I had a large number of power resistors I needed to mount to a large metal plate for thermal control and this compound worked really well. I am getting dissipation through the plate better than I expected and the paste was easy to use and keep contained during the assembly process. I have been a big fan of some specialty Dow products over the years and this thermal paste delivered as I would expect!
