A room temperature-curable electrically conductive fluorosilicone rubber composition comprises: (A) a fluoropolysiloxane capped at the molecular terminals with hydroxyl groups having a viscosity at 25° C. of from 1,000 to 1,000,000 mPa·s; (B) fine silica powder having a BET specific surface area of not less than 50 m2/g; (C) a carbon black; (D) a fibrous carbon allotrope having a graphene structure; and (E) a crosslinking agent. Component (D) is comprised in an amount of not less than 1.5 parts by mass per 100 parts by mass of component (A). The room temperature-curable electrically conductive fluorosilicone rubber composition is cured to form a cured product having both superior post-cure physical strength and electrical conductivity. Also, the room temperature-curable electrically conductive fluorosilicone rubber composition has viscosity that enables superior handling, and provides superior post-cure surface smoothness, solvent resistance, and adhesion. |
