Glue Storage Question
 

I do not use polyurethane glue or cyanoacrylate glues very often. When
they are new and I use them they are fine.
What I have a problem with is when I go to use them again at a later
date and they have gone hard. These glues are not cheap and I am
getting fed up with having to throw them away, buy new ones and start
the cycle over again.

What do you advise as a good way to store these so they retain theif
effectiveness?

Thanks for any and al help.

CA glue going bad? I haven't seen it yet, but usually wind up using up
the bottle before a year has gone by. I store mine at room temperature,
usually within arm's reach of the project area. Our humidity varies from
about 30% to 100% outside, usually 40-60% inside.

I believe both glue types mentioned are moisture cured types. I wonder
if storing the glue with a couple packages of dessicant nearby might help
any.

One thing to do is buy smaller containers. You'll use the glues faster
and have to buy it more often, but it'll be fresh. Another thing to do
for the CA at least is to advise everyone in your house where it is. At
least it will get used (if not lost first). The third idea that springs
to mind is to just think about using it more. You can even remove your
glasses, head to the closet, and announce, "This looks like a job for
Superglue!"

You can freezr CA-based glues and extend shelf life. Be sure to thaw
thoroughly before use.

I had an unopened poly glue go bad/expire on me so I haven't bought
any more. I understand that if you store it upside down after
opening, it remains usable longer. Only the top (now bottom) hardens,
where it remains exposed to air, evidently.

Every teeny tube of CA glue I've openeddied an early death, including
the gel type. I've never bought a large bottle of it but haven't
heard of them going bad. I'm sure more responders will have firsthand
knowledge of that.

In the last 10 years I have purchased 2, 1 oz bottles of "Super Glue" The
first bottle went bad after about 8 years and worked great up until that
point. The trick I use to preserve the shelf life of this type glue is to
keep the bottle in the refrigerator.

Polyurethane glue is much like shellac, it begins to cure in the bottle the
moment you open it. Don't buy polyurethane glue before you need it and
don't buy more than you plan to use on that project.

I think fridge works better.

I've had good luck storing CA glue in the refrigerator.
Polyurethane is catalyzed by hydroxyl (i.e. is water sensitive)
just like most silicone RTV adhesives, and should (I have only
tested with silicones) last longer if you seal the bottle inside
a (for instance) paint can with some dessicant. Maybe even
just a coffee can with a good lid...

By 'dessicant' I don't mean wimpy silica gel, use CaSO4 or CaCl.

I use small tubes of super glue gel to glue cue tips on cue sticks. I
store the opened and unopened tubes in plastic pill bottles with a
desiccant. I use the desiccants that sometimes come with the pills.

I have had unopened tubes of glue, sealed in an apparent air tight bag
that were all bad when opened. Have no idea how long they were in the
store.

I never had a tube go bad, even after opened, when sealed in an old pill
bottle with a desiccant. I'd guess about a year is as long as I had them
stored opened, and they remain good.

While on the subject, I might add that several months ago I glued a
6x48" sanding belt back together with some super glue gel, as a temp fix
until I could get some new belts.... damn thing is still holding up.

Glue Storage Question
 

We used to put it in the freezer.

I used to build 2 meter sail planes and used a fair amount.
Buying in bulk and then sharing with a buddy. I bought speed assist
by the 1/2 gallon. Glue by the pint. I could get a 55 gallon of it -
but that seemed life threatening!

I used to know a manufacturer in southern Ca. Once a major medical
supplier for Vietnam, relighted to service hobby world of users.

I had a small bottle in a tool box. I was the 'Engineer' in charge
of a machine the size of 6 large iceboxes - shipped on a dedicated
truck and the engineers, techs and I would see it installed. I got
to pay for fork lifts and union labor.... deal with the folks. Buy
and pay. The small tube was used once, but had been snapped close...

It came open on the trip back - and put a vapor of glue on the inside
of the tool box. It took years to get the glue out - as it broke down
in the oil of the tools it finally gave up.
