Jim,
Depends on what you mean by best and by plastic.  It is more a question of 
what is your end use environment, how hermetic is your enclosure, what is 
the design life of your product, and what are the consequences of failure. 
 There are a wide range of acrylic coatings, or modified acrylic coatings, 
to choose from.  Not all are equal.

Subject
[TN] Conformal Coating Plastic Parts






Good Day all,
It seems lately that more of our designs (defense, aerospace) are using 
military qualified plastic parts, mainly because of availability.  I 
recently heard that acrylic conformal coating isn't the best coating of 
choice when applied to plastic parts.  I was wondering what the Forum 
thinks regarding this matter.
