Hi

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?

Thanks

Klaus

QOUTE

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 exposed to
long
periods of total suspension i water?

Hello Klaus,

I'd ask larger companies such as 3M that make potting compounds for the
telecom market (where stuff usually needs to tolerate water):
http://products3.3m.com/catalog/us/...us_mro_3_0/command_AbcPageHandler/output_html

This link will probably line-break but it's their Utilities &
Telecommunication business unit.

Others:
http://www.mgchemicals.com
http://www.fongyong.com.tw/

In Denmark you could probably look for larger marine suppliers.

I would be inclined to drop MG Chemicals from the list of potential
potting compound suppliers, based on my experience with their
products, and add MasterBond
http://www.masterbond.com/overview.html#oelec
which has excellent technical support, and although they are a US
company like 3M.

Have you tried asking manufacturers of potting compounds for marine use?
If they don't have your answers, they should be able to offer referrals.

These guys are global, UK based: http://www.electrolube.com/docs/bresin.html

Not specifically a potting compound, but you might try the
Smooth-on brand polyurethane resins, as I've been meaning to
after having less success than I hoped for with Polytek.
The right PU resin is as flexible as you choose and incredibly
tough - vis roller-blade wheels. Make sure you get one that
mixes with low viscosity so you can vacuum it and get all the
bubbles out.
