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 -15C to 200C
- 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
