    I use super glue (loctite brand) quite often in my tying. I never leave the bottle open for lone being very careful to close it up real quick. Only use it maybe once per fly. Long before I even use 1/3 of a small bottle, it starts to get real thick and gooey. Is there anything I can use to thin the glue? I've written to LOCTITE but haven't received an answer. $4 a bottle is getting to be an expense. I usually get the small bottle with the brush.

    My bottle is doing the same.
    My main use for it is when tying on clouser eyes. I just continue to use it when it gets goopy and it still works fine.

    I primarily use gel type super glue so I have better control. However, I also use the liquid and have fairly good luck with Elmer's. As far as thinning goes, if you check with your local hobby shop, they probably sell something that will work. I seem to remember my brother sells a thinner from Zap at his hobby Shop.

    CA glue (cyanoacrylate...or super glue) has a shelf life.
    It lasts longer if kept cold. But that's difficult. Most wives would roast you alive if you tried to keep glue in the fridge.

    Most of it is manufactured in Japan and/or Taiwan. The Japanese stuff tends to be higher quality and clearer. The Taiwanese stuff tends to go bad sooner and it has a slightly more yellowish cast to it.

    Small bottles purchased at hardware stores have often spent a year or more sitting on distributor shelves, before they ever got to the hardware store.
    ZapCa and ZapAGap (can't remember the distributor) is made in Japan. It's among the better ones. They have high volume turnover, so you're less likely to buy old stuff if you get that or a similar high quality brand.

    Beware of "sales" on internet hobby store sites. Cheap glue means they bought a pallet of old glue that's going to go bad soon (thicken up).

    High quality glue (ZapAGap is not the only good quality glue) purchased at full price from a high volume hobby website is the best bet.....the most likely NOT to be old and near the end of its shelf life.

    ================
    I lost a bunch of money trying to distribute CA glue as a fly tying tool back in the late 1980s, as Sandy's Superfly. I did discover you can buy PTFE (Teflon) tubing online in various thicknesses. You can buy small amounts. #20 guage is good for ZapAGap. #28 guage is good for the thinner ZapCA. ZapCa is so thin it wicks into thread quickly, which is useful but dangerous. Too much glue will wick all the way up the wings and ruin the fly. ZapAGap is more generally useful. I maintain both. Use them both a lot.

    Cut a short length of tubing. Cut the top off the glue bottle. Shove the tubing all the way down to the bottom of the bottle. Make sure the bottom (inside the bottle) end of the tubing has a slanted cut on the end. Caulk the tubing in place with a hot melt glue gun. Now you have a "wash bottle" dispenser. Which means you do not have to tip the bottle to apply glue. You squeeze the bottle. You can watch the glue as it comes up the tube and reduce pressure just as it reaches the tip. That way you can dispense micro-dots of glue right where you want it. When you release pressure on the bottle any remaining glue in the tube gets sucked back into the bottle. If the tube does clog up it will be at the tip only. So use a razor blade to snip 1/16th of an inch off the top of the tube. Buy the smallest bottles available.

    So, is there anything that will thin the glue?

    ......not that I know of. But maybe I missed that part.

    There are instant hardeners. By the way. I forgot that subject earlier.

    You can unscrew the back end of an architects marking pen (choose a super light color). And then soak the fiber wick inside with CA hardener. Screw the back end of the marking pen back on. Now you can take the cap off the marking pen just long enough to wipe one side a proposed gluing surface with the marking pen (which puts a light film of solvent-based hardener on that surface).

    Now put some CA glue on the other surface and press the two pieces together. The glue will harden in two seconds or so.

    If you put CA in the fridge, first put it in something like a sealed glass jar.
    Over time a residue appears on the inside of the jar. So indeed, fumes
    escape from the CA tube or bottle.

    I haven't tried it but I'm told "Japan Thinner" (Ace Hardware) which to my knowledge is used to quicken the drying of shellac and varnishes, will thin CA...but I haven't tried it.

    I use a different Loctite glue called GO2 (not a super glue, works very well but takes just a little longer to dry), Stick n Seal Extreme Conditions (a contact adhesive gel that dries very fast and is very strong), and Liquid Fusion. When I want to use a super glue I buy the very small volume tubes at the dollar store for 4-5/$1.

    However, I do buy good CA glue from the Hobby Store when I'm out there.

    Thanks. I'm going to try and get an answere from Loctite. I like the glue and their little bottle with the brush. Not to sure about Japan Thinner. Next time I'm in the local ACE store I'll look at the can and see what is in it.

    Jack,

    It might take a little detective work but you should be able to find MSDS (Material Safety Data Sheet) for the specific LocTite product you are interested in. The solvent base should be listed.

    Now why didn't I think of that.
    Thanks. Will do some research tomorrow am.

    MSDS..........good idea. I just did that. They all look pretty much the same. It appears there is no solvent base. Super glue (if I read this correctly) consists of one material only: ethyl cyanoacrylate

    So somehow that must mean ethyl cyanoacrylate can be made to have different properties......or maybe....it's coming back to me now. They thicken this stuff by adding a clear and ultra-fine powder made from silica? I'm not sure about that. But I think so.

    All I could find is the mention of Acetone and we all know that Acetone is the " antidote" for unsticking super glue.
    Acetone is used to thin nail polish and also remove it. Wonder if it might work the same with the super glue??

    Super glue hardens by absorbing moisture from the air. Sealing out air is the key to keep it from hardening in the container.

    Refrigerators are the worst place to store tubes of CA glue. Warm air gets in the refrigerator and it cools lowering the dew point.

    The best is to put the tubes in a Zip Lock bag and put in packets of silica gel desiccant that come with shoes, electronics, and some medicines to absorb any moisture in the bag.
