GMG’s Managing Director and CEO, Craig Nicol, commented: “Reaching more than 30,000 hours of ASTM B117-19 salt sea spray testing with no observed corrosion is a significant validation of THERMAL-XR® ENHANCE in one of the harshest standard corrosion test environments available. To put this in context, many premium automotive, building and industrial coatings are benchmarked at around 1,000 hours, and high-performance marine and offshore systems at 2,000 hours or more, with extended programmes for some advanced systems reaching into the low thousands of hours. By surpassing 30,000 hours in continuous salt spray testing while also delivering improved heat transfer under high air-flow conditions, THERMAL-XR® ENHANCE demonstrates truly next-generation performance in both corrosion protection and heat-exchange efficiency.”
GMG’s Chairman and Non-Executive Director, Jack Perkowski, commented: “It is fantastic to see THERMAL-XR® ENHANCE providing measurable benefits in such an important application – space cooling, refrigeration and data centres in demanding operating and environmental conditions. These results, combined with our growing regulatory approvals and distribution footprint, give us confidence in the role THERMAL-XR® can play as a global benchmark coating for energy savings and corrosion protection.”
About THERMAL-XR® ENHANCE powered by GMG Graphene:
THERMAL-XR® ENHANCE coating system is a unique method of improving the 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 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® ENHANCE is now patented for 20 years in Australia and is expected to be patented in other countries around the world.
About GMG:
GMG is an Australian based clean-technology company which develops, makes and sells energy saving and energy storage solutions, enabled by graphene manufactured via in house production process. GMG uses its own proprietary production process to decompose natural gas (i.e. methane) into its natural 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.
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 initially focused on graphene enhanced heating, ventilation and air conditioning (“HVAC-R”) coating (or energy-saving coating) which is now being marketed into other applications including electronic heat sinks, industrial process plants and data centres. Another product GMG has developed is the graphene lubricant additive focused on saving liquid fuels initially for diesel engines.
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 has also developed a graphene additive slurry that is aimed to improve the performance of lithium-ion 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

Cautionary Note Regarding Forward-Looking Statements
This news release includes certain statements and information that may constitute forward-looking information within the meaning of applicable Canadian securities laws. Forward-looking statements relate to future events or future performance and reflect the expectations or beliefs of management of the Company regarding future events. Generally, forward-looking statements and information can be identified by the use of forward-looking terminology such as “intends”, “expects”, “anticipates”, “plans”, “estimates” or “believes”, or variations of such words and phrases, or statements that certain actions, events or results “may”, “could”, “should”, “would” or will “potentially” or “likely” occur. These statements, referred to herein as “forward-looking statements”, are not historical facts and are made as of the date of this news release.
Forward-looking statements in this news release include, without limitation, statements regarding: the Company’s expectations relating to the performance, durability, energy savings and enhanced corrosion resistance of the THERMAL-XR® ENHANCE graphene coating product in commercial applications; the Company’s belief that THERMAL-XR® ENHANCE represents next-generation heat transfer technology and a global benchmark coating; the anticipated benefits of THERMAL-XR® ENHANCE in radiators, HVAC-R systems, engine cooling and other industrial and building applications; the Company’s expectations regarding market demand and commercialisation of THERMAL-XR® ENHANCE and related products (including Nu-Calgon CoolWorx® powered by GMG Graphene); references to typical ASTM B117-19 salt spray benchmark durations for premium automotive, building, industrial, marine and offshore coatings and statements comparing those benchmarks to THERMAL-XR® ENHANCE’s extended salt spray test duration; and the Company’s regulatory and commercialisation plans in the United States and other jurisdictions, including the implications of approvals or consent orders from regulators such as the United States Environmental Protection Agency (EPA) and the Department of Environment and Climate Change Canada (ECCC), GMG’s intentions to develop commercial scale-up capabilities, GMG’s focus in the energy savings segment, GMG’s intentions for the use of graphene lubricant additive on saving liquid fuels, expectations for R&D and commercialisation of G+AI Batteries, GMG’s ability to improve the performance of lithium-ion batteries and the Company’s four critical business objectives.
