Someone asked the questions regarding high humidity and the best conformal
coating to use and I read 4 different answers:  Acrylics, urethanes,
paralyene and Silicone.  I have always understood that acrylics were the
least moisture resistant, paralyene the most moisture resistant and
urethanes the most commonly used for moisture resistance on CCA's.  Anyone
care to clarify?

Acrylics tend to have the best performance in high moisture environments, as
long as the temperatures are not extremely high.
