Old Epoxy lifespan?

#1

Hello-
I have some Resin Services epoxy and tooling surface coat, never opened, from about 7 years ago sitting in my closet. It’s always been there indoors in a 70F or so environment.

What are the odds this would be any good to use after this much time?

And…if it’s no good, how do I get rid of it? Hopefully it would react enough to turn solid so I could throw it away.

i would test to see if its still good, and if it works i’d use it for non important projects.

As long as it was in a closed container it is still good. If it catches some humidity the pot life will be shorter but structural it will still be fine.
