How long should it last?
One brand better than another?

I bought a kit (FastCap) about a year ago used it only a few times before it went kaput.
I kept it in an air conditioned room so it didn’t get hot.

Adam Savage from the Mythbusters has a new youtube channel where he goes thru some of his fun builds he is working on. Not necessarily woodworking, but you can learn a lot from that guy. Here he makes a rolling cart to hold some of his tools and has a great solution and some advice on CA glue storage.
Hope that helped. take care.

Store it in the fridge. It will last a lot longer that way. However, you will need to let it warm up a little before using as the cold increases the set time.

If it is the thin like water kind of CA glue, store it in a sealed bottle with some silica gel (google “silica gel” and you will find where to buy some. Its cheap.). The catalyst that sets off CA glue is moisture, usually in the wood. I keep mine in a large mayonnaise jar with the lid screwed on with a canister of silica gel inside. It is a large bottle of CA and it has been sitting on the bench for four or five years now.

Another trick. For the thin CA, get a hypodermic syringe and pull the needle off. Use a Dremel tool and cutoff disk to trim off the point. The back end of the needle is made so that it fits nice and snug onto the CA bottle (mine anyway). This will allow you to precisely apply small amounts of CA to your work. Yes, it will clog if it sits. Just hold a lit butane cigarette lighter flame beneath the needle for one second and it will open. Don’t breathe the fumes.

And one last hint. You can reuse silica gel if it becomes saturated with moisture. Just put it in your oven at a little more than 212 degrees for a while to drive the moisture out.

I keep my opened bottles in the refrig. Also, I wipe off the nozzle with acetone after using before I put the cap back on (no clogged tip or stuck on cap).

They have kept fine this way for at least over a year.

I’ve used the fridge as well. But Planeman40 is correct that moisture is what CA reacts with. A fridge is a moist place. So bottle must stay well sealed. I put mine in a zip lock, to provide another moisture barrier.

In the end, I’m not sure if it really is the coolness of the fridge (in general chemical reactions are slower the cooler), but it might be more that the temperature is held constant. In an un-airconditioned space, with daily heating and cooling, the thermal cycling might tend to force air in and out of a bottle that is not sealed perfectly.

I like Planeeman40’s idea of using a gel pack (desiccant) in a sealed bottle. I might give that a try.

Pops Knife Supplies has the best prices I’ve found, $5.00 for 1 oz bottle vs $5.00 or so for .4 os at the blusd and orange places.
Small operator but has a lot of knife making tools and supplies and adhesives. Good guy, met him at a local Hammerfest.
