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® LB 8008 C5-A Copper-Based Anti-Seize—Loctite® C5-A Copper-Based Anti-Seize lubricants can be used with salt water and petroleum-based chemicals.

LB 8065 C5-A Copper-Based Anti-Seize—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.

MIL-A-907 and MIL-PRF-907—Lubricants that meet MIL-A-907 and MIL-PRF-907 have been tested to prevent corrosion of copper and for antiseize properties when used with steel nuts and studs.

Cannot Be Sold To—Lubricants that cannot be sold to the areas listed exceed local regulatory limits on VOC (volatile organic compounds).

Electrically and Thermally Conductive Grease

Jar

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.

Grease lubricates most efficiently within the listed temperature range.

2 NLGI Grade—NLGI 2 is about the consistency of peanut butter.

Melting Temperature—Melting temperature is the point at which grease will fail and run out of equipment, leaving it to run dry.

Electrical Resistivity—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—Thermal conductivity measures a material’s ability to transfer heat. The higher the rating, the more heat it transfers.

Cannot Be Sold To—Product regulations restrict sales to the listed jurisdictions/areas.

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.

Conductive Gallium

A safe alternative to mercury in thermometers and thermostats, gallium transfers heat and electricity without toxic vapor that can be inhaled. Also known as Galinstan. Its low melting point means it's liquid at room temperature. When used next to parts that generate concentrated heat, it dissipates the heat quickly, making it good thermal interface material. It also allows electricity to pass throughout it, so it's often used in switches and electronics that must bend and flex.

Gallium clings to both metallic and nonmetallic surfaces such as glass and quartz. However, it eats away at most metal when used at high temperatures and dissolves aluminum even at ambient temperatures.

When choosing gallium, keep in mind its composition. The higher the gallium and indium content, the better it is at transferring heat. Gallium with tin reduces the melting point, but also decreases how well it transfers heat.
