PURPOSE:To impart a silicone grease composition with improved rustproofness and lubricity by compounding a specific polyorganosiloxane, a thickener, a fine fluororesin powder and a specific thiol. CONSTITUTION:A silicone grease composition is obtained by compounding 100 pts.wt. polyorganosiloxane represented by an average composition formula of (R<1>)aSiO(4-a)/2 (wherein R<1> represents an (un)substituted monovalent hydrocarbon group; and a represents a number of 1.9 to 2.7, which means an average value); 0.01-50 pts.wt. thickener; 0.01100 pts.wt. fine fluororesin powder; and 0.01-3 pts.wt. thiol selected among compounds represented by R<2>SH (wherein R<2> represents a 10-22C (un)saturated monovalent hydrocarbon group) and compounds represented by HSR<3>SH (wherein R<3> represents a 3-16C (un)saturated divalent hydrocarbon group). |
