HydroGraph Launches Fractal Graphene Paste(TM), Eliminating a Key Barrier to Commercial Graphene Adoption

HydroGraph Launches Fractal Graphene Paste™, Eliminating a Key Barrier to Commercial Graphene Adoption New Pre-Dispersed, Stabilized Graphene Concentrate Enables Faster Integration into Water-Based Formulations AUSTIN, Texas, June 29, 2026 (GLOBE NEWSWIRE) -- HydroGraph Clean Power Inc. (CSE: HG) (OTCQB: HGRAF) (“HydroGraph” or the “Company”) today announced the commercial launch of Fractal Graphene Paste™ , a highly concentrated, pre-dispersed aqueous graphene product designed to simplify integration of graphene into industrial formulations and accelerate commercialization across multiple end markets. Fractal Graphene Paste™ delivers HydroGraph’s high-purity Fractal Graphene™ in a stable, ready-to-use dispersion, eliminating the need for customers to overcome one of the most significant technical challenges associated with graphene adoption: achieving effective dispersion. Graphene has long been recognized for its potential to improve material performance, but commercial implementation has often been hindered by processing complexity.

Graphene powders are naturally hydrophobic and tend to agglomerate when introduced into water-based systems, requiring specialized equipment, high-energy mixing, and extensive formulation work. Fractal Graphene Paste™ addresses these challenges by providing a fully dispersed, stabilized graphene concentrate that can be incorporated “off the shelf” using standard mixing equipment. “Dispersion is where many graphene projects succeed or fail,” said Kjirstin Breure, President and Chief Executive Officer of HydroGraph. “Fractal Graphene Paste™ allows customers to focus on product development and performance rather than overcoming processing challenges. By delivering a stable, high-concentration graphene dispersion that integrates directly into existing manufacturing processes, we are lowering barriers to adoption and accelerating commercialization opportunities across multiple industries.” Fractal Graphene Paste™ from HydroGraph contains 20% graphene by weight, making it one of the highest concentration graphene dispersions commercially available while remaining long-term stable.

Comparable commercial graphene dispersions are typically available at concentrations of only 1% to 5% graphene. HydroGraph’s proprietary stabilization technology, combined with the Company's ultrafine graphene morphology (D50 particle size of approximately 35 nanometres), maintains long-term dispersion stability and prevents re-agglomeration during storage and processing, with a greater than two-year shelf life. Dispersion quality and particle size distribution have been verified using Dynamic Light Scattering (DLS).

The product incorporates HydroGraph’s Fractal Graphene™, produced using the Company’s proprietary Hyperion Reactor technology, providing verified batch-to-batch consistency and carbon purity of 99.8%. Initial Market Applications Fractal Graphene Paste™ has been designed specifically for water-based systems and is being targeted toward several high-growth markets, including: Concrete and construction materials , where graphene can improve strength and durability while supporting reductions in embodied carbon. Protective and functional coatings , where graphene can enhance barrier performance, corrosion resistance, and service life.

Thermal management applications, including liquid cooling systems and thermal interface materials used in data centers and AI infrastructure. Elastomers and rubber compounds , where graphene can improve tensile strength, wear resistance, and durability. HydroGraph has already supplied Fractal Graphene Paste™ samples to more than 30 customers for evaluation across multiple application areas.

The Company currently has manufacturing capacity to support research, development, and early commercial production quantities, with production expected to scale alongside customer demand. “Customers increasingly want graphene products that can be implemented within existing manufacturing environments without significant process changes,” said Breure. “Fractal Graphene Paste™ reflects HydroGraph’s commitment to developing application-ready solutions that make advanced materials more accessible and commercially practical.” The launch expands HydroGraph’s growing product portfolio , which includes Fractal Graphene™ powder products and Reactive Graphene™ functionalized materials, enabling customers to select the format best suited to their manufacturing processes and application requirements. https://youtu.be/fnbhY2ejl8c Fractal Graphene™ Paste is available now.
