Epoxy Question - am I doing something wrong?
Any help with this question will be appreciated. In regards to the last 5 minute epoxy I purchased, the product was fine except that after about a month, one bottle turned into a rock and was entirely unusable. I figured this was a bad batch or something so I purchased a different brand of 5 minute epoxy and after a month or so, the red bottle also turned into a rock. What is going on? Two bad batches in a row? When I use the epoxy, I keep the lids separate and I am very careful not to allow one part to come into contact with another part until I am ready to mix. Could this be the fumes causing this? Could the fumes from the CA cause this? Anybody have a clue?
Thanks!!
Thanks!!

No, I store the bottles in the basement, around 60 degrees F. The one bottle gets just rock hard.

I keep all my epoxy and ca indoors. The cold will make the epoxy very thick, reaction time when trying to mix them when cold is affected also. All my glue and solvents are in a tupper tote that is stored indoors until I use them, or until summer, whichever comes first

Do yourself a favor and don't bother with 5-minute Epoxy. I won't even look at it unless it's at leat 15-min, and I rarely even use that.
30-minute is your best bet. It gives you longer working time, adhears to the wood better, and even the 5-min stuff still takes 24 hrs to completely cure. If you really need the fast setting time, use CA - It's just as good as 5-minute epoxy.

RE: Epoxy Question - am I doing something wrong?
I talked to an epoxy expert once (works for an epoxy company in Bay City MI) and he said the bottom line is quality. He said all epoxy will go bad over time (usually it is the resin which will harden on it's own) but how fast it becomes junk is based on quality. I've had some problems with Tower Hobbies 30 minute and 5 minute going bad in a matter of a couple of short months. Careful when changing brands because a different label does not always mean a different product. Just my usual 2 cents.

Hi!
In my 30 years in this hobby I have never seen epoxy go bad.
but why use 5min epoxy when there is Ca glue...!?
I very seldom use 5 or 12min epoxy!

RE: Epoxy Question - am I doing something wrong?
Thanks for all the replies.....It sounds like maybe I just got two old batches in a row. One was from Tower and the other was Great Planes. Most likely the same brand.
I'll try the microwave thing and stand back and see what happens.[:-]
Thanks again!!

hi
if it is the double syringe type I think this happen often. I have had same problem. On the bottles I have use heat gun to heat the hardened bottles and this softens it up enough to use. haven't tries this with the double syringe type.
good luck and happy flying.
