Does anyone know if Araldite Rapid, the stuff in two tubes, degrades overr time? I don’t mean once applied, I’m talking about whether it loses effectiveness while still in the tubes.
There’s nothing on the Araldite website to suggest ir does, although I did learn it’s not good for sticking Teflon… I did a quick iinternet search and managed to find this gem from 2009 on another forum, which was posted with no hint of irony. 
I went to use my trusty Araldite only to find that
the tops would not unscrew, and my attempts to
do it were twisting up the tubes themselves, with
a rupture likely.How long have I had it?
I don’t know, but the price, which is printed as part
of the box, and not as an add-on sticky label, is
given as, “6/-”So, then I turned to my “Rapid Araldite”, where the
price WAS on a sticky label as 86p (which is 2.8
times the price of the previous), and it is suffering from
the same twist-up-the-tube-and-not-unscrew-the-cap
problem.In both cases, I’d always been very careful to keep the
two tubes separate from each other, and not to mix
up the caps, with the two tubes stored opposite ways
into the box, so perhaps there is a sell-by date / shelf life
limitation for this product?
Sadly, the advice that followed didn’t help me. My problem isn’t unscrewing the caps, I’m just wondering whether to replace the tubes with new ones.
