removable potting compound ?

Posted by Pogo on March 29, 2007, 10:00 pm

Is there such a thing as a removable potting compound of the type used =
in electronics?

I'm looking for something to secure wires and/or screw settings against =
vibration and strain but that can be removed for resoldering & =
adjusting. Maybe just plain silicone sealant is the best bet, but in the =
past when I have tried using it in thickness greater than 1/8" or so it =
either did not cure or took forever to do so! I want something I can =
apply once and cure in 24-48 hours at the most. I want to be able to =
remove it later without destroying the product it is used on ( most =
likely a circuit board of some type; DC-DC converter with screw =
terminals, etc. ... )

Thanks !

Have you tried rubber cement?

Best,

No, but that's and idea I hadn't even considered. Might be more what I'm =
looking for. Something that can be peeled off later sounds like the =
ticket!

There is a two-part Room Temp. Vulcanizing Silicone putty than will cure in
about a half hour. Nothing will stick to it so you will have to devise
mechanical methods. My supplier has disappeared but I'd try McMaster Carr
first.

More RPM = more windings or stronger magnets ?
