DESCRIPTION:
Type 44 Heat Sink Compound is a non-silicone based, grease-like material specially blended with
thermally conductive fine metal oxide powders. Compounded from 100% synthetic base stocks, it is
designed as an alternative to silicone type heat sink compounds. This material features outstanding heat
transfer efficiency, viscosity, high dielectric strength and thermal stability.
APPLICATION:
Commonly used at the junction between a heat producing electrical device and the cooling medium, Type
44 Heat Sink Compound facilitates the transfer and removal of the damaging heat. The compound clings to
all metal surfaces and will not melt, bleed or harden over time. This product can be used anywhere a
silicone heat sink is used without the fear of silicone fluid migration.

HOW TO USE:
Type 44 can be applied by various methods including automated pumping systems, by hand, by brushing,
or by wiping. Type 44 can be applied by spraying or dipping by lowering the consistency of the product by
diluting the compound with solvents such as mineral spirits, xylene, methyl ethyl ketone, toluene, and
chlorinated ethanes.
