- Heatsink Compound
This is a 5g syringe of white heatsink compound (aka thermal grease, thermal paste, thermal goo). Use this whenever you're connecting a component to a heatsink, it'll really help to dissipate even more potentially damaging heat.
This compound is composed of 50% silicone, 20% carbon, and 30% metal oxide. It has a thermal conductivity of 1.172 W/(mK), which should be plenty for voltage regulators, MOSFETs, motor drivers, audio amplifiers, etc.

Variable Load Hookup Guide - Revised
May 25, 2018
This tutorial will show you how to assemble and use SparkFun's Variable Load board. It can be used to test stability of the power supply under various loads, battery lifetime, safety cutoffs, and other design elements of power supplies under test.
Core Skill: DIY
Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.
Skill Level: Noob - Basic assembly is required. You may need to provide your own basic tools like a screwdriver, hammer or scissors. Power tools or custom parts are not required. Instructions will be included and easy to follow. Sewing may be required, but only with included patterns.

Heat Sink Compound
This is just a heat sink compound. It is not an adhesive. You need a way to secure the part to a heat sink.
How much area can this cover if you screw the heat sink the the board? I have an 70W amp that I need to build that will get really hot
is there any way to cure this compound so it is solid?
Is this product electrically conductive?
Can you guys ship this internationally or are there laws preventing shipping this on aircraft due to restrictions on liquids and "hazardous: materials been shipped in aircraft?
Does this Dry? I borrowed some silver thermal compound and It had a 600hr set time... never the less... it still hasnt set...
Little late... No. Not that I know of. I used somw of this, and the components it's on (granted, barely used) are still able to wipe this off of.
Which metal oxide is that 30%?
This is a perfect Heat Sink Compound.
What is "Moment Beared Temperature"?
Hey I`d also love to be able to buy some Solder Paste from sparkfun, even if it costs the same as Digikey
Wish granted! TOL-10448
This looks fine, but for that (cheap as it is) price you can get some really good thermal compound that would be suited to a high end cpu as well as some regs.
