I may be the one misunderstanding the OP's request, but I thought he
was asking about 2 part epoxy - Paint - not laminating resin. If so
there isn't much that can be done about extending the shelf life once
the hardner has been opened. Maybe blow some argon from the TIG in
the can and do the same with a zip-lock bag around it for storage?

The last place to store it is in the fridge with food. (been there,
done that, and the fridge made the food taste strange for more than a
year) The stuff reacts with moisture and the innards of a fridge is a
very moist place.

Leon,

You may be the only one who caught the "spraying" part of the original
post. Yes, I believe he was referring to two-part epoxy paint and
everyone was answering for two-part epoxy adheasive and resins. I
don't know of any way to extend the shelf life of two-part epoxy
paints but would like to hear some good answers.

The temperature thing will work - to a point.

I've put mixed RandoPlate and EpiBond in the friges after mixing so
it wouldn't be sitting around cooking while I was spraying.

I was using a small touch up gun to spray my Tailwind fuselage truss.

When the gun goes empty, pop it open and pour in another load.


Slow it down, yes. Maybe even over night.

But this won't _stop_ the reaction.

Actually, I have saved small amounts of 2-part PPG epoxy primer by
putting it in the freezer. The stuff appears to be usable for a week or
2. It stays liquid and sets up after spraying.

I usually mix it by the partial-teaspoon to do touchup with an airbrush.
