Abstract

A mixture of an organopolysiloxane fluid, a zirconium-containing organosiloxane compound having at least one zirconium atom and at least one siloxane unit, and a cerium-containing organosiloxane compound having at least one cerium atom and at least one siloxane unit is an organopolysiloxane viscous coupler fluid which can be used in gear systems. These coupler fluids undergo little viscosity increase or decrease and little torque variation at elevated temperature and under high shear over long periods of time.
