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.

No mixing required --these potting compounds come ready to apply. Use them to encase electronic assemblies for protection from dust, moisture, mechanical shock, and vibration. Softer and more flexible than epoxies and urethanes with the widest temperature range, silicone potting compounds are the best choice for high-temperature applications and electronics exposed to thermal cycling. They have good moisture resistance but poor chemical and abrasion resistance. Silicones provide excellent electrical insulation. They're also known as RTV (room-temperature vulcanizing).

Potting compounds that cannot be sold to California exceed local regulatory limits on VOCs (volatile organic compounds).
