Silicone-Free Heat Sink Compound draws heat away when applied to a component.
Also known as thermal grease, thermal paste thermal compound, CPU grease, heat paste, heat sink paste, and thermal interface material.

In electronics, heat sink compound is generally used to thermally bond a component with a mechanical heat sink. For electrical applications, it is used with thermocouple wells, thermistors, and calrods, or wherever efficient cooling is required.

Ideal for electronic applications where silicone contamination hurts solderability and increase solder defects.

Functional temperature range -40°F to 392°F (-40°C to 200°C)
Non-ozone depleting
Avoid solder defects due to silicon contamination
Easy application
Will not separate
Will not harden and crack

Applications

Electronic Repair

FAQ's

How do I figure out the shelf life of heat sink compound?

On the tubes, a little lot # is stamped into the seal on the end. For a jar it is printed on the label. That is the date of manufacture.

Instructions on insterpreting the lot #:

First 2 digits are the month (1=January - 12=December)
Third digit represents the year (1=2021, 2=2022, etc.)

The expiration date is 5 years after the DOM.

My thermal paste seems like it's getting dried out. Can I re-solvate it?

Try adding VMP naphtha (a common paint thinner) to the compound at approximately 1 part VMP to 100 parts compound. Mix thoroughly to get it back to the consistency required. This is mostly by “eyeball” so you may need a little less or a little more, depending on how dry the material is.
