Abstract
A composition contains: (a) a polyorganosiloxane component comprising one or a combination of more than one poly-organosiloxane; (b) a filler treating agent comprising alkyltrialkoxysilane and trialkoxysiloxy-terminated diorganopolysiloxane; (c) 90-98 weight-percent of a combination of thermally conductive fillers comprising: (i) 25-40 weight-percent of thermally conductive filler particles having an average particle size of 70-150 micrometers and selected from one or a combination of aluminum oxide and aluminum nitride particles; (ii) 15-30 weight-percent thermally conductive filler particles having an average particle size in a range of 30-45 micrometers selected from one or a combination of aluminum oxide and aluminum nitride particles; (iii) 25-32 weight-percent aluminum oxide particles having an average particle size in a range of 1-5 micrometers; and (iv) 10-15 weight-percent thermally conductive filler particles having an average particle size in a range of 0.1 to 0.5 micrometers; where weight-percent is relative to composition weight.
