CircuitWorks Silicone Free Heat Sink Grease CW7270 facilitates heat transfer away from electrical/electronic components and into heat sinks. This silicone-free compound shows no creep or migration over a wide temperature range. Thickened with a proprietary thermally conductive zinc oxideceramic, the CircuitWorks Silicone Free
Heat Sink Grease creates an effective heat sink interface in electrical/electronic equipment.

FEATURES:

  •  Exceeds MIL-C-47113 for thermal conductivity
  •  Noncorrosive
  •  High dielectric strength
  •  Low migration
  •  Stable from -15C to 200C
  •  Nonflammable

TYPICAL APPLICATIONS: CircuitWorks Silicone Free Heat Sink Grease CW7270 may be used for electronics
applications including:

  •  Effective Thermal Coupler for any Heat Sink Device
  •  Nonflammable Protective Coating
  •  High Voltage Corona Protection
  •  Excellent for Improving Readings on Contact Type Thermocouples
  •  Ideal for Silicone Sensitive Environments
