- Acetone: used as a stabilizer and works to slow down the hardening process of the glue.
- BHT (butylated hydroxytoluene): works as an antioxidant and is added to prevent premature hardening of the glue.
- Poly (methyl methacrylate): also known as PMMA, is a thermoplastic resin that makes the glue more resistant to impact and shock.
- Hydroquinone: is added to prevent the glue from hardening in the bottle and is typically found in small quantities.
When these ingredients are combined, they form a powerful adhesive that can bond almost any surface in mere seconds. However, it is important to note that super glue should be used with caution as it can be dangerous if not handled properly.
How Does Super Glue Work?
Have you ever wondered how super glue can instantly bond objects together with just a few drops? The answer lies in the unique chemical properties of this adhesive. Super glue, also known as cyanoacrylate adhesive, is a popular bonding agent that has been used for decades in various industries. In this section, we will delve into the mechanics of how super glue works and the chemical reactions that lead to its high-strength bonding properties. So, without further ado, let’s uncover the science behind super glue.
Chemical Reactions of Super Glue
Super glue, also known as cyanoacrylate adhesive, is a fast-drying, strong adhesive that bonds almost instantly when it comes into contact with moisture. The bonding process involves a chemical reaction called anionic polymerization. Let’s take a closer look at the chemical reactions that occur when using super glue.
| **Chemical Reaction** | **Description** |
| — | — |
| Anionic polymerization | When super glue comes into contact with moisture, the chemical makeup of the glue changes, and the adhesive bonds with the surface it’s applied to. The process starts with a nucleophile attacking the electrophilic carbon of the cyanoacrylate molecule. This initiates a chain reaction, where successive molecules add to the growing chain, creating a polymer.|
| Exothermic reaction | The anionic polymerization process releases heat energy as a byproduct, creating an exothermic reaction. This reaction speeds up the bonding process and is what allows the glue to dry quickly. It’s important to note that the heat generated can cause burns or damage to surfaces, so it’s essential to use the glue in a well-ventilated area and with caution. |
| Hydrolysis | When super glue is exposed to water, the polar bonds in the glue are disrupted, resulting in hydrolysis. The reaction causes the glue to break down and lose its adhesive properties. Additionally, the presence of water on surfaces can prevent the glue from bonding properly in the first place.|
The chemical reactions of super glue involve anionic polymerization, an exothermic reaction, and hydrolysis. These reactions are the foundation for the fast-drying, strong adhesive properties of super glue, but they also require careful handling to avoid any mishaps or accidents.
