The Chemical Reaction between Super Glue and Rubber


Super glue, also known as cyanoacrylate adhesive, possesses a remarkable ability to bond materials together, including rubber. When these two substances come into contact, a chemical reaction ensues, resulting in the hardening of the adhesive and the formation of an unyielding bond with the rubber surface.

At the heart of super glue lies cyanoacrylate, a powerful monomer that undergoes polymerization when exposed to moisture. Rubber surfaces typically contain moisture, acting as an activator for the glue and initiating the polymerization process of cyanoacrylate. This fascinating reaction involves the creation of long chains of molecules, yielding a robust and enduring union between the super glue and the rubber.

As polymerization occurs, heat is released as a byproduct. This heat can be problematic for certain rubber materials that lack heat resistance, causing them to melt or deform under the intense conditions. Thus, it becomes crucial to consider the heat resistance of the rubber before employing super glue in bonding applications.

Interestingly, the specific nature of the reaction between super glue and rubber varies depending on the type of rubber and the composition of the adhesive. Silicone rubber, for instance, possesses a low surface energy that makes it notoriously challenging to bond with any adhesive, including super glue. However, innovative advancements have led to specialized super glues tailored explicitly for bonding with silicone rubber.

It is important to note that while super glue can forge a formidable bond with rubber, it may not always be suitable for every rubber application. For scenarios that demand flexibility or elasticity, alternative adhesives formulated specifically for rubber are more appropriate.
