How Does Super Glue Work?
Super glue is a popular adhesive that is commonly used in our daily lives for various purposes. From repairing broken toys and electronic devices to fixing home decor, super glue has become a go-to product for many. But have you ever wondered about the science behind the effectiveness of this glue? In this section, we will dive into the chemical and mechanical properties of super glue and explore how it actually works. By the end of this section, you will have a better understanding of the mechanism of action of super glue.
The Chemistry of Super Glue
When it comes to the chemistry of super glue, it’s essential to understand that it’s a type of cyanoacrylate adhesive. Cyanoacrylates are a family of strong, fast-acting adhesives that bond almost instantly with a variety of materials such as plastic, metal, wood, and ceramics. The most popular of these adhesives is, of course, super glue.
Super glue’s primary active ingredient is ethyl cyanoacrylate, which is a colorless liquid with a sharp and irritating smell. It acts as a monomer, meaning it’s a molecule that can bind chemically to other molecules to form a polymer. When you apply super glue to a surface, the ethyl cyanoacrylate molecules rapidly polymerize in the presence of moisture. This process forms long chains of molecules that create an extremely strong and tight bond between the two surfaces.
It’s worth noting that the polymerization process that occurs when super glue is applied is exothermic, meaning it releases heat. This heat generation is why you experience warmth when pressing your fingers together when they are covered in super glue.
It’s also vital to keep in mind that super glue is not suitable for all materials, and it may not work as well under certain conditions. For example, it doesn’t bond well to plastic due to its low surface energy. However, if you add a primer to the surface, it can help to increase surface energy and provide a stronger bond.

To summarize, super glue works by using a strong and fast-acting adhesive that creates an almost instant bond between surfaces. Its primary active ingredient, ethyl cyanoacrylate, forms long chains of molecules that create this bond, and the process releases heat. Although it’s not suitable for all materials, when used correctly, it is an effective and essential tool for bonding a variety of surfaces together.
The Mechanism of Action
Super glue, also known as cyanoacrylate, is a fast-acting adhesive that is commonly used in households and industries. It works by creating a strong bond between two surfaces by a process known as “anionic polymerization”.
When the liquid glue comes into contact with a surface, it reacts with the moisture in the air and on the surface, causing a chain of chemical reactions. This results in the formation of a strong polymer that bonds the two surfaces together. The reaction happens quickly and the glue dries almost instantly, making it a highly convenient adhesive.
The chain reaction begins with the dissociation of the cyanoacrylate molecule into anion and cation. The anion in the glue reacts with the moisture in the air to form hydroxide ions. These hydroxide ions then react with the cyanoacrylate cation to form a reactive intermediate called an “acyloxy anion”.
This acyloxy anion can undergo a second reaction with another cyanoacrylate molecule to form a longer chain polymer. This polymerization process releases heat and generates a large amount of energy. This thermal energy can be quite intense and cause smoke to emit from the glue.
It is important to note that the reaction of super glue with moisture in the air is what causes the smoke and not the glue itself. The glue simply acts as a catalyst for this reaction to occur.
External factors such as humidity, temperature, and surface area can affect the reaction and the amount of smoke produced. For example, a dry surface will result in less smoke when the glue is applied, compared to a damp surface.
Finally, it is important to exercise caution when using super glue as it can stick to the skin and cause irritation. In case of skin contact, it is recommended to wash the skin thoroughly with soap and water.
Super glue’s mechanism of action is a fascinating example of a chemical reaction that results in a strong bond between two surfaces. Understanding this process can help users apply the glue more effectively and safely at home or in the workplace.

Why Does Super Glue Smoke?
When you use super glue, you may observe smoke rising from the adhesive, leaving you bewildered. You may wonder whether this reaction is normal or something is wrong with the glue. In this section, we will explain the science behind the smoking of super glue, which can help you understand this reaction better and how to avoid it in the future. It is an interesting topic to explore, and there are also safety concerns to consider when using super glue. So, keep reading and learn everything there is to know about why super glue smokes.
The Chemical Reactions that Cause Smoking
When super glue is exposed to air, it triggers a chain of chemical reactions that lead to its solidification. Super glue, or cyanoacrylate, contains a chemical called cyanoacrylate monomer. This monomer works by reacting with the hydroxyl ions present in moisture in the surrounding environment. This reaction triggers a polymerization process which involves the formation of strong molecular bonds between the atoms of the surrounding materials and the super glue itself.
However, in some cases, the reaction may not be entirely smooth, and you may notice the glue smoking. There are different reasons why this might happen, such as:
- Excessive application of glue: Applying too much glue to a surface can cause it to smoke. This is because it prevents the glue from drying quickly, making the surface more susceptible to prolonged exposure to moisture, which triggers the air-polymerization process that causes the glue to smoke.
- Contamination: The presence of contaminants such as dust, dirt, or oils can interfere with the bonding process, leading to smoking. To avoid this, make sure to clean and prepare the surface before applying the glue.
- Presence of impurities: Sometimes, manufacturers may not purify the cyanoacrylate correctly, leading to the presence of by-products. These impurities can react with moisture in the air, causing the glue to smoke.
- Storage: Improper storage of the glue can lead to the buildup of fumes that can cause smoking. To prevent this, keep the glue in an airtight container, away from direct sunlight and heat sources.
While smoking super glue might be a cause for concern, it does not necessarily mean that the glue is unsafe to use. However, prolonged exposure to cyanoacrylate fumes can irritate the eyes and respiratory system. If you notice any irritation when using super glue, stop using it and seek medical attention immediately.

The Role of Humidity and Temperature
Humidity and temperature are two important factors that can affect the smoking of super glue. Generally, super glue smoking occurs due to exothermic reactions that take place when it comes into contact with moisture or water. The amount of smoke produced by the super glue can vary depending on the humidity and temperature in the environment.
Humidity:
| Relative humidity level | Smoke production |
| Less than 50% | Low |
| 50% to 70% | Moderate |
| Above 70% | High |
As the table shows, the relative humidity level plays an important role in how much smoke is produced by the super glue. When the environment is too dry with less than 50% relative humidity, the glue’s exothermic reaction is limited and produces very little smoke. However, when humidity rises above 70%, the reaction is stronger, and more smoke is produced.
Temperature:
The temperature also affects the smoking of super glue. The higher the temperature in the environment, the more likely the glue is to smoke. The following table shows how temperature affects super glue smoking:
| Temperature range | Smoke production |
| Below 40°F (4°C) | Minimal to none |
| 40°F to 60°F (4°C to 16°C) | Low to moderate |
| 60°F to 80°F (16°C to 27°C) | Moderate to high |
| Above 80°F (27°C) | High |
From the table, it is clear that the optimal temperature range for avoiding smoking super glue is between 40°F to 60°F or 4°C to 16°C. If you use super glue in a high-temperature environment, it will produce more smoke due to a stronger exothermic reaction.
Conclusion:
Humidity and temperature both play a crucial role in the smoking of super glue. If you want to avoid smoking, you should use super glue in a dry environment with a humidity level below 50% and a temperature between 40°F to 60°F or 4°C to 16°C. By following these tips, you can ensure a successful application without any unpleasant smoke or fumes.
