Graphene – The Future in Corrosion Technology
Graphene is an exciting and thoroughly 21st Century material. First isolated in 2004 at the University of Manchester, it has, in its purest form, a molecular structure comprising of a single layer of carbon atoms bonded in a hexagonal structure.
The graphene used in Blocksil corrosion-resistant coatings is manufactured by Applied Graphene Materials in the UK using a patented, synthetic, bottom-up process that is repeatable, proven and almost completely free of graphitic impurities, graphene oxide or transition metals.
Graphene possesses an unsurpassed combination of mechanical, electrical, and thermal properties. It has an extremely high aspect ratio, considerably higher than conventional additives such as MIO (micaceous iron oxide) or glass flake.
This presentation will demonstrate how graphene enhances corrosion resistance and coating adhesion. For example, in the ISO 9227:2017 neutral salt spray test, an astonishing 11,800 hours was achieved, while the addition of graphene improves coating adhesion after 5,000 hours by 45 per cent over a more conventional coating.
Blocksil’s main graphene enhanced Blocksil coating has been successfully fire tested and the company is currently working on adding graphene into other coatings and paints, such as two-pack primers and an aerosol applied industrial etch primer.
Finally, the presentation will show graphene enhanced coatings in use and explain the benefits of Blocksil coatings.
At the exhibition, more information can be found on the Blocksil stand – N18 in hall 11.
