Use: Clearco Super-High Viscosity Pure Silicone Fluids are 100% Polydimethylsiloxane (Dimethyl) Silicone oils (CAS # 63148-62-9) that are available in viscosities ranging from 300,000cSt, 600,000cSt, 1 million cSt & 2.5 million cSt. The fluids are clear, colorless, odorless and inert. Their higher viscosity and higher molecular weight make them excellent products for a wide range of Damping applications. These fluids meet federal spec VV-D-1078 Silicone as Damping Fluid and can be used in any application that requires this specification. Clearco High Viscosity can also be used as O-Ring Lubricants, Gasket and Seal lubricants.
