Hi, I am looking around to understand how to choose a conformal coating for a pcb which is exposed to marine environment (well it has a case, but it is installed ~20m from the sea, facing it).
I tried looking around but, being a beginner (and a total noob regarding this), I don't know what to choose. Is acrylic ok? Is something like MG 419C suitable or is there anything better?
Most of all: how can I learn and understand how to select my conformal coating (for future projects too)?
Thanks
