No it does not cure in air.

Superglue is an anerobic adhesive and cures when air is removed by
fitting the two parts together.


Bob, it's always puzzled me why it doesn't set in the tube / bottle as
they are sealed from the air

Hi Andrew, my understanding is that there is always some air in the
bottle. You may have noticed that sometimes it does go off in the cap
thread but the adhesion to the polythene type tubes is poor and the cap
can still be removed.

Oh dear.

You are even more wrong than I supposed
