waterproof. There are also accelerants that can force a set-up as fast as two or three seconds, at some loss of strength.
Acetone, which is found in nail polish remover, is a commonly available solvent capable of softening cured super glue.
Cold temperatures cause cyanoacrylate to become brittle. Cyanoacrylate's bond can be weakened, allowing disassembly, by
placing a glued object in a household freezer for several hours." announce1
