Boron Nitride Paste is a specialist thermal interface compound designed for 3D printer heater cartridge installation. Applied to the cartridge heater hole in your heat block, it dramatically improves heat dissipation from the cartridge, extending component lifespan. Unlike conductive anti-seize compounds, boron nitride's non-conductive properties eliminate the risk of electrical shorts to your heater or thermistor. Rated stable to 850 °C in air and 1800 °C in vacuum, it's engineered for demanding thermal management in hotend assemblies like Mosquito® and Copperhead® systems. Thermal paste for improving conduction Acts as a release agent Unlike anti-seize compounds, Boron Nitride is not electrically conductive, which eliminates the risk of shorting out your heater cartridge or thermistor Use the included applicator to coat the cartridge heater hole in your 3d printer heat block. Insert the cartridge heater while the paste is still wet, then let dry. The boron nitride boosts dissipation of heat from the hot section of the cartridge heater, improving its life. Retails in 5 cc syringes with luer lock fittings. Stable to 850 °C in air, 1800 °C in a vacuum. SDS available here. How to Apply 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. Boron Nitride is so effective, that NASA is experimenting with it in high temperature applications on their spacecraft for the first manned mission to Mars. How is this related to 3D printing you may ask? Well, this paste elevates heat conduction between components, ensuring that your printer is working at maximum capacity, giving your hot block the even heat distribution it needs to deliver the highest quality print in the shortest amount of time. Also, unlike anti-seize compounds, Boron Nitride is not electrically conductive, which eliminates the risk of shorting out your heater cartridge or thermistor. The boron nitride particles in our compound are in an aqueous suspension. Once it’s heated, the liquid portion of the suspension evaporates, leaving behind a crumbly, clay-like paste. This paste has a tightly packed crystalline microstructure, and is extremely conductive (31.4 W/mK at 100 °C). Those properties make it an ideal candidate for NASA, and an ideal candidate for your printer. Bring a little space technology to your printer, and get better heat conduction.
