Beschreibung
Zusammenfassung:	A circuit board water-proofing coating composition is provided comprising: at least one passivating agent, preferably containing a molecule comprising a thio- functional group, desirably a thiol group, an azolic moiety, or an azole, and combinations thereof; at least one binder component comprising an organic or inorganic film-forming polymer, and / or one or more polymer pre-cursors polymerizable on a substrate surface; and optionally one or more additive(s); also provided are methods of making and using the coating composition and coated circuit boards.
