Brisbane, Queensland, Australia--(Newsfile Corp. - October 23, 2024) - Graphene Manufacturing Group Ltd. (TSXV: GMG) ("GMG" or the "Company") is pleased to provide a technical update on the commercialisation progress of THERMAL-XR® Powered by GMG Graphene.
PRODUCT TECHNICAL UPDATE
THERMAL-XR® has now successfully passed 15,000 hours for corrosion protection under a salt sea spray industry standard test (ASTM B117) in a third-party laboratory in the US as seen in Figure 1. 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 accurately model and calculate the heat transfer rate expected from THERMAL-XR®, as compared to bare (uncoated) Aluminium, within
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 that THERMAL-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 ft2 F (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 ft2 for bare aluminium.

Figure 4 shows THERMAL-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.
