Why do you need a Heat
Transfer Compound?
Improves thermal connections between
heat sinks and components.
Use Heat Transfer Compound on all electric and
electronic devices where efficient heat transfer
cooling through thermal coupling is required:
4Semiconductor mounting devices
4Thermal joints
4Ballast heat transfer mediums
4Power resistor mountings
4Thermocouple wells
4Transistor diodes
4Silicone rectifier base and mounting studs
This Non Silicone Heat Transfer Compound is designed
to eliminate the potential problems of silicone-based
compounds caused by migration and component con-
tamination. Designed for use in transferring heat away
from electrical and electronic devices such as transistors,
power diodes, semi-conductors, ballasts and thermo-
couple wells.
4High thermal conductivity
4High dielectric constant
4High dissipation factor
4Use with heat sinks or metal chassis
4Will not dry or harden
4Meets MIL-DTL-47113D
