Boron Nitride Paste offers improved thermal performance by optimizing heat distribution in your 3D printer’s hot block and also serves as a reliable potting agent for secure installation. Its non-electrically conductive nature, high-temperature stability, and adherence to safety and environmental standards provide a safe and efficient thermal solution.

Improved Thermal Performance
Specially formulated to ensure efficient heat transfer, Boron Nitride Thermal Paste optimizes heat distribution within your 3D printer’s hot block by minimizing air gaps between the cartridges and the hot block. By promoting even heat dispersion from the heater cartridge to the hot block, Boron Nitride Paste enhances hot block efficiency, extends your heater’s lifespan, and ensures more accurate temperature measurement.tight deadlines.

Reliable Potting Solution
Boron Nitride Paste is the ideal potting agent when installing heaters and temperature sensors. Mosquito® and Copperhead® hot blocks use retaining screws to hold the heater and sensor in place instead of clamps (which can put unnecessary pressure on the cartridges and reduce their lifespan), requiring Boron Nitride Paste as a potting agent to hold the cartridges firmly in place.

Formulated for Safety
Boron Nitride Paste eliminates the risk of short circuits by being non-electrically conductive after being heated to 100°C, safeguarding your heater cartridge and thermistor. With high-temperature stability up to 850°C in air and 1800°C in a vacuum, it excels in demanding printing applications. RoHS and REACH compliant, it meets strict safety and environmental standards. For additional information on safety and handling, the SDS (Safety Data Sheet) is available in the downloads below.

Water-Soluble Cleanup
Boron Nitride Paste offers the convenience of water solubility, allowing easy cleanup and maintenance. When disassembling or reconfiguring your 3D printer, carefully clean the components with water to remove the paste without any residue or greasy buildup.
