I've worked with epoxies for years in my day job (aerospace). Usually you can get full cure by either extending the cure time or upping the cure temp but not necessarily both at the same time. Most of what I deal with is driven by engineering specifications but within those specifications there is usually a preferred cure and and an alternate cure. One is usually at room temp (won't apply here obviously) and takes quite awhile and then there is an accelerated cure which calls for some temp above ambient and a much shorter time.

I said all this to make the point that within certain parameters there is more than one way to get the same result. One of the axioms in my business is that it's hard to over cure at a given temp but an under cure will get you killed....
