Abstract
A two-part formulation for a potting composition is provided that includes a part A including silicone polymer precursors, boron nitride present in an amount of from 20 to 60 total weight percent as particulate or 1 to 8 total weight percent as boron nitride nanotubes, a platinum or rhenium addition catalyst. A part B includes a hydride functional siloxane operative to cure the silicone polymer precursors and devoid of said platinum or rhenium addition catalyst. When cured in the presence of the voltage producing substrate, a potting is formed that has high thermal conductivity and low electrical conductivity.
