I wrote this post a couple of months ago (shown at the end below):
Well - we have evaluated several potting compounds and are in the
process of testing some of them. But I would like to get some expert
help on this topic of potting compounds for submersion of electronics.
We have tried companies in denmark, but none that could give us
straight answers :-(
Does anyone know a consulting company or perhaps a unirversity with
that kind of knowledge abroad (preferable Europe and the US?
I'm working on a pump that is suspended in water and I need to add some
electronics to it (not more than 1 meter water level)
My initial thought was to house the electronics in a sealed
plastic/rubber enclosure, but someone pointed out that plastic/rubber
might over time absorbe water and render the electronics un-usable
Anyone got details of the behavour of plastic enclosures/potting
exposed to long
periods of total suspension i water?
