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.

 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.

WURTZENITE™ BORON NITRIDE, HIGH TEMPERATURE RESISTANT COATING

 
Net weight: 100, 500, 1000 gr., or custom packaging. 
 
Content: WBN (wurtzite boron nitride powder, grain size 10/7 micron) in heat resistant carrier (phosphates, aluminum oxide, sulphates).

Product format: water soluble paste; does not dry out under normal outdoor conditions.

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: carrier and wurtzite boron nitride hardens on the surface under high temperature and leaves a stress-resistant coating, see the video below.

Directions of use: apply uniform layer to the surface and let it dry.
- Under room temperature it dries approx. 24 hours, surface just should not be sticky. Heating to 150-200 degrees will speed up the drying. 
- The coating may be applied with a spatula. Creates a relatively thick coating layer. Weight per 1 m²: 600-900 g. 
- Add up to 20% of distilled (preferably) water by weight and stir well for using a spray gun. It is advisable to apply in several layers with a break between coatings of 2-3 hours at room temperature to let previous layer dry. Water should evaporate before use, or surface may "boil" when heated. 
Weight of layer per 1 m²: ~300 g.

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.

Boron nitride powder,  wurtzite crystal structure, w-BN. 

This  wurtzite boron nitride powder was manufactured by shock compression (explosion synthesis on military facility) of hexagonal boron nitride.  

Chemical composition of wurtzite boron nitride powder, % 

Grain size: 10/7 micron, see particle size distribution diagram

Application:  anti-stick coatings, dry lubricant, high temperature resistant additive, synthesis of superhard materials.
These powders may be added to plastics, potting compounds, oils, greases and other materials to provide enhanced thermal conductivity and dielectric strength. 

How to prepare  boron nitride anti-stick coating for protection of metals, glass, ceramics, composites, plastics and other materials. 

  Wurtzite boron nitride has a potential for manufacturing of advanced electronic devices, because such its properties as  as a wider band gap, higher thermal conductivity, and larger spontaneous polarization, are superior to Gallium nitride (GaN) and Aluminium nitride (AlN). 
Incorporation of a few percent of B in AlN and GaN is an important perspective in strain engineering and  developing deep UV emitters

According to Ioffe Institute, thermal expansion of wurtzite boron nitride is the lowest among other materials, so it ensures higher stability of coating layer under high temperatures. You can buy high temperature wurtzite boron nitride paste here.

DIAMOND EMULSION SPRAY, DIAMOND SUSPENSION, DIAMOND SLURRY
HIGH CONCENTRATION

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.

Preparation of sharpening stones
These stones require preparation (dressing), or they will be self-polished after sharpening of 30-50 knives. Then they will be of gold color and work well.
This is common issue for all manufacturers: abrasive grains are covered with bond, so you need to "release" them.

QUICK-DRYING
DIAMOND POLISHING, LAPPING PASTE,
CONCENTRATION TRIPLE EXTRA HIGH  

The Innovation: From Liquid Paste to a Premium Polishing Stone

1. Innovative Solidifying Bond: After drying, the paste creates a  waxy layer over your polisher or blade.
2. Diamond-Impregnated Matrix: This protective wax becomes heavily impregnated with diamond particles , locking them tightly in place.
3. Instant Sharpening Stone Transformation: This process effectively turns your leather strop, balsa wood, felt wheel, or metal lap into a high-performance polishing stone . This eliminates the mess of shifting paste, stops diamond particles from migrating, and provides a solid, uniform abrasive surface that mimics the precision of a diamond sharpening stone.

Why Choose Our  Triple Extra High Concentration Diamond Paste?

1. Lightning-Fast Drying Formula: Our advanced volatile carrier base evaporates quickly after application. This prevents the compound from spinning off, splattering, or running when used on high-speed polishing wheels or manual strops.
2. Maximum Diamond Density: With a Triple Extra High abrasive concentration, every drop is loaded with industrial-grade micro-diamonds. You need less product to get the job done, reducing polishing time and product consumption.
3. Precision Gradation & Uniform Particle Distribution: Available in multiple micron sizes for everything from aggressive stock removal to final optical-grade mirror polishing. Zero agglomeration ensures scratch-free, uniform finishes.
4. Easy Cleanup: Despite forming a durable waxy layer during use, the compound is formulated to wash away effortlessly using standard degreasers or warm soapy water, leaving no permanent residue behind.

Versatile Industrial & Workshop Applications

1. Knife Sharpening & Stropping: Perfect for loading leather, balsa wood, or composite strops. The hardened waxy layer creates a razor-sharp, mirror edge on premium tool steels (M390, CPM-20CV, D2) and tungsten carbide without rounding the apex. 
2. Gemstone & Jewelry Polishing: Provides exceptional clarity and brilliance on diamonds, sapphires, rubies, quartz, and precious metals.
3. Mold, Die & Tool Engineering: Ideal for precision lapping, final finishing of injection mold cavities, and eliminating tool marks on hardened steel surfaces.
4. Metallurgical & Optical Preparation: Trusted by labs for scratch-free specimen preparation and optical glass polishing.

Technical Specification

How to Achieve Best Results

1. Prepare the Surface: Ensure your workpiece is clean and free of debris from previous coarser grinding steps.
2. Apply Sparingly: Due to the heavy 3E concentration, a tiny bead is highly effective. Apply to your strop or polishing tool and spread evenly.
3. Allow to Set: Wait a few moments for the quick-drying carrier to stabilize and form the diamond-impregnated waxy stone layer .
4. Polish: Work the surface with uniform pressure. Clean the workpiece thoroughly before moving to a finer micron grade to prevent cross-contamination.
