🔵 THE CHEMISTRY OF SUPERGLUE

🟢 Superglue is vital for quick repair jobs, but was discovered by accident twice lit owes its strong adhesive nature to the particular chemicals it's composed of. In this graphic we take a look at them and how they react to keep things solidly stuck together.

🔵 THE HISTORY OF SUPERGLUE

1942 Cyanoacrylates discovered during World War 2 Search for gun sight plastics Stick to everything, so discarded.

1952 Cyanoacrylates are rediscovered during research looking for polymers for jet canopies.

1958 Their potential finally realized, and the cyanoacrylates are developed into a glue which eventually becomes available commercially in 1958. Numerous other manufacturers follow suit.

🔵 THE CYANOACRYLATES

🟢 The most commonly used cyanoacrylate in superglue today is ethyl cyanoacrylate, but others such as methyl cyanoacrylate, can also be used. Medical grade cyanoacrylates such as 2 octyl cyanoacrylate can be used to close up wounds.

🔵 HOW SUPERGLUE WORKS

🟢 Cyanoacrylates cure in the presence of water. Only a small amount of water is required to kick off the reaction even the water vapor in the air is enough. The reaction produces an anion which can add to more of the original cyanoacrylate, a process that repeats to form the adhesive polymer chains.
