Check the listing for details. Boron nitride, high temperature resistant paste, mold release, 50 gr., Ukraine. Condition: New. Listed at 23.00 USD. Boron nitride, high temperature resistant, thermal paste Packaging: 50 gr., custom packaging. Content: wurtzite boron nitiride powder (10/7 micron), 40% in water/alcohol soluble composition. Properties: high thermal resistance and conductivity, dielectric strength (eliminates the risk of shorting out).Application: - mold release;- detaching and protective for high temperatures (up to 2000 °C), accelerates dismantling of connections operating at high temperatures, anti-stick coating;- thermal conductor, including for more effective heat distribution in 3-d printers' hot blocks, reducing clogs and making removing nozzles easier;- facilitates cutting of hard materials, extends the service life of cutting tools, provides a lower operating temperature. How it works: apply uniform layer; composition will evaporate under high temperature, leaving boron nitride on the surface; to some extent it's also stress resistant. On the first heating there is a mild burning plastic smell, which is the glycating agent evaporating, so for first indoor use ventilation is needed. If smell is an issue, buy wurtzite boron nitride powder and make water mixture (1:1 by weight). Directions of use: - General: apply uniform layer to the surface and let it dry; - 3 d printer cartridges (thermistor & heater) and heat breaks: coat the surface, install while the paste is still wet and let it dry before heating up;- Nozzles: apply small amount to threads of the nozzle (do not apply the paste to the threads of the heater block), install the nozzle while the paste is still wet and let it dry before heating. This boron nitride thermal paste may dry up; just add some water and stir well. Why it's better: - Thermal expansion of wurtzite boron nitride (according to Ioffe Institure) is approx. 1.5 lower than that of hexagonal boron nitride (in competing solutions) and consequently of other materials. Which means higher stability of coating layer under high temperatures. - Thermal conductivities of wurtzite crystal, parallel and perpendicular to the axis, are identical. Which means higher stability of thermal properties in comparison to hexagonal boron nitride. The same paste, packaged in 150 gr.
