If you send and email to the technical department at SP systems, they will be able to tell you theirs resins thermal conductivity, I guess most epoxys are more or less conductive.

Very nice to have a reply on such an oldie!
There are some more questions posted by me and pending a reaction.
Reading and reading again makes anyone more eager to READ AGAIN I hope.
Thank you.
