Re: Epoxy Failure, or...
I don't think it's the locust either. Mixing ratio error and or cold or both is my suspicion. The pumps can certainly get out of calibration--especially if the cold has allowed lumps of crystals to build up in there. Also, the greater viscosity of cold resin might just make it harder to physically mix it as thoroughly as possible.
This time of year we keep our glues and paints--all of them, not just epoxies--in the heated office instead of out in the cold shop. Our epoxy metering pump sits on a shelf right over the wall heater. We have a second Hot Box out in the back tent made from that building insulation foam with a simple lightbulb inside for a heater to keep the metering pump in when there's a big project out back. Warm and snuggly epoxy is happy, friendly, reliable epoxy.
Amphibious Macroplankton Oughtredia doublendus
Mostly found frequenting the littoral and estuarine zones in the southern half of the Salish Sea, though sightings have been recorded both north and south of this area, and occasionally, but rarely, inland, in freshwater environments. This species lives on micro-brewed beer and dutch-oven biscuits,and displays brightly colored nylon and gore-tex plumage during the rainy season. Approach with caution!
