In my experience, superglue sets instantly, usually before
you've got the workpieces together straight, why on earth would
you need to accelerate it?

There are two types. One sets on exposure to air (moisture
actually), and the other requires an activator to set.


There's also the rubbishy superglue I have had from the pound shop
which doesn't set even if left for hours.

(Not to be confused with the watery variant they sell which squirts
everywhere when opened and sets immediately.)

I thought cyanoacrylate was a chemical which would be the same in every
bottle?

Nope, that name is a class of adhesives, just like epoxy is too.

Is it watered down with something else?

Nope.
