Sparc Technologies Revolutionizes Anti-Corrosion Solutions with Graphene Technology
Sparc Technologies (ASX: SPN) has announced groundbreaking results in its graphene-enhanced water-based coatings, demonstrating up to 60% corrosion reduction compared to commercially available products. This significant advancement positions the company at the forefront of the sustainable protective coatings market. Furthermore, the company's development approach mirrors strategies seen in other successful mining and resources companies where drilling near top producers has yielded promising results.
Game-Changing Corrosion Protection in Water-Based Coatings
Neutral salt spray testing conducted over periods of 480, 960, and 1,680 hours has confirmed substantial anti-corrosion benefits when incorporating low dosages of select graphene grades into commercial water-based epoxy coatings.
The testing, performed on two commercial products from a leading supplier, showed impressive results:
| Coating Type | Graphene Variant | Corrosion Reduction |
|---|---|---|
| Water-based Acrylic Epoxy | Graphene B | Up to 60% |
| Water-based Bis-A/F Epoxy | Graphene C | Up to 44% |
These results are particularly significant as the water-based coatings market experiences strong growth, driven by environmental concerns and regulatory pressure to reduce volatile organic compounds (VOCs).
"I am pleased with the very strong follow-on results from our initial testing in water-based coatings. The recent salt spray results demonstrate up to 60% anticorrosion performance improvement using Sparc's graphene-based additives within multiple commercial products which has the potential to unlock significant growth in this developing area of the protective coatings market," said Nick O'Loughlin, Sparc's Managing Director.
Expanding Market Opportunities in Sustainable Coatings
The company's advancement into water-based coatings represents a strategic expansion beyond its flagship ecosparc® product, which is primarily targeted at solvent-based coatings and currently undergoing field testing. This approach to diversification is similar to how some resource companies launch multi-target campaigns to maximise their potential for discovery.
Water-based epoxy coatings offer significant environmental advantages including:
- Non-toxicity
- Low odour
- Reduced VOCs (volatile organic compounds)
- Easier application and cleanup
These qualities make them increasingly attractive alternatives to traditional solvent-based products that contain fossil fuel-derived organic solvents. However, water-based coatings have historically suffered from performance limitations—a challenge that Sparc Technologies graphene coatings are now addressing directly.
The global market for water-based epoxy coatings is projected to grow from $1.6 billion in 2022 to $2.9 billion by 2029, representing a compound annual growth rate of 8.9%. This segment sits within the broader anti-corrosion coatings market, estimated to reach $43 billion by 2029.
Understanding Graphene's Corrosion-Fighting Properties
Graphene, a single layer of carbon atoms arranged in a two-dimensional honeycomb lattice, provides exceptional barrier properties that significantly enhance coating performance. When incorporated into protective coatings, graphene creates a physical barrier that prevents corrosive elements from reaching the underlying metal surface.
The material's unique properties include:
- Impermeability to most gases and liquids
- Exceptional mechanical strength
- Ability to maintain effectiveness at extremely low concentrations
- Compatibility with existing coating systems
These attributes make graphene particularly valuable as an additive in protective coatings, where even small dosages can deliver substantial performance improvements, similar to how high-grade antimony can significantly enhance the value of mineral deposits.
How Graphene Enhances Protective Coatings
Sparc Technologies graphene coatings work by incorporating carefully selected graphene variants at low dosage rates into existing coating formulations. The graphene particles distribute throughout the coating, creating a tortuous path that significantly slows the diffusion of corrosive elements like oxygen, water, and chloride ions.
The process of corrosion typically begins when these elements penetrate a coating and reach the metal substrate. By effectively blocking this penetration, graphene-enhanced coatings substantially extend the protective lifetime of the coating system.
What makes Sparc's approach particularly valuable is that it achieves these performance improvements without requiring coating manufacturers to completely reformulate their products. Instead, the graphene additives can be incorporated into existing coating systems, allowing for relatively straightforward adoption by industry partners.
Commercial Pathway and Market Potential
Sparc is pursuing a dual-track commercialisation strategy for its ecosparc® graphene-based additive:
-
Engaging with major coating manufacturers: The company is actively working with five of the eight largest global protective coatings companies.
-
Partnering with large asset owners: Collaborations are underway with government entities, oil & gas companies, and mining operations for field trials and confidential testing programs.
With field trial results and laboratory testing in commercially applicable products progressing through 2025, Sparc anticipates commercial acceptance and adoption of ecosparc®-enhanced products during FY26. The company has already established commercial manufacturing capability to support product volume scale-up, much like how vital metals secured funding to advance their strategic projects.
The target addressable market for ecosparc® within the broader anticorrosive protective coatings market is estimated at approximately $1.0 billion per annum.
"These results have been achieved leveraging Sparc's proprietary knowledge and expertise working with graphene-based additives in the significantly larger solvent-based anticorrosion market and are allowing us to broaden customer engagement and value-add as we approach commercialisation," noted O'Loughlin.
