Fungicides used to be added to phenol-formaldehyde lacquers, in the days
when all printed circuits were on cheap paper-based laminates (early
1950s, because the paper coating treater was poor in uniformity before
stacking prior to pressing. However, that was also in the days when
anode voltages were typically 250 V. I remember that 20 or so years ago,
some conformal coatings contained fungostats and bacteriostats, but I
haven't a clue whether they are still available. Normally, I would not
expect modern materials to support mycelia penetration, so fungostats or
fungicides should not be necessary. Beware that many fungicides are
based on ionic metal salts!
