8616 Technical Data Sheet 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 Usage Parameters Properties Value Shelf life 5y Theoretical coverage for 3 mL syringe a) <1 180 cm2 [<0.64 ft2] a) Estimate based on 25 m [1.0 mil] thickness and 100% transfer efficiency. Temperature Ranges Properties Value Constant service temperature -68 to 165 C [-90 to 329 F] Storage temperature limits -10 to 40 C [14 to 104 F] IS0 9001:2015 Quality Management System.
