Hiya Andy,
No, it is the new Ciba humidity-resistant stuff for 500s. 3D's data
sheet shows a Tg of 68C with a UV post cure and 88C if thermal cured for
2 hours at 80C.
It seems to me that one would have to "sneak-up" on the 80C number if
the initial Tg is only 68C. If not, wouldn't you have a blob in the
oven?
I'm looking for a recipe like "65C for 30 min, 70C for 30 min, 80C for 2
hours" or something like that. Also, some failure modes to expect
(e.g., distortion, dimensional instability) from someone who has done
this before.
