EA40 shelf life

[bentstick54]

I just bought some EA40 and have never used it before. Once I open it and then put the lids back on, what can I expect for its shelf life?
I have multiple sets of billets aging, and plan on z-splicing. Should I plan on doing multiple glue ups at the same time so the EA40 doesn’t go bad on me, or can I do them one at a time over a long period of time?

My last batch got gritty, and useless at the end of 3 years, I would use it up in two years if you  can. I bought mine in quarts in stead of pints not knowing shelf life at the time. Next time I buy it it will be in pints. Expensive stuff , but works great.

If you have concerns about shelf life with any glue, do a small test before committing to gluing up your bow components.

Things to look for, are if it takes significantly longer to cure, or doesn't fully cure.
The shelf life of epoxy is better than any other synthetic glue, but yes still have to be aware that one or both tins doesn't degrade.

Thanks guys.
Hamish. I was just concerned about after I opened the cans and them resealed them. It’s fairly expensive, so just trying to get the most out of it I can.
I could cut z-splices in for 1/2 pair of billets, then glue up all at one time, or do them 1 pair at at time depending on the shelf life of unmixed EA40
