Description: Medium Viscosity Silicone Damping Fluids are clear, colorless, and odorless linear Polydimethylsiloxane fluids / PDMS Silicone Oils that range in viscosities from 50cSt to 1,000cSt (centistokes) @ 25°C. They are characterized by their low pour points, high flash points, low viscosity‐to‐temperature coefficients (viscosity changes little even at extremely low temperatures), Newtonian behavior under shear,, excellent lubricity, high dielectric strength and RI values ranging from 1.3970 to 1.4000.

Silicone Damping Fluids meet Federal Spec VV‐D‐1078 "Silicone as Damping Fluid". They are used in a wide range of military and industrial applications to dampen vibration, dampen pulsation, and dampen torque. The other main application is for use in Flow Control, Temperature Control and Pressure Control Instruments.

Medium Viscosity Silicone Damping Fluids are particularly effective for use in instruments and gauges that will operate over a wide temperature range. Silicone fluids are hydrophobic and prevent humidity from entering the gauge/instrument housing. This is very important. At low temperatures, water condensation can freeze and cause damage to the sensitive parts within the gauge/instrument housing.

Ultimately, Silicone Damping Fluids will extend the service life of the equipment that it fills and provide more accurate readings even in the harshest of conditions.
