I need a small amount of epoxy glue every 3-6 months. The problem is
the last one I bought usually drys out by the time I need it again
So, I have to buy the tubes again when I need it. Is there any way to
buy this stuff that I can reuse it for a year or so?
I use PC-70 which I buy in two 4-oz cans, made like paint cans with
lips and all that, and I've never hard it go bad. Some times it takes
a couple years to use it up, but I think it's gone 5 years.
It's getting hard to find that size, for some stupid reason, so I
bought the 4x1 inch cardboard tube, and that lasted fine too.
There is also PC-11 which is white instead of grey. PC-70 is
fantastic, sticks to almost anything including glass, malleable before
it hardens, can tolerate temperatures at least 200 degrees, waterproof
and better than that can be applied to a leaking pipe while it's
dripping and it will still harden waterproof (I had to keep pushing
the stuff up to the pipe for a few minutes iuntil it got hard.) PC
11 is probably just as good.
So I'm wondering if you let any of part A touch B. I use separate
screwdrivers or popsicle sticks to spoon out the glue, and I use one
of them to mix the stuff, and never bring it anywhere near the cans
after that. It takes 50-50 to get the best mix, but I think even a
tiny bit could ruin the whole other can.
I also buy epoxy glues in a double syringe. I squeeze the stuff out
and put the cap back on before i start to mix the two. I've had a
couple tubes go bad, but it's rare, and the other times it can take
years before I finish a whole syringe worth. I've used the 60 minute
glue, the 5 minute glue, and I tried the 1 minute iirc glue. I
haven't checked if the last one is still good, but I expect it is.
I used to use toothpaste style tubes. The syrringe is probably more
expensive but I'm usually saving lots of money when I glue something,
a few more pennies on glue is well worth it
What brands have you been using?
Epoxy does not dry out. You must be mistaking it for a glue which
contains solvent. Epoxies come in 2 parts which consist of epoxy and
hardener. Easiest to use is the syringe type that meters out exact
amounts of components and when sealed properly will last for years.
Just wanted to add my favorite 5 min epoxy to the conversation.
Fastweld 10 made by Ciba, seems to be relabeled with other brand names, but
called Fastweld 10. My first 9oz tubes lastd over 15 years.
I purchased my second set of tubes about 3 years ago.

This may or may not be the best price, just google Fastweld 10.
I'm careful about not switching caps on the tubes, but I also keep all
my epoxies in the kitchen freezer until I need to use them. I've got
some (not cheap) electrically conductive epoxy in our freezer which has
to be at least 15 years old which still works great when needed.
I keep film, batteries, medicine, candles, and some glues in the
I have a new camera and I'm also keeping my digits in the fridge.
Each one is small but there are billions of them.
I'm looking for another fridge to keep my food in.
