Does epoxy glue have a shelf life?

[Deplorable Me]

Most glues I've used over the years have a shelf life. Last week opened some Devcon epoxy glue purchased in 1987. It mixed, set and is holding fine.

Good stuff to have in the home prepper stash.

This batch is labeled 2 ton.

Its probably because the unmixed components on their own are inert?

Things I've fixed years ago are still holding. First time I've mixed up virgin components this old.

I always write the DATE OF PURCHASE on Glues, Tapes, Chemicals.

I've found Elmer's Glue, and Glue Sticks, are no good after a couple of years.

Turpentine, Acetone, Alcohol, and the like will be good for Centuries.

Surprised it went that long. I would have said it was years but I had some 2 part epoxy that I think poured slower after several years. If you can get it to mix and it sets in the normal time frame I'm sure it's plenty strong.

JP Weld lasts a long time, 5 years at least. Elmer's carpenters glue has gone bad on me rather quickly, don't know if it got "black mold" but it looked that way. Mix compounds seem to last quite a long time.
Super glues and the like seem to dry up as soon as they are opened.

Same with the ones like gorilla glue which mix with a bit of sprayed on water on the surface. Nice glues but if you don't use them a lot you end up with just a block.

2 part epoxy is the real deal. I have not been without it for a long time. I absolutely love the stuff.

In my experience epoxy is like a women. If you leave them alone they both tend to break down and not be able to hold things together. J/K they both hold on for long times.

My experience may be unique, but the JB Weld I've used was very dry, mixed poorly, and was thoroughly unsuccessful in adhering anything together.

And I had just purchased it to use in an immediate project.

(I probably should have complained to the manufacturer then and there, but did not. Too late now.)

I mainly use 5 or 30 minute stuff I got from a hobby shop. I have used 5 minute devron and unlike the 5 minute hobby shop, it truly has a working time of only 5 min. Mixes very hot and starts to set up aggressively at 5 min. I built some furniture with it last time because I didn't have the time to wait 24 hours for the proper wood glue to dry.
