Sparc Targets US$1 Billion Market with HydroGraph Graphene Collaboration
Sparc Technologies has formalised a collaboration with HydroGraph Clean Power to test and potentially commercialise graphene-enhanced additives for protective coatings, aiming to revolutionise corrosion protection.
- Letter of Intent signed to evaluate HydroGraph’s Fractal Graphene in Sparc’s ecosparc additives
- Positive initial water-based coating tests pave way for rigorous solvent-based testing
- ISO 12944 corrosion testing scheduled, results expected by December 2026
- Potential commercial supply and collaboration agreement targeted within 12 months
- ecosparc targets a US$1 billion addressable market in anticorrosive coatings
A Strategic Collaboration in Graphene-Enhanced Coatings
In a move that could reshape the protective coatings industry, Sparc Technologies Limited (ASX:SPN) has entered into a Letter of Intent (LOI) with HydroGraph Clean Power Inc., a leading North American graphene producer. The partnership aims to integrate HydroGraph’s high-purity Fractal Graphene into Sparc’s ecosparc® additives, designed to enhance the performance of protective coatings used on steel infrastructure.
Following promising initial tests with water-based coatings, Sparc will now undertake more stringent ISO 12944 cyclic corrosion testing on solvent-based coatings. This internationally recognised standard assesses the durability and corrosion resistance of protective coatings, a critical benchmark for industrial applications. The results, expected by December 2026, will determine whether the collaboration advances to a definitive commercial supply and partnership agreement.
Unlocking Performance and Sustainability Benefits
ecosparc® additives have been under development for over six years, with Sparc reporting substantial improvements in corrosion protection and coating longevity at low graphene dosages. The integration of HydroGraph’s graphene is anticipated to further enhance these benefits, potentially extending maintenance intervals and reducing environmental impact through lower emissions associated with corrosion-related repairs.
HydroGraph’s CEO Kjirstin Breure highlighted the opportunity to demonstrate graphene’s value in established coating formulations, noting the significant return on investment for asset owners through extended asset life and sustainability gains. Sparc’s Managing Director Nick O’Loughlin emphasised the strategic advantage of partnering with a high-quality North American graphene supplier as ecosparc® moves towards broader commercialisation.
Market Potential and Next Steps
The global protective and marine coatings market is valued at approximately US$33 billion, with Sparc estimating a target addressable market of around US$1 billion for ecosparc® additives within anticorrosive coatings. Multiple global coatings companies are currently evaluating ecosparc® products, and Sparc is actively conducting field trials with key infrastructure sectors including government, defence, mining, and oil and gas.
The LOI formalises the framework for upcoming solvent-based testing and sets the stage for negotiating commercial terms, including graphene supply and product marketing. The collaboration’s success hinges on the forthcoming ISO 12944 test outcomes, with a definitive agreement expected within the next 12 months if results meet expectations.
As Sparc anticipates further commercial milestones in the first half of 2026, this partnership underscores the growing momentum behind graphene-enhanced materials in industrial applications, blending innovation with sustainability imperatives.
Bottom Line?
The upcoming test results will be pivotal in determining whether graphene-enhanced coatings can deliver on their promise to transform corrosion protection and sustainability in heavy industries.
Questions in the middle?
- Will the solvent-based ISO 12944 testing confirm the performance gains seen in water-based coatings?
- What commercial terms and supply volumes will define the definitive agreement between Sparc and HydroGraph?
- How quickly can ecosparc® additives penetrate the US$1 billion anticorrosive coatings market amid competitive pressures?
