Sparc announced today that after six months of testing, its graphene-based additives was found to offer up to 40% improvement in the anti-corrosive performance of atmospheric epoxy coatings. The company used commercially available epoxy coatings available from leading coatings manufacturers.
Kemind's graphene-enhanced glue enables a 30-50% increase in its corrugated board production process
Italy-based Kemind Srl developed new graphene-enhanced glue concepts, that have been applied to its corrugating production process. It is reported that the new glue increases production efficiency, reduces costs and improves quality for several of Kemind's corrugated board products.
Kemind is using 2DFab's graphene, and the company reports that it is possible to achieve an increase of between 30-50% in the double and triple walled heavy grades production, while energy and glue consumption in single and double walled board grades can be reduced substantially.
Greece-based industrial paint producer Hydroton has launched a new graphene-enhanced zinc epoxy paint - the 23303 ZINCTON GNC. This is a two-component epoxy based coating that offers improved cathodic protection due to the addition of the graphene, compared to epoxy zinc rich primers.
The new primer also offers improved adhesion to metal and as the zinc content is low, it is still cost effective. It is recommended for applications in highly corrosive environments.

The following is a sponsored post by Graphene Labs
Graphene nanoplatelets (GNPs), unique materials produced from natural graphite, are finding their way into a wide variety of commercial products including nanocomposites, lubricants, additives to battery electrodes, functional textiles, as well as many other applications.
GNPs have quite a few outstanding properties that allow them to be employed in a broad spectrum of applications, including:
- Superb mechanical strength
- Excellent electrical conductivity
- Ability to vastly improve the tensile strength and fracture toughness of polymers
- Low percolation threshold
- Resistance to corrosion
Norway-based CealTech was established in 2012 to commercialize a patented 3D graphene production method. The company recently received its first prototype proprietary industrial-scale Plasma-Enhanced Chemical Vapor Deposition (PE-CVD) graphene production reactor.
We discussed CealTech's technology and business with the company's marketing and sales manager, Michel Eid. Michael holds a Ph.D. in Solid Mechanics from the Ecole Polytechnique in France, and held various roles in engineeing, manufacturing, sustaining, sales, marketing and business development. Michel joined CealTech in January 2017.
Q: Hello Michael. CealTech is commercializing a patented 3D graphene production method. Can you give us some details on the process and the material you are producing?
Our production process is based on David Boyd’s technique as per Nature communications (DOI: 10.1038/ncomms7620), ‘Single-step deposition of high-mobility graphene at reduced temperatures’. In summary, the substrate is directly exposed to a low-pressure, microwave hydrogen plasma containing small amounts of methane as carbon source. During this process, vertical grown graphene flakes nucleate and arrange perpendicularly to the surface of the substrate forming a so-called 3D network of non-agglomerated graphene flakes.
