Carbodeon’s portfolio of nanodiamond materials

uDiamond® materials bring diamond performance to industrial applications. Diamond possesses extreme material properties including hardness and thermal conductivity. These 4 to 6 nm spherical diamonds are also electrically non-conductive and virtually transparent when incorporated in other materials. Our nanodiamond materials have specific surface functionalization and dispersion properties for use as a modifier in countless other materials. The current product offering includes both carboxylic acid, hydrogen and amine-terminated detonation nanodiamond powders as well as their aqueous and polar organic solvent dispersions. The particles mono-functionalized surface allows optimized affinity towards parent materials and reaching the sought improvements with minimum material additions. Said improvements will either allow significant cost savings via component improved service life or can be purely enabling and allow development of cutting edge end products.

Selecting the correct uDiamond® material(s) will depend on your application, and we always recommend contacting us to discuss your requirements. If your interest is within metal finishing, Carbodeon offers tailored nanodiamond additives for Electroless Nickel plating as well as Hard Chrome plating, both coming with their own application data sheets.

Metal Finishing

uDiamond® Electroless Nickel Composite Coating

Carbodeon patented uDiamond® Electroless Nickel Composite Coating is designed to reach abrasion resistance of hard chrome but at the same retain electroless nickel superior corrosion resistance, conformity as well as tribological properties. It is well suited for

enhancing electroless nickel coated components service life but especially suitable for replacing hard chrome where the coated component is suffering from erosion, the combination of simultaneous corrosion and abrasive wear. Such conditions are especially typical within Oil & Gas production wherein the producers can save significantly in downtime, part replacement and coating manufacturing costs.

The technology is also applied for producing ternary Electroless Nickel coatings together with either PTFE or h-BN particles.

Easy to implement to existing processes

The technology requires very little changes to existing Electroless Nickel plating lines and has proven to be cost efficient and stable. The application tailored uDiamond® Plating additive for Electroless Nickel is applied at 200 ppm concentration and replenished as consumed. The process stability can be controlled and maintained so that the normal number of plating cycles/ MTOs are achieved.

The technology allows further improvements in Hard Chrome already excellent wear resistance and that at affordable cost. Typical applications are in high performance components, such as Oil & Gas production components, engine and machine parts, agricultural & textile components, molds and military products.

Also uDiamond® Hard Chrome Composite Coatings are now available for sampling and small scale services, in UK. The interested parties should contact info@carbodeon.com.

CVD Seeding

Seeding materials for providing dense and nano-smooth CVD diamond coatings and CVD produced diamond objects. The typical industrial applications include but are not limited to various drill bits and cutting tools, allowing processing of thermally sensitive and/or easily cracking materials with highest precision and speed.

Chemical Vapor Deposition (CVD) seeding is a rapidly growing application for nanodiamonds. Carbodeon uDiamond® aqueous dispersions comprised of 4-6 nm mono-functionalized primary particles are applied by for example immersion or spin coating followed by a drying process. Selecting the right dispersion grade is dependent on component surface charge and great adhesion of the particles is achieved by selecting a dispersion comprised of oppositely charged particles. If for depositing for example on carbides, the right choice is our highly positively charged uDiamond® Hydrogen D aqueous dispersion product.

Our materials significantly outperform other forms of diamond seeding materials including powders or dispersions from our competitors and have been mentioned as the best seeding materials available at the market.

Polymer Thermal Compounds

Our nanodiamond additives are advantageously applied in a range of polymer thermal compounds applied within for example electronics, batteries and EV industries as whole. The target compounds can be thermosets such as epoxides, silicones and non-

silicone based thermal greases utilized as primary heat sinks. The target compounds can also be thermoplastic based materials utilized as secondary heat sinks.

THERMAL CONDUCTIVITY

Nanodiamonds exhibit thermal conductivity of 2000 W/mK, the highest available value for any dielectric material. Our particles highly active surface allows maximum coupling with both the compound other filler materials and the applied parent polymer. Optimized coupling minimizes the phonon scattering and maximizes the compound thermal performance allowing also breaking the boundaries not available with traditional thermal fillers. The typically applied nanodiamond loadings vary between 0.03 wt.% to 0.1 wt.% making the solutions also affordable.

COMPOUND WEIGHT AND MECHANICAL PROPERTIES

Higher thermal conductivity compounds mineral filler loading can be exceeding 90 wt.%, making said compounds both heavy and mechanically weak. The addition of our nanodiamond fillers can aid reducing the overall filler loading whilst retaining the compound thermal performance at the specified level. As a result the compound overall weight is reduced and its mechanical properties are improved.

Carbodeon co-development model

Most of the Carbodeon customer applications are tailored and solution specific. We realize every customer compound differs both in its composition and target performance. We are thus welcoming you to discuss both the best nanodiamond grade and it’s addition specific for your application.

Polymer Coatings

Our uDiamond® additives are applied to improve the service life industrial polymer coatings, the improvement resulting from our unique particles capacity to dispersion strengthen the cured polymer structure. Whilst dispersion strengthening is

typically resulting in coating enhanced wear resistance, also coating friction, thermal and optical properties can be altered.

INDUSTRIAL PTFE COATINGS

Carbodeon has developed a specific Nanodiamond additive for solvent based PTFE resins, improving said coating abrasive wear resistance by 100% with as low as 0.05 wt.% Nanodiamond loading. Also coating friction properties are further enhanced from its originally remarkable levels. In certain industries said further reduced friction allows manufacturing of lubricant-free end products.

Making the world a greener place has also resulted in development of environmentally more benign aqueous PTFE resins. Carbodeon has created an alternative product range to improve also these coatings service life.

OPTICAL TOP COATS

Our particles small size (4-6 nm) and their availability as primary particle based dispersions can allow our products use to improve optical top coats wear resistance, without impairing said coating optical properties.

HIGH REFRACTIVE INDEX COATINGS

Just like their bigger peers also nanodiamond exhibit refractive index over 2,3. When able to apply without any agglomeration, significant raises in coating refractive index are available.

Carbodeon co-development model

We work closely with our customers to ensure the product achieves the targeted improvements. Nanodiamond material may be added to coating formulations using one of our specific uDiamond® coatings additives, nanodiamond liquid dispersions or in a few cases also functionalized nanodiamond powders.

Mechanical Compounds

Our nanodiamond additives facilitate dispersion strengthening of virtually any thermoplastic material, with improved mechanical and thermal properties as follows. In industrial areas such as EV both the compound thermomechanical and reduced weight may be targeted.

3D PRINTING

The technology is also advantageously used in 3D printing filament development. Here, the filament improved thermal properties may facilitate faster printing with excellent layer to layer adhesion, or in some cases making the high-melting polymers such as PEEK printable in the in the first place. The printed item exhibits both thermal and mechanical improvements typically manifesting as dramatically improved HDT B values.

Chemical Mechanical Polishing (CMP)

Being spherical diamonds sizing 4-6 nm our Nanodiamond additives can be advantageously used in polishing slurries intended for ultra-fine polishing processes. Our product portfolio also allows finding the best suitable particles regardless the applied pH conditions.
