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.

Penetrating Lubricants for Electrical Applications

Protect electrical components—these lubricants insulate and block moisture, preventing electrical malfunctions. They cut through dirt, grease, and rust to clean connections and relays, leaving behind a thin film for long-lasting protection.

Cannot Be Sold Outside United States—These lubricants cannot be sold outside the United States due to product labeling requirements.

Dielectric Strength—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.

Clean Room Grease

Highly pure and with no additives to contaminate sensitive environments, use this grease in clean rooms and electronic assembly workstations. It is nonconductive, chemically inert, and can withstand extreme temperature swings. This long-lasting grease also has an indefinite shelf life.

Grease lubricates most efficiently within the listed temperature range.

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.
