Sparc Technologies Ltd (ASX:SPN) shares climbed 9.09% to AUD 0.18 on 24 March 2026, extending gains of 28.57% over the past six months. The upward move follows the company’s announcement of a new collaboration aimed at advancing its graphene-enhanced coatings technology.

Collaboration Targets Graphene-Enhanced Coatings

Sparc confirmed it has entered into a Letter of Intent with HydroGraph Clean Power Inc. to evaluate the use of HydroGraph’s Fractal Graphene within its ecosparc additive range for protective coatings.

The agreement establishes a framework for testing and potential future commercialisation, as both companies explore performance enhancements in coating applications.

Building on Encouraging Early Results

The collaboration follows earlier testing where incorporation of graphene into water-based coating systems demonstrated positive performance outcomes.

Under the new agreement, Sparc will expand testing into solvent-based coatings, including rigorous corrosion assessments aligned with international standards.

Pathway to Commercial Agreement

Subject to successful testing results, the parties intend to negotiate a definitive supply and collaboration agreement within approximately 12 months.

The current arrangement outlines responsibilities around testing, data use, and intellectual property, while also setting the stage for potential long-term commercial engagement.

Supporting Coatings Performance and Longevity

Sparc’s ecosparc additives are designed to enhance the durability and effectiveness of protective coatings, particularly in reducing corrosion and extending maintenance cycles for steel infrastructure.

The integration of graphene is expected to further improve performance characteristics, supporting applications across industries such as infrastructure, mining, and energy.

Advancing Commercialisation Momentum

The announcement comes after Sparc reported its first ecosparc revenue in December 2025, with the company indicating expectations for further commercial milestones in the first half of 2026.

Ongoing engagement with global coatings companies and field trials across various environments continue to support its broader commercialisation strategy.

What This Means for Investors?

Sparc’s latest update highlights continued progress in advancing its graphene-based coatings technology through strategic collaboration. The agreement, combined with prior testing success and ongoing commercial efforts, appears to have supported today’s share price gains as investors respond to the company’s development and partnership momentum.
