Abstract
An electrically conductive silicone composition comprising an electrically conductive filler; organopolysiloxane mixture comprising a catalyst which promotes the addition of Si-bonded hydrogen onto alkenyl multiple bonds; an organopolysiloxane having at least two alkenyl groups per molecule; an organopolysiloxane having at least two silicon-bonded hydrogen atoms per molecule; optionally, a fluid organopolysiloxane having a viscosity less than about 1000 centipoise; and optionally, an organopolysiloxane gel formulation, the composition, when cured, having a Shore A Durometer hardness of less than or equal to about 60 measured according to ASTMD-2240 and an electrical resistivity of less than or equal to about 10−6 ohm-cm.
