Can CA expire or go bad?
I have some medium CA that I've tried to use on a coro wing with no luck. I've recently tried some test samples using various coro preparation techniques to bond them together with the same CA, with no luck. I've had the CA for about 2 1/2 years, but it has remained capped and appears to flow (viscosity) normally. Can CA go bad over time? I'll try to get a new bottle and re-test the bonding strips just to verify, but any additional information would be greatly appreciated.

Woodpecker and poly glue(mix in a few drops of water) works every time.( but takes a long time to cure)
With CA wood pecker, put dots of CA on one side mist water on the other side.
Very important: When You press the coro together You can't move it, not even a little bit or it will severely weaken the joint. Then it still need a few hours to cure to full strength.
I have no idea how long CA stays good in the bottle.

MrGreenSpeed is right! “Very important: When You press the coro together You can't move it, not even a little bit or it will severely weaken the joint. Then it still need a few hours to cure to full strength.” Just a slight movement will weaken your joint by almost 90%. And yes…CA glue has a very short shelf life, about 3 months depending on how warm the room temp is. You can prolong the life of CA glue by storing it in the refrigerator. An open bottle will keep for about 6 months and if it is not opened, it will keep for years in the frig. Another tip they told us, keep it out of the sun, they did not tell us why. If the opened bottle starts to become thicker, gooier or stringy…get rid of it. CA glue is cheap compared to what it could cost if something came apart or fell off in the air.
This info came from the manufacture.

RE: Can CA expire or go bad?
I figured I would toss this in here just for kicks. I have a bottle of thin CA that has a best by date of June 2002. It hasn't solidified yet, as I can still squeeze the bottle. However, it has been laying on its side for several days, (maybe even weeks) but all the glue is still in the bottom of the bottle.
