Chemical Structure of Cyanoacrylate
Cyanoacrylate is a family of strong, fast-acting adhesives that are commonly used for bonding various surfaces, including plastics, metals, and woods. The chemical structure of cyanoacrylate is relatively simple, yet crucial to understanding how it works.
- Cyanoacrylate is an acrylic resin that belongs to the ester family because it contains the ester functional group (-COO-).
- The main component of cyanoacrylate is a small molecule called ethyl cyanoacrylate (ECA), which consists of a cyano group (-CN) attached to an ester group (-COO-) and an ethyl group (-CH2CH3).
- The cyano group is what gives cyanoacrylate its adhesive properties by reacting with moisture in the air to form strong bonds.
The reaction between cyanoacrylate and moisture is exothermic, meaning it releases heat. This is why cyanoacrylate adhesives form bonds so quickly – in just a matter of seconds.
The chemical structure of cyanoacrylate is shown in the table below:
| Functional group | Chemical formula |
|---|---|
| Ester | -COO- |
| Cyano | -CN |
| Alkyl | -CH2CH3 |
Overall, the chemical structure of cyanoacrylate is what makes it such a powerful adhesive. Its ability to react with moisture in the air and form strong bonds quickly has many practical applications in industry and everyday life.
Differences between Ethyl Cyanoacrylate and Cyanoacrylate
Ethyl cyanoacrylate and cyanoacrylate are two types of adhesives that are commonly used for various purposes. Though they are related, they differ in several ways.
