    $\begingroup$ It is interesting to know the most commonly used PCB coatings that are used in low and medium satellite orbits. But if you have information on the coatings used on geostationary satellites and interplanetary robotic vehicles, it would be great to share such information. In the countries of the post-Soviet space, urethane varnish is widespread, which is used to cover printed circuit boards (UR-231). I would like to know modern PCB coatings $\endgroup$ Oct 13, 2020 at 6:14
  • $\begingroup$ I clarified the question. My first thought when I see PCB is Polychlorinated biphenyl, not printed circuit board. $\endgroup$
