Boron Nitride Paste

  • 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 1 cc syringe with luer lock fitting
  • Stable to 850 °C in air, 1800 °C in a vacuum. SDS available here
  • RoHS and REACH compliant
