CircuitWorks^® Silicone Free Heat Sink Grease
PRODUCT DESCRIPTION
CircuitWorks^® Silicone Free Heat Sink
Grease 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 oxide
ceramic, the CircuitWorks^® Silicone Free
Heat Sink Grease creates an effective heat
sink interface in electrical/electronic
equipment.
ƒ Exceeds MIL-C-47113 for thermal
conductivity
ƒ Noncorrosive
ƒ High dielectric strength
ƒ Low migration
ƒ Stable from -15°C to 200°C
ƒ Nonflammable
TYPICAL APPLICATIONS
CircuitWorks^® Silicone Free Heat Sink
Grease may be used for electronics
applications including:
ƒ Effective Thermal Coupler for any
Heat Sink Device
ƒ Nonflammable Protective Coating
ƒ High Voltage Corona Protection
ƒ Excellent for Improving Readings on
Contact Type Thermocouples
ƒ Ideal for Silicone Sensitive
Environments
