<p>PURPOSE:To obtain a conductive compsn. which is excellent in storage stability, adheres strongly to an adherend even after sulfurization, and has conductivity hardly changing with environmental temp. by compounding a specific polyorganosiloxane, a specific acetylene black, a specific silane, and a solvent. CONSTITUTION:This compsn.contains 100 pts.wt. polyorganosiloxane represented by the mean unit formula (wherein R is a monovalent hydrocarbon group; and a is 1.98-2.02), 10-100 pts.wt. carbon black produced by the exothermal decomposition of acetylene and having a chlorine liq. absorption of 12ml/5g or lower and an iodine adsorption of 50mg/g or lower, 100-1,000 pts.wt. solvent, and a silane or low-polymn.-degree polysiloxane having at least two moisture- hydrolyzable groups bonded to Si atoms through 0 or N atoms in an amt. of the hydrolyzable groups of 10-500 times that of silanol groups contained in the polyorganosiloxane and gives a coating film with a smooth surface.</p> |
