## Overview

Boron Nitride Paste by Slice Engineering is a high-performance thermal interface compound designed to optimize heat transfer in 3D printer hot blocks, thermowells, and sensors. With a thermal conductivity of 31.4 W/mK and stability up to 850°C, it ensures precise temperature control while being non-electrically conductive to prevent shorts. RoHS and REACH compliant, this water-soluble paste offers easy cleanup and reliable potting for heaters and sensors, making it an essential upgrade for professional-grade 3D printing and thermal management.

## Description

Boron Nitride Paste offers improved thermal performance by optimizing conductive heat transfer through 3D printer hot blocks, thermowells, RTD sensors, thermistors, thermocouples, and more. This paste is non-electrically conductive, stable at high temperatures, and acts as a reliable potting agent. Specially formulated to ensure efficient heat transfer, it optimizes conductive heat transfer through 3D printer hot blocks, thermowells, RTD sensors, thermistors, thermocouples, and more. It minimizes air graps and promotes even heat dispersion across components. When used in 3D printing, Boron Nitride Paste effectively transfers heat from the heater cartridge to the hot block and optimizes the sensor's capability of reading that heat. This enhances the effiency of your hot block, extends your heater’s lifespan, and ensures accurate temperature measurement.It's also 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 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. It also 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.

Review: If you upgrade a hotend use this. - Works as specified. Many of the heater cartridges are a loose fit and if they do not contact metal to metal well. There will be inconsistent heating of the block with just a set screw and potential thermal runaway issues. This compound has a high heat transfer. No more struggle to 300c+. Smooth consistent heating and stable temp holds. It's water-based instead of grease, so it cleans easy. Slice Engineering kept the price reasonable for a home hobby 3d printing compared to computer focused compounds. Product is a grand slam home run.
Review: This works really well for heater cartridges and thermocouple sensors. - I used this to coat the heater cartridges and K type sensor for a hot plate project. I coated four cartridges (1.57"x.31" each) and the thermocouple using just a little more than 2cc. I let it dry at room temperature overnight, then carefully heated the hot plate up to 90 degrees C. I noticed a small amount of what looked like water vapor briefly coming from the ends of the cartridges. After ten minutes, I gradually ramped the hot plate up to 360 degrees C, with no problems at all.

## Questions & Answers

**Q: How can this not be electrically conductive but have water in it as another answer that was given, the 2 contradict each other?**
A: That's a great question! Once the Boron Nitride Paste has been heated to 100 °C, the water evaporates and all that is left is the paste. Usually, computer components do not reach this high of a temperature, so the water inside the initial mixture will not evaporate.

**Q: Is this more of an 'adhesive' by chance? i'm looking for a tidier way to keep water cooling blocks on my nema-17 steppers in 80c air, and love bn .**
A: Once the Boron Nitride Paste is dried, it is hardened which makes it act as a weak adhesive. It would probably not be the best idea to use it to keep water cooling blocks attached to a stepper motor.

**Q: Can this be used as cpu thermal paste? if not, why not?**
A: It is not recommended to use our Boron Nitride Paste as CPU thermal paste as our Boron Nitride Paste contains water. A proper thermal grease would be a better option for this use case.

**Q: I need a thermal paste to connect a thermostat cutoff switch to the outside of an oil heating (500 deg F) popcorn kettle.  Will this work?**
A: Slice Engineering Boron Nitride Paste is a thermal paste for improving conduction. We do not recommend that it be used as an adhesive.

### ⭐⭐⭐⭐⭐ Let it dry!!! It's a great paste for thermal transfer but you need to let it dry out before use!
*by S***R on July 7, 2024*

*** Slice Engineering states (on their website) that the paste needs to dry out. You can either, let it sit overnight or run the hotend at 90c for 10 minutes. This is because the paste contains water: to aid in squeezing it out of the syringe and spreading it effectively. If you don't let the water evaporate/dry from the paste, you can experience the ~bubbling that others complain about: this is the water boiling away at high temps and pushing the paste out of place. *** **Be cautious: the paste can push out of the tube with excess (upon first use, after it has sat for a long period). I would suggest trying to pull the syringe back a bit: before pushing forward. ** Overall the performance of this Boron Nitride paste is exceptional compared to other general use thermal pastes, for 3D printing. I've got a P1S, running a V2 Aftermarket hotend w/ .4 CHT Bondtech Nozzle: getting ~30mm^3/sec. This paste really helps when you need to dissipate heat between the "cold-end"/Thermal tube: of the hot-end assembly, and the heat-sink; I also put a small amount on the threads of the nozzle. { Use caution to try to not let much of the paste get into the filament path. I didn't run into issues, even having done so. You can always use water to clean off excess paste: Iso worked well for me too. } I did run into temporary issues: getting thermal malfunction errors, because I didn't realize the paste needs to dry. ( It's also likely I didn't apply enough paste into the thermister hole nor push the bulb into the hole far enough: to get good/consistent readings.) Once you are aware of these several, obscure aspects of how to use the paste: properly, things work out great. Well worth the money, for what you get. I would recommend it for anyone seeking to improve their 3D printing experience.
