WURTZENITE™ BORON NITRIDE, HIGH TEMPERATURE RESISTANT COATING


 
Net weight: 50  gr.
 
Content: wurtzite boron nitride powder (10/7 micron) in aqueous alkaline solution of silicates.  

Product Оptions:
1. Compound: paste that needs to be applied with a spatula. Creates a relatively thick layer of coating. Weight per 1 sq. m - 600-900 gr.
2. Emulsion: liquid composition that can be sprayed onto a surface. Layer of coating is thinner. Weight per 1 sq. m - 300 gr.


Properties of boron nitride thermal coating:
- High temperature resistance and conductivity, dielectric strength (eliminates the risk of shorting out). 
- Thermal conductivity  2.7 watt/centimeter/°C
(Thermal conductivity of  wurtzite boron nitride powder- 7.4 watt/centimeter/°C compared to silver with 4.29 watt/centimeter/°C)
- Dielectric constant - 5
- Dielectric loss tangent- 2 * 104 tgδ, 1 MHz
   
Application:
- Detaching (dismantling) and protective for high temperatures (up to 2000 °C);
- Anti-stick coating,
- Radio-transparent coating, etc.
  
How it works: composition of silicates and wurtzite boron nitride hardens on surface under high temperature and leaves stress resistant coating, see the video below: 

Silicate-based boron nitride coating on a graphite electrode after heating at 800C for 10 minutes. The coating hardens and remains on the surface after mechanical impact. 

Compound	Emulsion

Directions of use: apply uniform layer to the surface and let it dry for 1-2 hours, depending on temperature.  
Once opened, use within 7 days or store in tightly closed bottle. 

 Advantages: 
- Thermal expansion of wurtzite boron nitride (according to Ioffe Institute) is approx. 1.5 lower than that of hexagonal boron nitride and other heat resistant materials. Which means higher stability of coating layer under high temperatures (<2000 °C = 3632 °F);
-  Thermal conductivities of wurtzite crystal, parallel and perpendicular to the axis, are identical. Which means higher stability of thermal properties in comparison to other heat resistant materials, including such forms of boron nitride as hexagonal and cubic. 

Avoid contact with eyes and skin. In case of contact with eyes or skin - rinse with water

WURTZENITE™ BORON NITRIDE, HIGH TEMPERATURE RESISTANT PASTE 


 
Net weight: 50, 150, 500, 1000 gr.
 
Content: wurtzite boron nitride powder (10/7 micron), 40% in water/alcohol soluble composition.

Properties: boron nitride thermal paste, high temperature resistance and conductivity, dielectric strength (eliminates the risk of shorting out) 
Thermal conductivity  2.7 watt/centimeter/°C
(Thermal conductivity of  wurtzite boron nitride powder- 7.4 watt/centimeter/°C compared to silver with 4.29 watt/centimeter/°C)

Grain size:  10/7 micron  (see particle  size distribution diagram of wurtzite boron nitride powder)
  
Application:
- mold release;
- detaching (dismantling) and protective for high temperatures (up to 2000 °C);
- 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: composition  evaporates under high temperature, leaving boron nitride on the surface, which, to some extent, is also stress resistant. On the first heating of wet surface, there is a mild burning plastic smell, which is the glycating agent evaporating, so for first indoor use ventilation is needed  or let paste dry. 
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.

The finest grain size is 0.5/0 micron (fine polishing), but we can make 0.25/0 and 0.1/0 micron. 

 We replaced spray bottles (second photo) with dropper bottles (main photo),
as the dropper is more convenient (according to customer reviews) and does not clog.
Sprayer bottles are still available, please tell me if you need them. 

This emulsion shows excellent non-drying(delayed drying) properties:
- Unlike other common water-based products on the market that dry out easily, this emulsion is very suitable for lapping as it can be used for a long time without particle clog and fixation(less impregnation) due to fast drying.
- It works really well on strop media that is harder than leather, like copper(half impregnation/half loose), cast iron, granite, CGSW hard strop.
- Excellent deburr properties in loose abrasive's rolling abrasion mode.

Why it's important:
As you know, once you apply diamond/CBN to leather, it will work almost forever. However, for non-absorbent surfaces, most emulsions will lose most of its abrasiveness when washed out -> frequent reapply required = higher consumption and higher costs.

Shake it well before use
Coarse grains (> 5/3 micron) are heavier, so shake it even better,
if you still see residue on the bottom - It wouldn't hurt to stir it with thin stick.
