I know lots of guys (probably) do this but I guess this could prove helpful to some people who find themselves waste pots of (not so cheap) epoxy at times because you couldn't use it up in time before it starts to cure-- especially after mixing fillers like silica making that window that much more smaller.

What I found was keeping the mixed pot as cold as possible made the epoxy stop from curing for as long as it stays cold.

So now when I'm epoxying parts-- I use 2 similar sized cups which are to be stacked on top of each other: 1 for the epoxy mixture, the other for putting a few ice cubes from your ice machine so that the 2 cups can be stacked on each other to keep the epoxy cold. Now I'm able to use the mixture up until the ice melts... Which is a while.

My question is... Can remaining epoxy be kept in the refrigator or the freezer to be used days or weeks later without compromising strength in any way?
