Superglue or Cyanoacrylate (CA) is a widely used Glue particularly useful for bonding Metal to Metal or Metal to Plastic. But what do you do if a mistake occurs? Either by gluing the wrong parts together or because of the rapid action of CA grab occurs before you've got your piece positioned correctly. For Large pieces sometimes a scalpel can be used to carefully separate the pieces by cutting the Bond. However for delicate Photo-Etch Pieces this is a non-starter. So here is how to do it without damaging the parts. For Metal to Metal Bonds use Acetone, readily available as Nail Varnish remover, but you can buy the real thing on EBay, there are also commercial debonders available but they are expensive and Acetone is much cheaper. Acetone will dissolve the Superglue completely, but it may take a while to penetrate under large areas, I use an Ultrasonic Bath which works in a few tens of seconds. Unfortunately for Metal to Plastic or Plastic to Plastic this is a non starter as the Acetone will also dissolve the Plastic. In these cases you need to take advantage of the fact that CA melts at around 75 Degrees Centigrade. So Boil the Kettle and let it cool a little and then in a container of this water at 80-90C immerse the parts and gently pull, nudge or prise and they will fall apart. Hot water from the Tap is not Hot enough as it is only 50-60C and remember you are only a few degrees above the melting point, so if you remove it from the Hot Water it will cool rapidly and the Glue will solidify again. For Skin use Acetone, but it does tend to evaporate very quickly on Warm Skin. So you can use a mix of Acetone and Vaseline, about 50:50.

Thanks Andy I did not know that - do you have a tip for unbonding CA in a skin to skin situation  J “Whenever you find yourself on the side of the majority, it is time to pause and reflect.”
