| abstract |
The present invention relates to (A) an organopolysiloxane having at least two aliphatic unsaturated hydrocarbon groups in a molecule, (B) a filler (C) comprising an aluminum powder and a zinc oxide powder and at least two organohydrogens having SiH groups in one molecule When the storage elastic modulus G 'and the loss elastic modulus G' 'of the silicone composition were measured using a viscoelasticity measuring device comprising a platinum group metal catalyst and (D) a platinum group metal catalyst capable of measuring shear elasticity, Which gives a cured product having a G 'after 10,000 seconds, a G' after 10,000 seconds and a G 'after 7,200 seconds of 100,000 Pa or less and a G' exceeding G ' . Accordingly, a silicone composition and a method of manufacturing a thermally conductive silicone composition excellent in friability, spreadability, and thermal conductivity are provided. |
