Actually, that's the WORST thing you can do with superglue type adhesive!! There's nothing to be gained by putting glue into a cold environment. It's AIR, or OXYGEN that cures all glues unless you need an activator which is NOT the same as an accelerator! The smaller the space, the less the air. In this case if you're putting glue into a refrigerator this cools the air, but doesn't stop the air from drying it out, only it prolongs the glue as the air inside the refrigerator is not moving as much, and the oxygen in it doesn't build, or last as long because of such a limited space which is designed to push all the air out when you close the door which helps to retard spoilage.
All you're doing is making the glue thicker as all things become thicker in a cold environment. This does nothing to improve the quality of it, but when you have more air, especially if the bottle isn't sealed properly, or is about a third of the way empty, or half or more the air inside the bottle slowly cures whatever is inside. You can add acetone to thin it IF you get to it before it becomes too thick to save. The problem is that the cyanide in it evaporates from the glue mixture as it dries as this isn't what it's made from, but rather it's a catalyst that forces the acrylic in it to harden faster when applied to either warm, or hot surfaces, and bond to porous materials which is why it bonds to skin so well. If your glue is drying out you're not using it frequently which I do.
I buy the Bob Smith Industries 2 Oz. purple bottle medium thin as this is thick enough to control, and close small gaps, but doesn't run like the thin (regular) super glue, and isn't too thick like the gel. Any type of glue will be ruined inside the bottle just like enamel paints which dry when you have more air than paint inside the jar. The lid no matter how tight won't stop this from happening, it only slows it down. These Bob Smith Industries bottles are made from NYLON which is probably why your parts aren't gelling together. These bottles are designed so that the glue DOESN'T stick to it easily!
Use POLYSTYRENE to wrap around things instead of nylon thread. I have sprue that I stretched for making antennas, and radio wires for models. I glue it by running a thin bead all the way down the part, then I wrap the newly made polystyrene reinforcement wire over it slowly, then I hold it in place to let it dry for a minute. I don't have this problem with adhesion. I wondered with some of this stuff, but it's more a matter of patience than the glue. If you have a bottle of glue sitting around for a year, and it dries up, or other problem that's probably why you're having trouble with it!
