Resend of Burnout Query

RP folks:

My last post may have been chopped in half electronically, so I'm
reposting my question.

I'm building a pattern from SL5170 resin on an SLA250. Does anyone who has
experience in burnout of this material tell me the maximum temperature
for burnout? Also, any tips on what to expect as far as expansion
stresses, ashing, etc. that could destroy my mold would be appreciated.

I've read the TGA data in the resin handbook, but I'd like the users'

Note: This is not a quickcast pattern and the thickest section
in this pattern is about 4mm.

Many thanks,
