You are right. I looked it up on the Three Bond web site and it is OH
that cures it. I was going by what I remembered for Eastman 910 data
sheets about fifty years ago. And obviously I remembered wrong. Funny
though that you can put a drop on something and nothing happens until
you put something else against it and squeeze. I guess it is because
it has little surface area when it is a drop on a substrate. And when
you squeeze it with another piece, you spread it out so it can contact
the moisture on the surfaces of both pieces.

Sorry, it does cure in the presence of moisture; from Henkel-Loctite's MSDS
for cyanoacrylate glues:
Polymerized by contact with water, alcohols,
amines, alkalies.
Loctite thread locking agents such as 222, 241, 270 are anaerobic adhesives
however.
