Company Introduction
Thermal coating (boron nitride + solgel ceramics) Introductions

Combinations of sogel ceramics +boron nitride conducting excellent thermal performances sublimation point and good thermal shock stability,and physical characteristics -good electrical insulator, good heat conductivity and good high temperature lubrication qualities- make it an interesting ceramic material.


*Key Properties
Thanks to the binding nano size liquidied cramics(10-30um) for bn,
The High poly products possesses such outstanding characteristics as density of only 2.27 g/cu cm,a 2500c melting point, high chemical inertness and corrosion resistance, stability in air to 1000c,resistance to thermal shock, high electrical insulation value, and high thermal conductivity.

*Advantages :

1.High thermal conductivity Good thermal shock resistance
2.Excellent radiated heat transfer Chemically inert, corrosion and oxidizations
3.Low thermal resistivity and expansion Excellent lubrication properties with low coefficient in wide temperature
4.Low dielectric constant and loss tangent Withstand high temperature 2600c.
5.Increasing air/surface cooling areas Non-wetting surface protection layer coat



*Features and Benefits
High thermal conductivity of 100~250 W/mK
Low thermal resistance
Low dielectric constant and loss tangent
Excellent radiated heat transfer
Low dielectric constant


*Applications

Heat sinks
Turbo chargers
Heat exchangers
Furnaces
PCB boards
Power components
High power LED
High temperature components
Thermal modules
generator parts..
and more.

*APPLICATION INSTRUCTIONS
The popular application method is spraying and heat curing.
due to usage of liquidiezed ceramics, we need to cure the product with heat.
220c with 10mins will be the best way to cure the products. the ceramics combnations will provide better adhesions and thermal performances.

Surface Preparation
All surfaces should be clean and dry and free of any grease, oil, loose scale or particles and drawing compounds. If the surface is shiny and smooth, some surface roughening with a fine-grain sandpaper may be necessary. Typical material surfaces include metals, refractory ceramics, graphite, etc.

Coating Preparation
Shaking and stirring should be done until the coating is well suspended and uniform in texture. Coatings can be used straight from the container or thinned with water.

Spraying
For optimum results, some spray techniques should be followed.
1. Use standard spraying equipment / spray gun at approximately 50 psi.
2. At a distance of 25cm with 45 degree, use a continuous spray.
3. Coating should be applied in thin layers (approximately 15-30um)
4.deliver the coated products to heat chamber. heat up 200c-210c with 10mins.
5.take out them and cool down.
4.An ideal coating can be obtained by heating the substrate to 80c prior to spraying.
5. During multiple coatings adjust the spray angle and sweeping motion in order to cover all pores and surfaces. Make sure to start the gun facing away from the surfaces to be sprayed due to initial spurting.
Many guns will exhibit this tendency to fluctuate at start-up and will adversely affect your resulting surface.

Clean Up
Always clean air tools or brushes immediately in water after use. In some cases, our coatings can become hard to remove when cleaning is postponed. Special cleaning attention should be given to gun orifices, needles and hoses.
