What is a cyanoacrylate (super glue) accelerator?

Superglue has strong bonding properties but still takes time to cure. Depending on the type of superglue you use, the curing time may be too long for you needs.

Hence the need for an accelerator which is almost immediate.

Super glue relies on moisture in the air to help it cure naturally. Whereas accelerators contain a certain amount of alcohol and water, this neutralises the acid within the superglue that would normally slow down the curing time, and gives an almost instantaneous bond.

Use your super glue as usual and then simply spray the accelerator on it to create an instant bond.
