Paralene and moisture cure silicones will work well for your
application, although there may be some CTE problems with silicones.
Try Dow Corning, Grace Specialty Polymers, or Shin-Etsu for silicones
or Specialty Coating Systems for Paralene.

On Conformal Coatings:
I was wondering if anyone can recommend manufacturers of a conformal coating
that will be placed on an PCB with a complex topography. Some of my require-
ments are as follows:
-high dielectric strength
-good adhesion to flux residues
-UL and/or Mil-Spec approval
-able to withstand high temperature applications (~130 C) for extended
periods
-fast cure
-easy to apply
-easy to rework
-moisture resistant
-solvent-free
-no outgassing
-volatile organic compound-free (VOC-free)
-relatively same thermal expansion coefficient as PCB panel
