Keep them in the fridge.

I've done this with proseal and it still works two years after the
expiration date.

Keep them well-sealed, especially in the fridge, presuming
that you also keep food in the fridge.

I'm not aware of a specific airborne contamination issue
with epoxy chemicals and food, but, as I recall from my
days as a lab tech, some chemicals kept in a refrigerator
will contaminate some foods that way.

More likely this is an issue with volotile sovents, but
why take a chance? Sealing the containers well is
sure to minimize oxidation and condensation also.
