Freezing CA adhesive 1/09

Hello Am wondering if anyone has an opinion about putting Cyanoacrylate Glue in the freezer to prolong it's shelf life , I have read some articles that say you must absolutely not get the stuff below 35 Deg. or so and only store it on the shelf or in the fridge., have also read other experts that say you should always store it in the freezer , most articles say that one must not return the CA to either the fridge. or freezer after it's been opened , condensation is what I understand is the problem , any thoughts would be appreciated.

Dunno the exact temp.

I think it helps.

Yes, you want to avoid condensation because water helps the CA to kick off. I think it is moisture from the air that causes CA to slowly thicken and eventually harden if you don't use it soon enough.

Both ideas affirmed here:

I have been keeping my CA in the fridge inside a freezer bag for years now. I do live in an area with low humidity. I also put opened bottles in the fridge in the same bag. Before I use glue that has been stored for awhile on anything of value I glue up some scrap wood. After it has been given time to set up I break it apart to make sure the joint is good. It should show wood at the break point. If it parts at the glue seam, it is time to replace the glue.

I routinely store it in a freezer at roughly 10 deg F. I store it in a sealed container inside a heavy duty zip lock freezer bag. I warm to room temp before opening the pint container to transfer to the dispensing bottles. The pint is recapped, placed back in the zip lock bag and goes back in the freezer. I see no evidence of any degradation at all under this kind of storage. I have stored as long as 18 months although usually three pints does not last me that long.

Good to know I am not the only one taking those steps.

Damn, you the man!

You must be a building fool, to use glue at that rate.

Or are you a crashing fool, to use it at that rate? ;-)

Where do you get your glue in pint quantities?

I've kept various types of CA in my basement refrig/freezer at 10deg F for about 12 years. I have 10 bottles in there now - a couple have been in there the whole 12 years. I've never had a bottle go bad.

I typically buy it in 2oz bottles and decant to 1/2oz for use. I keep the caps on the 2oz bottles but just leave the capillary tubes in the 1/2oz bottles open. When I want to use it, I remove from the freezer and warm in my hand so room humidity won't condense on it. If I expect to need it again in the next day or two I'll leave it out, otherwise I return it to the freezer.

If the capillary tubes on the 1/2oz bottles have a bit of CA on the tip when I put in the freezer, that bit will likely harden and need to be flicked off at next use. On rare occasion, I have to cut off the tip of the tube or remove the tube and soak in acetone.

I recommend NOT placing your CA in sealed bags in the freezer. The room air in the bag will contain much more evaporated water than the equivalent air in the freezer. When the bag cools, the amount of water vapor stays the same, of course, but the relative humidity rises way above that of the freezer air.
