I am still using Araldite 420 that is 10 years old and still as good as new. It has been open all this time, but with a lid on of course. The Araldite itself crystallized once or twice, but yu simply stand the can in very hot water for a while and give it a good stir. The hardener never changed its state.This question seems to come up regularly every few months.

Picking up on the deterioration of the hardner - do you have data on that?
How many months?

Does anybody have a realistic idea how long unopened 420 is good for?
Stored at over 70f

Will

My Aeroepoxy is over 10 years old. The opened can of hardener does
change color, to wine red, and eventually to a blackish red. It is a
bit disturbing to see this color on laminations, but the strength
appears to be good as new. The sealed cans (which also sat for 10
years) also show a slight red coloration, but not nearly as much. I
think a vacuum sealing method for storing these epoxies would be a
useful addition.

I saved opening the araldite 420 until bonding the cockpit module, and
for all other jobs I've been using the 50ml version of epibond 420.
