Technical Data Sheet
8616
Super Thermal Grease II
Description
8616 is a paste with high thermal conductivity. It is designed to reduce thermal resistance between irregular
metal surfaces. It is most commonly used to improve heat flow between heat sinks, LEDs, motors, and
heat-generating electronic components such as CPUs, GPUs, and power components.
Features and Benefits
• Thermal conductivity of 1.8 W/m·K
• Silicone-free
• Broad service temperature of -68 to 165 °C (-90 to 329 °F)
• High dielectric strength
• Excellent corrosion resistance—passed ASTM B117 salt fog test 1 000 hours
• Non-bleeding
• Non-electrically conductive
• Long service life
