Jay,
It has been more than 12 years since my company was the Northern
California sales rep for Henkel Loctite's thermal management products.
Back then, Loctite wasn't very distributor savvy and although they
now have all the major electronic catalog distributors, they
apparently don't know how to use them to sell all of their products.
I would suggest you ask their customer service how you can quickly
obtain a sample of their Silverstrate product (aka ECF 1000, aka
Silverstrate 1000).
Be sure to tell them you are part of a large group of people who are
involved in the electric vehicle industry and that you are looking
for a good electrically conductive thermal interface product to
recommend to your group.

Paul & Al, thanks for the recommendations,
DigiKey part number 473-1121-ND - GREASE CARBON ELEC CONDUCT 2.8OZ
is my current choice, because it says it's conductive, and I can
order it today.
I believe that "LOCTITE Silverstrate" is the electrically conductive
phase change material that most closely matches my need, but the
henkel website just says
"contact customer service for ordering information"
http://www.henkel-adhesives.com/product-search-1554.htm?nodeid=8799553814529
And digikey and mouser didn't have any "silverstrate" in stock. Can
you recommend a source where I can order a small quantity? I get the
impression this might be something used by larger assembly houses
and difficult for a hobbyist to source. (at least, in $25 quantities...)
