Need To coat an electronic control card against H2S
Need To coat an electronic control card against H2S
(OP)
Hello everyone, i need URGENT HELP with finding a way (a product or a company) that can protect an electronic card (its the controller card from a rectefier control module)against corrosive agents, especifically against H2S (hydrogen sulfide). What i know is that Epoxy is used to do this. I really hope someone can help out with these, i need to find the fastest way to treat this cards in order to put them to work in an area that may or may not contain some level of H2S gas (although i know that this gas cant be present in a place where humans work, because in a concentration as low as 100 ppm leads to eye damage and 320 leads to pulmonary edema with the possibility of death).

I'm currently working on the same issue, so any detailed information is welcome. Currently my approach is different.

It should be noted that there may be some heat dissipation issues if you coat hot or heatsinked parts with anything.

You could google on "potting compound" rather than conformal coating. Typcially you get a small plastic box (without a lid). Put the board inside the box and pour in the potting compound. This holds the potting compound so you get a defined shape and no drips.
