Abstract
The shortcomings inherent in prior art coupling fluids are eliminated by combining 1) a polyorganosiloxane fluid as the base oil with 2) sulfur or certain sulfur compounds and 3) at least one cyclic organosiloxane. These three ingredients form a suitable coupling fluid for use in viscous coupling systems.
