Moisture: How Does Moisture Degrade Super Glue?

Super glue, also known as cyanoacrylate adhesive, is a go-to option for quick and strong bonding in various applications. However, moisture can be its nemesis, compromising the integrity of the bond. In this article, we will explore how moisture degrades super glue and discuss preventive measures to ensure long-lasting adhesion.

When moisture comes into contact with super glue, it triggers a chemical reaction that causes the glue to cure and harden. This process creates a strong bond between the surfaces being glued together. However, excessive moisture interferes with the curing process, preventing the glue from fully hardening. Water molecules can disrupt the chemical reaction between the cyanoacrylate monomers, weakening the bond or preventing it from setting entirely.

Excessive moisture compromises the strength and durability of the bond created by super glue. The water molecules can penetrate the adhesive, causing it to swell, expand, and develop cracks over time. As the adhesive swells and contracts due to changes in moisture levels, it becomes more prone to breaking. This gradual degradation can render the bond brittle and less reliable.

To prevent moisture from degrading super glue, it is important to store it in a dry environment and keep it tightly sealed when not in use. If working in a humid environment, consider using a dehumidifier or applying the glue in a controlled environment to minimize moisture interference during bonding.

If a super glue bond is exposed to water or high humidity after curing, dry the area thoroughly and consider reapplying or reinforcing the bond if necessary.
