Use: Clearco High Viscosity Pure Silicone Fluids are clear, colorless and odorless linear Polydimethylsiloxane oils (Polydimethylsiloxanes) that range in viscosities from 5,000cSt, 10,000cSt, 12,500cSt, 30,000, 60,000cSt, & 100,000cSt. They are characterized by their high damping action, excellent lubricity, inertness to plastics, rubbers and metals, high dielectric strength, high resistance to shear, thermal stability, wide service temperature range and low viscosity change at temperature.
Due to their high viscosity, inertness and lubricity, High Viscosity Silicone Fluids are widely used as lubricant for o-rings, gaskets, valves and seals.
Clearco High Viscosity Pure Silicone Fluids meet Federal Specification VV-D-1078 "Silicone as Damping Fluid". They are used in a wide range of military, industrial and avionic gauges, meters, instruments, and monitoring systems.
