Dave, I took it that he was referring to something along the lines of a
silicon RTV, comes in sealed containers that resemble caulk but have to be
mixed by breaking the catalyst before application. Generally light tan in
color when cured. What I have used is not generally liquid enough to fill
the fins of a heat sink, but is generally thermally conductive. We filled
the ends of the Titan 1's umbilical cables with it. Electrical leakages
are quite low, but in my experience, it won't pass a hi-pot either.
Leakage at computer voltages would be zilch however.
Cheers, gene
