GMG Launches New Graphene Water Coolant Additive for Data Centres: G FLUID(TM)

Queensland, Australia--(Newsfile Corp. - August 24, 2026) - Graphene Manufacturing Group Ltd. (TSXV: GMG) (OTCQX: GMGMF) (" GMG " or the " Company ") is pleased to announce the launch of patent pending G FLUID TM for use as a graphene water-based additive for data centre and industrial cooling circuits to increase heat transfer and reduce microbial and bacterial growth. The cooling water treatment chemicals market is valued at US$15 billion per annum in 2026 and is expected to be valued at US$27.2 billion per annum in 2035 (with a 6.1% CAGR). The G FLUID TM product can be used in various application. G FLUID TM is expected to provide a higher heat transfer rate for data centre and industrial cooling systems - with preliminary internal testing showing an increased heat transfer rate of approximately 20% when G FLUID TM is dosed into demineralized water at 1% - providing 0.01% of graphene by weight in final solution. G FLUID TM provides up to 87% anti-microbial testing outcomes as tested by an independent third party laboratory under testing standard EN 1276. GMG's Managing Director and CEO, Craig Nicol, commented: " G FLUID TM lets a data centre, industrial plant or building operator improve the heat transfer of the water or coolant already running through their cooling loop, at a simple 1% dose rate. Independent laboratory testing to the EN 1276 standard also shows a meaningful reduction in microbial growth in that same water, which matters for anyone managing corrosion, fouling and maintenance costs in a chiller system. We're launching first into data centres, where cooling demand is growing fastest, but the same dosage works in industrial process chillers and building chiller systems, giving us a large market to grow into." GMG's Chairman and Director, Jack Perkowski, commented: " G FLUID TM is our fourth energy-saving product alongside THERMAL-XR® and G® LUBRICANT, and it gives GMG a foothold in a cooling water treatment market worth more than US$15 billion a year globally, growing quickly as AI-driven data centre construction accelerates. It's a strong example of how our graphene production capability keeps opening up new, commercially relevant applications across very different industries." USA EPA Application Update: GMG is also pleased to announce the Company has submitted an amendment application to the United States Environmental Protection Agency ("EPA") seeking approval to manufacture, in addition to sell, graphene and GMG's THERMAL-XR®, G® LUBRICANT and G®FLUID products in the United States. This was based on the advice from the EPA to replace the Significant New Use Notice ("SNUN") the Company submitted in June 202...
