Super glue gets hot when it dries due to an exothermic reaction that occurs as the glue's monomers bond together to form a polymer network. This chemical reaction releases heat energy as a byproduct, and the amount of heat produced depends on the size of the bonding area and the thickness of the layer of glue applied.
The heat-producing properties of super glue have potential practical applications, such as being used as a heating element in small electronic devices and in industrial or medical settings for bonding or sealing purposes.
Super glue, also known as cyanoacrylate adhesive, is a type of glue that is known for its strong bonding properties and fast-drying nature. It is often used for household and industrial applications, such as repairing broken ceramics, attaching metal parts, and sealing leaks.
However, one unusual property of super glue is that it can get hot when it dries. In this article, we will explore the reason behind this phenomenon and consider some of the practical applications of the heat-producing properties of super glue.
The reason for getting hot super glue
The reason why super glue gets hot when it dries is due to an exothermic reaction that occurs as the glue's monomers bond together to form a polymer network. An exothermic reaction is a chemical reaction that releases heat energy as a byproduct. In the case of super glue, the heat is produced as the monomers bond together to form the polymer network.
This reaction releases the energy stored in the monomers’ chemical bonds, which is converted into heat. The amount of heat produced depends on the size of the bonding area and the thickness of the layer of glue applied.
How does super glue work?
Super glue is made up of small, reactive molecules called monomers. When these monomers come into contact with a surface, they begin to bond together, forming a network of polymers. This bonding process is aided by the presence of water, which helps to activate the glue's monomers.
The reaction between the monomers and the water creates heat energy, which can cause the super glue to feel warm to the touch.
The heat-producing chemical reaction
The heat production that occurs when super glue dries is known as an exothermic reaction. An exothermic reaction is a chemical reaction that releases heat energy as a byproduct. In the case of super glue, the heat is produced as the monomers bond together to form the polymer network.
This reaction releases the energy stored in the monomers’ chemical bonds, which is converted into heat. The amount of heat produced depends on the size of the bonding area and the thickness of the layer of glue applied.
Factors that can affect the heat production of super glue
Several factors can affect the heat production of super glue. One factor is the type of material to which the glue is applied. Porous materials, such as wood or paper, absorb more water and produce more heat when the glue dries. Non-porous materials, such as metal or glass, do not absorb as much water and produce less heat.
The thickness of the layer of glue applied can also affect the amount of heat produced. A thicker layer of glue will produce more heat than a thin layer. The ambient temperature and humidity can also play a role in the heat production of super glue. In general, higher temperatures and humidity levels will result in more heat production.
Possible practical applications for the heat-producing properties of super glue
One potential use for the heat-producing properties of super glue is as a heating element in small electronic devices. The exothermic reaction of the glue could be harnessed to provide a small, consistent source of heat for applications such as warming hand warmers or activating chemical reactions in lab equipment.
Super glue's strong bonding properties and ability to produce heat make it a potentially useful tool in industrial or medical settings. It could be used to seal or bond materials together in a way that generates heat, such as in the repair of pipes or the sealing of wounds.
Precautions to take when using super glue
Taking certain precautions to minimize heat production and ensure safety when using super glue is important. To minimize heat production, it is recommended to apply a thin layer of glue and allow it to dry completely before applying additional layers.
It is also a good idea to avoid applying the glue to extremely porous materials or applying it in very thick layers. When handling super glue, it is important to follow the manufacturer's instructions and use caution to avoid skin irritation or eye contact. Using the glue in a well-ventilated area is also recommended to avoid inhaling the vapors.

Conclusion
In summary, super glue gets hot when it dries due to an exothermic reaction that occurs as the glue's monomers bond together to form a polymer network. The heat production of super glue can be affected by various factors, such as the type of material it is applied to, the thickness of the layer of glue, and the ambient temperature and humidity.
The heat-producing properties of super glue have potential practical applications, including use as a heating element in small electronic devices and in industrial or medical settings for bonding or sealing purposes.
However, to ensure safety, it is important to take precautions when using super glue, such as applying a thin layer and avoiding skin or eye contact.
