Officially?  Or Unofficially? 

Circa Mid 1980s, Loctite both changed it's part numbers, and put a shelf life on all their products.  It was explained to me by the local loctite rep that the change had everything to do with the new Mil-specs that were coming through at that time (WS-6536 if I remember right).  That spec required all chemicals to have a shelf life, so loctite put one on their products.

That said the rep also said "if it looks good, it IS good" - I still have a BIG bottle of blue loctite that had to be replaced because it was the "dateless" kind - still works fine

BTW for those of you who say "Loctite cures due to lack of oxygen" - that's partly right It won't cure unless there is no oxygen, but it also needs a certain amount of ions (don't remember if it's + or -) anyway, that is what the loctite primer is for - if you are working with passivated stainless, please use the primer, or it won't cure
