: I suspect that you're correct. Commercial manufacturers that make
: laminated products using epoxy typically "post-cure"
: them at temps over 100 degrees, which increases the strength of
: the epoxy considerably. Given that, it makes sense that lower
: temps would produce lower strength. It can also dramatically
: increase curing times, pushing them out to weeks or even months
: for a full cure.

It's a different resin/hardener that the post cure at those temps but you're correct that with the proper resin elevated post cure temps increase the strength properties of those resins. I was just surprised that at 50 degrees the joints failed after a week's cure. Fixed them this week with 5 minute epoxy, cool stuff but pricy.
