Conclusion:

In 60 minutes testing, the thermal resistance is similar between coating and none coating housing, but the temperature reading is lower on the BN coating application.  The BN coating provides better thermal management.

Advantages

 

TSD BN thermal coating improves thermal management by conducting thermal transfer away from the heat source.
