Super High Viscosity Pure Silicone Fluids : Guide
Super Hi-Vis Silicone Fluids are known for their high damping action, extremely high viscosities, and high molecular weight, making them ideal for demanding applications. These Silicone Fluids offer excellent lubricity, inertness to plastics, rubbers, and metals, as well as high dielectric strength and thermal stability. They also feature high resistance to shear, a wide service temperature range, and low viscosity change with temperature.
Clearco High Viscosity Pure Silicone Fluids meet Federal Specification VV-D-1078 for Silicone as Damping Fluid. These fluids are widely used in military, industrial, and avionic gauges, meters, instruments, and monitoring systems. They are also highly effective as lubricants for o-rings, gaskets, valves, and seals, providing smooth operation in critical applications.
