urethane is far better choice.

Subject: [TN] Silicone conformal coating


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!
