The testing has reportedly demonstrated significant corrosion performance improvements through the incorporation of low dosages of carefully selected grades of graphene compared to an unmodified control. Testing has been performed using two industry-recognized electrochemical measurement techniques.
Water-based coatings are gaining prominence due to better environmental credentials compared to more widely used solvent-based coatings which contain fossil fuel derived organic solvents. These results are the first evidence that Sparc has seen whereby graphene significantly improves the corrosion performance of water-based coatings. This extends Sparc’s reach into a new and rapidly growing area of the coatings market where there are clear performance challenges to address. It also complements Sparc’s flagship ecosparc® product range.
Sparc Managing Director, Mr. Nick O’Loughlin commented: “There is an increasing push from the coatings industry towards more environmentally friendly water-based products, however their performance has not been adequate for wide scale industry adoption in corrosive applications. Our results clearly demonstrate a significant performance improvement with graphene which has the potential to unlock significant growth in this developing area of the coatings market. Pleasingly, these results have been achieved by leveraging Sparc’s proprietary knowledge and expertise working with graphene-based additives in the significantly larger solvent-based anticorrosion market and allows us to broaden our customer engagement.”
