I thought the HDT is higher than the cure temperature.  If it was cured at
room temp, then after reaching the HDT a new higher HDT was developed.  The
is a limit however as the HDT and the new cure temp become the same and you
have reached the max.

I am sending this to Gary Hunter, Shell Oils resin man for his comment.

I called up Jeffco Epoxy and talked to one of their guys about their 1307
resin system.  He said that their resin had a HDT (Heat Distortion
Temperature) of 190 degrees F.  ...snip...
As for me, I'd rather have a higher HDT resin system.
