Scientists have reported a self-healing epoxy-silane graphene oxide coating that maintained strong corrosion resistance in saltwater testing and recovered protective performance after scratches, a result that could matter for industrial assets exposed to harsh environments.
Sparc Technologies and HydroGraph have signed a letter of intent to test HydroGraph’s Fractal Graphene in solvent-based protective coatings, after earlier water-based trials showed positive performance benefits. The move opens a path to a definitive commercial supply agreement if ISO 12944 corrosion testing delivers the expected results.
HydroGraph Clean Power and Sparc Technologies have signed a letter of intent to test graphene-enhanced protective coatings for steel infrastructure, a step that pushes the material closer to commercial use in harsh industrial environments. The companies say they will conduct longer corrosion trials before deciding whether to negotiate a definitive supply deal.
Graphene Manufacturing Group has accepted the U.S. Environmental Protection Agency’s consent notice conditions for THERMAL-XR ENHANCE, a graphene coating designed for HVAC systems, clearing a key regulatory hurdle for commercial sales in the United States.
Sparc Technologies says its ecosparc graphene additive is now being produced at a fully commissioned facility in Australia, giving the company commercial quantities for coatings trials and near-term customer opportunities. The milestone is a practical step toward broader industrial use of graphene-based anti-corrosion coatings.
A Scientific Reports paper published April 11 describes a two-step superhydrophobic coating for steel that reported 96.5% corrosion protection, 161-degree water contact angle and durability after 1,100 mm of abrasion.
