Almost all (All I've ever tried, even) epoxies will set underwater.
Once you mix the epoxy and the amine (the "hardener") together, in
the proper ratio, it will cure. In vacuum, underwater, in any
solvent that doesn't attack it, below freezing, whatever.
(Temperature will change set time, but even at really low
temperatures, they'll cure, eventually.) That's one of the things
that makes epoxies so nice, they're hard to screw up.
Getting it to stick to a wet surface is a different problem, of
course. Adhesion to whatever it is you're trying to stick it to is
one of the few common failure modes. Good surface prep -- sanding,
filing, grinding, cleaning with a solvent, helps quite a bit.
The other common problems with epoxies are not mixing correctly, and
not using enough in the bonding area. Follow the instructions;
adding more hardener will not make it set faster. If you need
a different set speed, use a different product. (I have a really
hard time squeezing the same amount of stuff out of two little tubes,
which is why I'm a fan of epoxies that come in a dual syringe type
package, or as putties.) When using an epoxy as an adhesive to glue
two pieces together, don't clamp so hard that all the epoxy is forced
out of the joint.
