    Z-poxy not setting?

    For some reason my 30min Z-Poxy will not set. Im using it on my parkzone F4U which is made of Z foam. I reglued my landing gear a week ago (yup definitly more than 30 minutes) and after i took it up the other day i realized the LG were loose again. When i felt it, the epoxy was slimy and tacky. What im i doing wrong?
    Thanks for any help.

    RE: Z-poxy not setting?

    I suspect you didn't mix it up enough. Is that possible?

    RE: Z-poxy not setting?

    Kind of strange that you didn't determine that shortly after having used it??? Are you sure you added the hardener? Mix up a small batch just to check it.

    RE: Z-poxy not setting?

    It sure sounds like not mixing it properly according to directed mixing ratios of resin and hardener!.

    This is typical with epoxy resins, if they are not mixed according to directions with ratios of both bottles, they will never cure!. It wouldn't matter how long you try to dry it, it simply will not!!.
    I learned this the hard way and almost had one of the outer wing panels completely ruined, but i had managed to save it by peeling off the half wet fiberglass skin of the foam core panel.....
    I do believe in KISS (Keep it simple silly), but doesn\'\'t mean my models fall in this category!

    RE: Z-poxy not setting?

    Z-Poxy and some others eventually "go off"

    If you have used them over time, check where you used it and you will find that each use is a bit more rubbery than the one before it.

    I also had this happen, unfortunately it was a friends plane I was repairing.
    He brought it back a couple of days later and the epoxy was still as runny as when it was mixed, and yes, it was mixed and mixed well.
    Had to use alcohol to clean it all off and buy some fresh epoxy.

    I now always keep them in the fridge, along with all the other goos and glues.

    So don't be too quick to blame someone for making a mistake, the answer is not always the obvious one to you.
    It\'\'s the quality of life that counts, not the quantity.

    Thanks for the info everyone. I know i had eqaul ratios though. I probably didnt mix it very well. Im used to the spray on stuff. I'll go re glue.

    What is the lowest temperature which will allow Z-Poxy to cure?

    From the product sheet. http://supergluemsds.com/Docs/PT39%20%20-%20Z-poxy%2030%20Min%20System%20-%20PSS%20-%20Rev%202%20-%202013.pdf

    30 minutes at room temperature (77F or 25C) with full cure in 24 hours. Note For cooler
    temperatures, setting time may be longer. Product can also be heat cured at 200F for 35-
    45 minutes for full cure properties.

    Cooler temperatures will slow the curing process.

    Thank you. My garage is a bit cooler than recommended so I will need to wait a few months for things to warm up. I did get a small sample to cure using a heat gun but I don't want to risk messing up a full model.

    Bob,
    Last year I built a H-9 p-40 and reenforced the cowl with fiberglass cloth and epoxy. I had used some Hobby Poxy 45 min. epoxy ( remember that brand?) and it remained rather soft the next day to my surprise. Thinking I would have to redo it, I let it set in my Michigan basement workshop while I continued construction on the rest of the plane. Lo and behold after almost a month it was cured correctly. I discarded the rest and bought new epoxy. By the way, if epoxy begins to crystalize in the bottle, I find that a few seconds in the microwave clears it up.
    Hope this helps.
    Karl
