Product Description

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.
