Brisbane, Queensland, Australia - (October 23, 2024) -Graphene Manufacturing Group Ltd. (TSX-V: GMG) is pleased to provide a technical update on the commercialisation progress of THERMAL-XR®Powered by GMG Graphene.
PRODUCT TECHNICAL UPDATETHERMAL-XR® has now successfully passed15,000 hours for corrosion protectionunder a salt sea spray industry standard test (ASTM B117) in a third-party laboratory in the US. The Company believes that THERMAL-XR® is one of the longest lasting corrosion protection coatings available on the market. The testing will continue, and further reports will be updated by the Company.
GMG can now accuratelymodel and calculate the heat transfer rateexpected from THERMAL-XR®, as compared to bare (uncoated) Aluminium, within 1% of actual results. This was reviewed and verified by the University of Queensland.
Figure 2 shows the simulation model used to calculate the heat transfer coefficients of bare aluminium, versus THERMAL-XR® coated aluminium, on the test rig that GMG built and operated to obtain the experimental data. The test was conducted at a temperature of approximately 100 degree Celsius.

Through this work, as shown in Figure 3, the Company has demonstrated thatTHERMAL-XR® provides approximately 8.6 times more radiative heat transfer than bare aluminium, due to its thermal radiation (passing of heat in wave forms) capabilities. THERMAL-XR® has been calculated to provide 8.15 W/m2K (Watts per metre squared Kelvin degrees), or approximately 1.44 Btu/hr ft2F (British thermal units per hour foot squared Fahrenheit degrees), of heat transfer when applied properly on top of bare aluminium, as compared to 0.95 W/m2K or 0.17 Btu/hr ft2for bare aluminium.

Figure 4 showsTHERMAL-XR® increases the overall heat transfer coefficient by 2.2 times more than bare aluminium, from 6.0 W/m2K up to 13.2 W/m2K because of the increase in the thermal radiation from the THERMAL-XR® coating. This was conducted at a temperature of approximately 100 degree Celsius for a 100mm diameter flat plate.

Figure 5 shows thatTHERMAL-XR® provides approximately 27% more heat transfer when including FORCED convection (fan air cooling) over bare aluminiumfrom 26.6 W/m2K up to 33.8 W/m2K because of the increase in the thermal radiation from the THERMAL-XR® coating. This was conducted at a temperature of approximately 100 degree Celsius and with modelling of the air speed at an approximate 5 metres/second.

GMG's Managing Director and CEO Craig Nicol commented: "GMG continues to make good progress in testing THERMAL-XR® for corrosion protection and heat transfer - our increased understanding of the heat rejection rate of the product allows us to better recognise how it can be of potential value for various types of products in various applications and markets."
GMG's Chairman and Director Jack Perkowski commented: "THERMAL-XR® testing in corrosion protection and heat transfer is highly translatable into so many industries - so it is great to see the progress."
About THERMAL-XR®THERMAL-XR® COATING SYSTEM is a unique method of improving the heat conductivity of corroded heat exchange surfaces and improving and maintaining the performance of new units at peak levels. The process coats and protects heat exchange surfaces increasing service life, while improving and rebuilding the lost corroded thermal conductivity and increasing the heat transfer rate by leveraging the physics of GMG Graphene, resulting in an efficiency improvement and a potential power reduction. THERMAL-XR RESTORE® ispowered by GMG Graphene.PATENT PENDING
GMG is a clean-technology company which seeks to offer energy saving and energy storage solutions, enabled by graphene, including that manufactured in-house via a proprietary production process. GMG has developed a proprietary production process to decompose natural gas (i.e. methane) into its elements, carbon (as graphene), hydrogen and some residual hydrocarbon gases. This process produces high quality, low cost, scalable, 'tuneable' and low/no contaminant graphene suitable for use in clean-technology and other applications. See www.graphenemg.com.
The Company's present focus is to de-risk and develop commercial scale-up capabilities, and secure market applications. In the energy savings segment, GMG has focused on graphene enhanced heating, ventilation and air conditioning (HVAC-R) coating (or energy-saving coating), lubricants and fluids.
In the energy storage segment, GMG and the University of Queensland are working collaboratively with financial support from the Australian Government to progress R&D and commercialization of graphene aluminium-ion batteries ( G+AI Batteries ).
GMG's 4 critical business objectives are:
- Produce Graphene and improve/scale cell production processes
- Build Revenue from Energy Savings Products
- Develop Next-Generation Battery
- Develop Supply Chain, Partners & Project Execution Capability
