If anyone knows of any organic substance able to survive these conditions (1050
C /wet O2), please let me know...

Bruno -

SU-8 starts degrading at around 300 C and begins to decompose as the
temperature approaches 400 C in an oxidizing environment. Even in a
vacuum, it degrades significantly at about 400-450 C. I don't think
there's any chance of it surviving the stated conditions.
