Graphene plates
Later this month, Applied Graphene Materials UK Ltd (AGM; Redcar, Cleveland, U.K.; www.appliedgraphenematerials.com) will be presenting its “breakthrough” technology that enables easy graphene dispersion in water-based epoxy coatings, while delivering improved corrosion protection, at the Corrosion 21 Conference & Expo on April 28th (a virtual event; www.nacecorrosion.org). The technology is said to represent a major milestone in the development of performance-enhancing graphene technologies for more sustainable coatings manufacturers.
AGM has previously demonstrated significant uplifts in anticorrosion performance in solvent-based coatings through the use of its Genable graphene-nanoplatelet dispersion technology. However, water-based coating development remains a key focus for industry formulators looking to improve the safety and environmental impacts of their products.
To date, dispersion of graphene in water-based systems has been problematic, causing coating instability or requiring large amounts of surfactant. AGM’s technology enables easy dispersion of graphene in water-based epoxy coatings, while delivering improved corrosion protection — the research is said to represent an important development in raising waterborne coating anti-corrosion performance in industry applications.
