Non-Bonding Heat Transfer Compounds
Also known as thermal paste, these boron-nitride compounds increase heat transfer between parts while preventing them from sticking. Unlike antiseize compounds, they don't conduct electricity, so you won't risk shorting out sensitive electronics. They're often used on thermocouple probes to improve accuracy. You can also use them in 3D printer heating blocks and other high-temperature areas to keep parts from fusing together.

Electrically and Thermally Conductive Grease
A high silver content gives this grease excellent conductivity for applications where electricity and heat transfer are required. It is suitable for ESD (electrostatic discharge) and EMI (electromagnetic interference) shielding applications.
NLGI viscosity grade is a rating of a grease's consistency. NLGI 2 is about the consistency of peanut butter.
Electrical resistivity is a measure of how well a material opposes the flow of electricity. The lower the rating, the more electricity it conducts.
Thermal conductivity measures a material’s ability to transfer heat. The higher the rating, the more heat it transfers.
Grease lubricates most efficiently within the listed temperature range. Melting temperature is the point at which grease will fail and run out of equipment, leaving it to run dry.

Food Industry Electrical-Insulating Grease
Use this grease in areas where there is the possibility of contact with food. Also known as dielectric grease, it lubricates and protects electrical systems. It resists water and corrosion. This grease can be used on most rubber and plastic.
NLGI viscosity grade is a rating of a grease's consistency. NLGI 1 is about the consistency of tomato paste. NLGI 2 is about the consistency of peanut butter. NLGI 3 is about the consistency of vegetable shortening.
Dielectric strength measures the maximum voltage a grease can withstand without losing its insulating properties. The higher the dielectric strength, the better its quality as an insulator.
Grease that is NSF Registered H1 and grease that meets FDA Compliant 21 CFR 178.3570 are rated for incidental contact with food. Grease that meets NSF/ANSI 51 and FDA Compliant 21 CFR 175.300 are rated for direct contact with food. Grease that meets NSF/ANSI 61 is certified for use with components that come into contact with drinking water.
Grease lubricates most efficiently below the maximum temperature. DuPont Molykote 4 Electrical Insulating Compound also acts as a moisture barrier.

Grease lubricates most efficiently below the maximum temperature. Nonmelting grease can be used at temperatures above the maximum temperature briefly, but then will break down more quickly.
Molykote 5 Compound is for use on insulators, bushings, and high-current switches.

Electrically Conductive Antiseize Lubricants
Copper allows these lubricants to conduct electricity, while graphite gives them good chemical and corrosion resistance. Also known as thread lubricants, antiseize lubricants prevent threaded fasteners and close-fitting parts from locking together due to corrosion, contamination, or heat.
Loctite® C5-A Copper-Based Anti-Seize lubricants can be used with salt water and petroleum-based chemicals. LB 8065 comes as a stick for no-mess application.
Lubricants that meet MIL-A-907F and MIL-PRF-907F have been tested to prevent corrosion of copper and for antiseize properties when used with steel nuts and studs.
Dielectric strength measures the maximum voltage a lubricant can withstand without losing its insulating properties. The higher the dielectric strength, the better its quality as an insulator.
Electrical resistivity is a measure of how well a material opposes the flow of electricity. The lower the rating, the more electricity it conducts.

Heat-Transfer Potting Compounds
Formulated to draw heat away from sensitive electronic components, these potting compounds have higher thermal conductivity than standard potting compounds. Use them to encase electronic assemblies for protection from dust, chemicals, moisture, mechanical shock, and vibration. Rigid and wear resistant, epoxies are the strongest of the potting compounds. They have excellent chemical and moisture resistance, withstand a wide range of temperatures, and provide excellent electrical insulation.
Cartridge potting compound requires a gun and mixer nozzle (each sold separately) to dispense.

Conductive Liquid Gallium
Often used as a safe alternative to mercury in thermometers, thermostats, and switches, these gallium alloys are also good for transferring heat and electricity in soft electronics that must bend and flex. With a low melting point, they’re a liquid at room temperature. These alloys wet (stick to) both metallic and nonmetallic surfaces, and can even be used as a high-temperature lubricant for bearings. They will, however, dissolve aluminum at room temperatures and many other metals at higher temperatures. They’re also known as Galinstan.
Gallium alloys with 66.5% gallium have a lower melting temperature than those with 75.5% gallium. They are not, however, as good for transferring heat.
Gallium alloys with 75.5% gallium are better than those with 66.5% gallium for transferring heat. They also have a higher melting temperature.
