Super High Viscosity Pure Silicone Fluids : Guide
Super Hi-Vis Silicone Fluids are characterized by their high damping action, extremely high viscosities, high molecular weight, 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.
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, and o-ring, gasket, valve and seal lubricants. In addition, they are used to coat and lubricate a wide range of o-rings, gaskets, valves and seals…
