Abstract
An organopolysiloxane composition for viscous fluid couplings permits little torque variation even when used at a high temperature for an extended period of time. The organopolysiloxane composition comprises an organopolysiloxane liquid with a viscosity of 100 to 1,000,000 sq. mm/s and a platinum compound in an amount such that the amount of platinum metal relative to the liquid is 0.1 to 1,000 ppm. The organopolysiloxane liquid is typically a trimethylsiloxy-endblocked polydimethylsiloxane.
