AGM has received the UK Patent No. GB2585648 for Graphene Nanoplatelets in water-based anti-corrosion protective coatings.
Applied Graphene Materials, a manufacturer of specialty graphene nanoplatelet dispersions, as recently announced the issuance of the UK Patent No. GB2585648, that covers the use of Graphene Nanoplatelets in water-based anti-corrosion protective coatings applications.
Graphene nanoplatelets are employed to provide highly effective barrier properties, enhancing corrosion prevention in solvent-based paints through the use of high-performance dispersions. The introduction of Graphene nanoplatelets into water-based paints used to problematic because of the challenges in producing effective and stable dispersions for water-based systems.
AGM’s range of water-based dispersions has now an officially recognised patent that demonstrates its ability to enhance corrosion performance in these systems. The company’s dispersions enable primer systems to achieve ISO 12944 category C3 or C4 corrosion rating performance for environments that include urban and industrial atmospheres, moderate sulphur dioxide pollution or coastal areas with low to moderate salinity.
“The global cost of corrosion is substantial and there is significant and growing pressure within the international coatings industry to reduce and ultimately remove the dependence on harmful volatile organic compounds (VOCs). The move towards a water-based technology solution is a primary goal for many protective coatings innovators,” stated Adrian Potts, Chief Executive Officer at AGM. “Overcoming the challenge of dispersing graphene nanoplatelets into such coatings has been a significant area of development for AGM’s technical team, and I am pleased that this technology has resulted in patent coverage. This latest dispersed product technology offers the coatings industry a new tool in the formulation of water-based systems. It provides a further opportunity to narrow the gap in solvent and water-based coating performance by enabling the use of graphene nanoplatelet materials thereby supporting the move away from solvent-based products.”
