ABSTRACT:
In the fluid for viscous coupling according to the present invention, organopolysiloxane is used as base oil, and by adding phosphorus type anti-wear agent or by adding the combination of said phosphorus type anti-wear agent with antioxidant or by adding the combination of phosphorus type anti-wear agent with sulfur type anti-wear agent and/or zinc dithiophosphate type anti-wear agent or further by adding antioxidant, it is possible to increase heat-resistant property without changing the viscosity when viscous coupling is in operation and to provide the fluid for viscous coupling with few wear fragment iron quantity and with high durability.
In the fluid for viscous coupling according to this invention, organopolysiloxane is used as base oil, and by adding metal deactivator and/or corrosion inhibitor, or by adding anti-wear agent and/or antioxidant, it is possible to prevent the viscosity change for long time when viscous coupling is in operation and to provide the fluid for viscous coupling with high durability.
