Shelf life of 2k hardener

[jordan1]

Does hardener deteriorate once opened, I have just used some that I opened around a year ago, just seems to be taking a while to 'go off', ambient temperature ok.

It starts to crystallise before going solid so you can tell if it's ok

Yes, I thought it would be ok until it starts to crystallize, but this looks fine, can't see any date on tin.

I bought some to do a job that got delayed a year or two. When I opened the tins, they were solid. I didn't realise that it went off so fast!
