I tried and tried to find this chart inside HBA. It might have been buried in any of a couple hundred threads. Rather than do that, I found it online and thought that it should have its own thread so that this important document is easily found. If anyone has a higher resolution version, feel free to add it.
For reference, styrene foams have Tg's around 210 F, Divinycel around 200 F, and ProSet epoxy of 180-192 F when post cured. Yellow still looks like it has margins, but I won't visit Mohave in the summer...
