Abstract
A thixotropic silicone rubber composition comprising (A) an organopolysiloxane having on the average at least two alkenyl groups in a molecule and a degree of polymerization of up to 1,200, (B) a liquid organohydrogenpolysiloxane having at least two hydrogen atoms each attached to a silicon atom, (C) aluminum hydroxide, (D) an addition reaction catalyst, (E) a thixotropic agent, and optionally (F) a tackifier cures at room temperature or elevated temperature into a silicone rubber having high strength and electrical insulating properties sufficient to serve as a high-voltage electrical insulator. The composition is so thixotropic that it may be used in repairing chipped portions of insulators.
