Abstract:
Provided is an antistatic silicone rubber composition. The composition comprises at least one lithium compound selected from the group consisting of a lithium amide, lithium silylamide, lithium alkyl phosphate salt, lithium phenoxide, lithium sulfate and a lithium permanganate, in an amount of from about 0.1 to about 15 mass % of the composition. In general, the composition may comprise: (A) an organopolysiloxane having at least two silicon atom-bonded alkenyl groups per molecule; (B) an organopolysiloxane having at least two silicon atom-bonded hydrogen atoms per molecule; (C) a hydrosilylation catalyst; and (D) the at least one lithium compound as described above. The composition generally exhibits good curability, and cures to form a silicone rubber exhibiting excellent antistatic properties.
