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.

Hydroton launches a graphene-enhanced anti-corrosion primer

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.

G6-Epoxy: A New Generation of Graphene-Enhanced Electrically Conductive Adhesives Offers Competitive Advantages

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.

G6 Epoxy (G6E RTC)

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

CealTech's marketing and sales manager explains the company's technology and business

Michel Eid (CealTeach)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.

Graphene-enhanced anti-corrosion system deployed in bridges and wind power towers across China

China-based The Sixth Element Materials launched its graphene-zinc anti-corrosion primer back in 2015 together with his partner Toppen Technology, and the company has since performed extensive testing. TSE updates us that the material has now been deployed in China and has been used to cover several bridges and wind-turbines steel towers.

Anti-corrosion 2k-graphene-epoxy coating in China (TSE)

The Sixth Element graphene type SE1132 is added to Toppens 2k-epoxy primer system. TSE says that by adding 1% of graphene, one could reduce the zinc content in current anti-corrosion coatings from ~80% to 25%, and the the corrosion protection time is doubled. Reducing the zinc also means that this solution is less polluting. The main cost savings comes from the prolonged coating life which means that the time between coating renewal (which requires a lot of labor) is doubled.
