I mixed up some epoxy this evening using my cordless drill and a makeshift stirring dowl. Normally, I have 30 minutes or so to work with the epoxy before it starts to get sticky. But tonight it got wicked hot (like almost ready to melt the plastic mixing container) and started to get stringy really quick. It hardened in about 15 minutes to the point where I couldn't even pour it out of the container.
Anyone know why this is? I mixed it quite vigorously with the drill. Also, it was pretty warm out this evening, say 80 degrees or so. I believe my proportions were good, but its hard to tell with the pump system.
