My nickel--

When making epoxy and many other things, shelf-life is sometimes important and 
sometimes not. I had some two-part epoxy sticks that were over 20-years old 
and hard, and on a hunch heated them in the microwave for 15 seconds. They 
seemed as good as new, and performed extremely well, but I would not have bet 
my life on them.

It is in the interest of the manufacturer to give abbreviated shelf-lives for 
several reasons--

1) Corporate liability-tail reduction;
2) Requirement for certification--i.e. can you prove the shelf life is what 
you say it is?---You can't prove what you can't test;
3) Selling more product (not to be cynical...but there is some motivation 
there). 
4) Credit card requirements (most are unhappy with long guarantees because of 
potential charge-backs). 

Million$ could be made reselling out-of-date Loctite, epoxies, etc. Good for 
the environment as well.
