Heat sink compound

[Eric Schumacher]

Hi 
Dielectric grease is a silicone compound manufactured by Dow Corning.
Thirty or fourty years ago it was used to promote heat transfer between
semiconductors and heat sinks. Heat sink compound is often the same grease
loaded with alumina or some such thermally conductive oxide. Niether are
electricaly conductive but dielectric grease is eaisly displaced.
Dielectric grease is excellent for use on electrical connections thay may
get damp as it is very impervious to water. Heat sink compund, since it is
loaded with ceramic should never be used in these applications.  If you
really want high conductivity both heat and electrical, silver loaded
dielectric grease is available, electricians use it between bus bars when
they bolt two together.
Lotsa Luck Eric
