Question/ Note about old epoxy

nute said:

So just a little bit ago, I was getting ready to glue a switch band on, and then do some fillets with my Rocketpoxy. It's old, from Wildman's black saturday sale, so right about 10 months, but notthat old,right? Anyway, as I was opening it, I realized it was almost empty, and just as I realized that, maybe 1/3 or 1/4 second after opening it, there was an incredibly powerful, almost but not quite burning sensation in my right nostril. It felt almost cold, numb maybe, a bit painful. As if I had just inhaled a wiff of something really nasty. Does anyone know what that could have been? I'm not exactly excited to finish up my Eagle Claw now, as I don't want to risk inhaling anymore of whatever that was. I seem to be fine now. I immediately dropped the epoxy container, and ran outside for some air. Does Rocketpoxy have a shelf life, and have I reached it? I'm fairly interested in chemistry, so if anyone can explain what was going on in that epoxy container, I'd appreciate it.

There was a thread on here not long ago about some older epoxy taking on an ammonia smell. I don't remember what brand was being discussed but you might want to search for that?

I used some old RocketPoxy about a month back on my Madcow 4" V2. Yes, hardener is moving from tan to caramel color and fairly rank. Seems to also be some shrinkage and is more stiff. Still mixed and cured fine.

So, a bit of thread from the dead here. I opened up my original pint set of Rocketpoxy today. Part A (the white stuff) was still white, although a bit stiffer than I remembered, and no evil odor emanating from within (not , at least that this old nose could smell)....
Opened up part B and burned all the nose hairs out of both sides of my nostrils. Smelled worse than a week old bag of cat pee (don't ask how I know that smell... :no: :no: ). Very strong ammonia, there was... The color was very close to caramel and the consistency was peanut butterish. After the top had been off for a minute, the ammonia smell was gone and it smelled like it used to (not unpleasant, a bit sweetish). So, I mixed up a batch. It will definitely be good for fillets now as the mix was quite stiff, but malleable. So, after it cures, I'll report back as to how it went. Keep in mind this was some of the very first pints Wildman sold, so it has some good age on it.

I've had Rocketpoxy and Aeropoxy a few years old at the bottom of the cans,,
lids don't seal well anymore,, lumpy,, chunky,,
mix really well,, whip it up smooth,, and works fine.....
