Steve,
Just remember that if
you use silicone conformal coatings, you better have a second set of spray guns.
Silicon conformal coat materials is difficult to clean and can clog the spray
guns if urethane conformal coating is used.
In my prior life, we had
2 separate sets of tooling and 2 separate spray booths to keep silicones away
from urethanes. We used silicones, paralyne, and urethane conformal coatings for
space applications, with success depending upon the customer requirements. Not
only were we concerned with moisture resistance, but we were very concerned with
out gassing.
Hope this
helps.
Good
Luck.

Hi All!
I know when you look up properties
for Silicone conformal coating, it usually states that it has good moisture
resistance, but is it really that good?
I've heard that it is somewhat
permeable to moisture, that if you were worried about moisture, and the
assembly were going to see the outside environment, you would be better off
with an acrylic, or urethane coating.
Any
thoughts?
Thanks!
