Things to Know About Cyanoacrylate

Cyanoacrylate, such as FS 4000, is a type of adhesive that is an acrylic monomer that turns into plastic once it has cured.  There are many different family types for cyanoacrylate, including industrial, household, and medical, but they are all fast-acting and strong.  When a person uses this adhesive, they are starting with a liquid that then turns into a long chain that is solid and sturdy.

It is necessary to apply a thin layer of this adhesive, as that is the only way that the reaction of the liquid and the air will quickly produce a strong bond.  Thicker coats will not dry as fast, creating movement and a bond that is less than desirable.

One of the most common forms of cyanoacrylate is ethyl 2-cyanoacrylate or ECA, and many people refer to it as Super Glue or Krazy Glue.  Other types are methyl 2-cyanoacrylate, n-butyl cyanoacrylate, and 2-octyl cyanoacrylate, with the latter used mostly in the medical and veterinary fields.
