Can Sparc’s Graphene Coatings Protect Iconic Lighthouse and Capture Market Share?

A Landmark Collaboration

Sparc Technologies (ASX, SPN) has announced a significant partnership with Dulux Australia to apply its flagship graphene-based additive, ecosparc®, within Dulux’s epoxy-based protective coating system on the Cape Jaffa Lighthouse. This project represents Sparc’s first collaboration with Dulux and its fifth real-world application alongside major coatings manufacturers, underscoring growing industry interest in graphene-enhanced materials.

The Cape Jaffa Lighthouse, a historic cast iron structure listed on the South Australian State Heritage Register, faces harsh coastal conditions that accelerate corrosion. The application of ecosparc®-enhanced coatings aims to demonstrate improved durability and corrosion resistance in this challenging environment, potentially extending the lifespan of critical infrastructure.

Strategic Commercialisation Moves

For Sparc, this trial is a crucial step in its broader commercialisation strategy targeting the US$33 billion global protective coatings market. The company has invested over six years in developing ecosparc®, which at low dosages significantly enhances the performance of epoxy-based coatings. With a commercial production facility already operational, Sparc is positioned to scale up supply as adoption grows.

Dulux’s involvement brings valuable industry expertise and rigorous R&D capabilities. According to Dulux’s Protective Coatings General Manager, Vin Brereton, this collaboration will provide real-world performance data critical for validating graphene’s value in corrosion protection, a challenge that has limited graphene’s broader adoption despite its promise.

Heritage Meets Innovation

The National Trust of South Australia, which manages the lighthouse, expressed strong support for the project, highlighting the importance of protecting this iconic piece of Australian history. The lighthouse’s relocation onshore in 1973 and its ongoing preservation make it an ideal showcase for innovative protective technologies that can safeguard heritage assets against environmental degradation.

Scheduled to take place over November and December 2025, the coatings application will be closely monitored. Sparc’s Managing Director, Nick O’Loughlin, will host an investor webinar on 12 November to update stakeholders on ecosparc®’s development and commercialisation progress, signaling transparency and engagement with the investment community.

Looking Ahead

While the trial’s outcomes remain to be seen, the collaboration with Dulux and the National Trust positions Sparc at the forefront of graphene-enhanced protective coatings. Success here could accelerate adoption across sectors such as mining, oil and gas, and infrastructure, where corrosion protection is critical. However, the company must still navigate market acceptance hurdles and demonstrate consistent performance advantages to convert this promising technology into sustained revenue growth.
