Description


Momentive SF1147

Methyl alkyl silicone hydraulic fluid by Momentive is a unique hybrid fluid engineered with hydrocarbon and silicone elements. Known for its exceptional performance in extreme temperatures ranging from -54°C to 232°C, SF1147 ensures superior lubricity, thermal endurance, and radiation resistance. It is used extensively across industries for nuclear equipment, hydraulic systems, snubbers, penetrating oils, and shock absorber applications. It has excellent viscosity-temperature characteristics, minimal thermal expansion, and no additive fallout.

Use of the Product
SF1147 is specifically developed for use in:

  • Closed or inerted hydraulic systems

  • Nuclear equipment lubrication

  • Shock absorbers

  • Vacuum pump systems

  • Penetrating oil and additive blending

  • Flexible cable lubrication

  • High-stress industrial machinery

Applications

  • Sintered-bronze and stainless-steel bushing lubrication

  • Hydraulic fluid for extreme temperature environments

  • High-radiation resistance zones (nuclear plants, reactors)

  • Vacuum pumps and shock-absorbing mechanisms

  • Additive base for custom lubricant formulations

  • Cable lubrication (steel on plastic)

  • Penetrating and rust prevention oil for metal machinery
