Simon,
      We deposit our SAM/organo silanes at temperatures between 25 and
200 degrees C.  Using proprietary dehydration loops to remove the
moisture from the surface ensures the only silane grabber is the
hydroxyl ions. Following this approach for the last 25 years and close
to 2,000 silane deposition units we produce a surface that is impervious
to alteration by ambient moisture.  The temperature will obviously be no
problem, I doubt the pH will present any problem.  The film deposition
in water may be a problem but I doubt it.  Lets do some free tests with
the organo silane of your choice.  Contact me directly and I will
discuss the action of a multitude of organosilanes and surfaces.
