Anyone have unopened containers of CA adhesive turn all gummy? The CA is
not solid, just a very thick syrup. Is there a way to recover the CA so
it's usable (there were 3 unopened containers of it that I don't want to
throw out)? Like I said, the containers were unopened, as in NEVER
opened since the caps were screwed on at the factory. Probably spending
a good part of the summer in the shed, where it got over 100deg F
commonly didn't help matters.
It happens. Don't know of a recovery but you can get 2 tubes at Wal-Mart for
I think ca was invented for only 2 reasons. To glue your fingers together
and frustrate the crap of people building rockets.

California has a GUI now?
Should have known the command line was too much for those
soft liberals... ;)
The magic word is "volatiles".
Get a lot of that in the hobby... :)
Molecules that easily dissassociate from their matrix and migrate freely.
Solvents in products are generally volatiles.
A bit more complicated in CA because the stuff wants to combine with
The molecules drift out of the sealed bottle... a few at atime.
That would require reformulating the adhesive with the volatiles.
Expensive as hell if done right... flatly lethal if done wrong.
If the containers _can_ be be opened then volatiles will escape.
It's simply a matter of time, environment, and how tight the factory seal
Nope... it wouldn't help much at all.
Refrigeration, as pointed out elsewhere, has the opposite effect.
Not entirely certain I really want those volatile solvents escaping near
my food and medicine in my fridge, though :-/ Perhaps I'll buy smaller
bottles and just keep them in a cooler (on average) place, like the
closet where we keep other chemicals (cleaning products and such).
Hey... my insulin is alla time getting loose and wandering around the
fridge despite rubber seals and caps... if the level in the
bottlefalls below a few units... Family is still kicking :)
(Motto of a radicals chemist: "Molecules want to be free!")
If you like, but I think the escape rate of refrigerated CA would be
undetectable, especially in unopened (still full) bottles.
Say you keep your CA in the refrigerator & say you want take it to a
launch....say the nozzle too deformed or crudded-up for the top to go all the
way on & seal tightly.....in this situation, would keeping the bottle in ziploc
bag at the launch help any? -- Richard "say what?" Hickok
