Silicone Heat Transfer Compound (Heatsink Grease) - 4g
MG Chemicals Part Number: 860-4G

As with most types of grease, a little bit goes a long way. In fact, this small 4 gram package is probably more than enough to cover several heatsinks.

Designed for use in transferring heat away from electrical and electronic devices such as; transistors, power diodes, semi-conductors, ballast's and thermocouple wells. High thermal conductivity, high dielectric constant, high dissipation factor, use with heat sinks or metal chassis, will not dry or harden. Contains zinc oxide and polydimethyl siloxane.

Features:
  • High thermal conductivity
  • High dielectric constant
  • High dissipation factor
  • Use with heat sinks or metal chassis
  • Will not dry or harden
  • Contains zincs oxides and polydimenthyl siloxane
