What is the weakness of superglue?
Impact resistance is generally poor, because of the thin, inflexible bond. This is especially true with two rigid substrates such as metals. The methyl cyanoacrylate bond melts at approximately 165°C. Prolonged exposure to temperatures in this range results in a gradual but permanent breakdown of the bond.
What can weaken super glue?
Blot the glue with acetone or rubbing alcohol and let this substance break down the glue. Clear away with a damp cloth. For fabric: Use acetone, but test sparingly first to avoid potential damage.
What destroys super glue?
