Key Takeaways
- • GMG's THERMAL-XR® ENHANCE coating has surpassed 30,000 hours of continuous ASTM B117-19 salt spray testing with zero corrosion, establishing a significant benchmark validation for long-term durability in harsh marine and industrial environments.
- • The graphene-based coating creates an impervious barrier that prevents oxygen from reaching metal surfaces, eliminating corrosion while simultaneously improving heat transfer performance under high air-flow conditions—dual functionality addressing both protection and operational efficiency.
- • GMG (TSX-V: GMG; OTCQX: GMGMF) has commenced bulk commercial shipments, including delivery of THERMAL-XR® to Nu, signaling transition from testing phase to market deployment across data centers, energy infrastructure, and heat exchanger applications.
- • The coating addresses critical maintenance cost reduction and equipment longevity extension across multiple industrial sectors, with particular relevance to LNG, thermal management, and corrosion-prone infrastructure requiring extended service life without degradation.
- • Testing validation through independent external US laboratory facilities using standardized ASTM protocols strengthens commercial credibility for institutional buyers evaluating corrosion protection solutions in capital-intensive infrastructure investments.
Summary
Graphene Manufacturing Group has announced a significant technical milestone with its proprietary THERMAL-XR® ENHANCE coating, achieving 30,000 hours of continuous salt spray exposure testing without measurable corrosion. This benchmark result, conducted according to ASTM B117-19 standards at an independent external laboratory facility in the United States, represents extended validation of the product's long-term durability under accelerated corrosion conditions—a critical technical hurdle for institutional adoption in industrial applications.
The coating leverages graphene-based technology to create an impervious physical barrier that prevents oxygen diffusion to underlying metal surfaces, effectively eliminating the electrochemical mechanisms that drive corrosion. Beyond corrosion mitigation, testing results indicate the coating simultaneously enhances heat transfer efficiency under high air-flow operating conditions, addressing dual operational requirements in thermal management applications. This functional combination positions THERMAL-XR® as a potential solution for equipment that must perform under both corrosive and thermally demanding conditions.
GMG has progressed beyond laboratory validation to commercial deployment, executing bulk shipments including delivery to Nu and broader market penetration targeting data centers, energy infrastructure, LNG applications, and heat exchanger restoration. The company identifies significant addressable markets in equipment maintenance cost reduction and extended asset life extension—value propositions with direct financial impact on capital-intensive industrial operators. Prior testing documentation references 20,000+ hours of corrosion protection, with the current 30,000-hour milestone representing incremental validation advancement and confidence strengthening for infrastructure and energy sector buyers evaluating long-term protective coating solutions.
