Cyanoacrylate Adhesive is also called Cyanoacrylate Glue, or even more popular, Super Glue.
This adhesive is a simple polar linear molecule that polymerizes rapidly upon exposed to moisture, which is why it is called Super Glue.
For many people, this adhesive seems to be the most convenient glue available when doing various bonding jobs. Actually this is true, since Ethyl cyanoacrylate formulations are used for all types of general purpose bonding including wood, paper, and plastic materials.
Super glue is convenient because it is very fast-curing, extremely strong while needs no catalyst. You don’t need an oven or clamp to cure it as many epoxy adhesives.
Cyanoacrylate works like a pressure sensitive adhesive, and that is why a good fitting joint is necessary for strong bonds. You need a thickening agent why are the parts to be bonded do not mate.
>> How Does Cyanoacrylate Adhesive Cure?
To set the glue, you need moisture which naturally exists on the parts to be glued. Moisture is its catalyst.
Setting usually happens within 5 to 25 seconds, although sometimes it can take up to 1 minutes. Smooth surfaces with a close contact are perfect for a strong and fast bond with it.
>> What Types of Cyanoacrylate Glue Are Available?
The most common formulation of cyanoacrylate glues are ethyl formulations. They are usually available in 3 viscosities: thin, medium, and thick.
>> Advantages of Cyanoacrylate Adhesive
Cyanoacrylate glues are one part system, no catalyst needed. They have no solvent and can set rapidly in room temperature. They form good bond to many different materials and are available in different viscosities.
