GMG's THERMAL-XR ENHANCE coating surpasses 30,000 hours in salt spray testing Proactive uses images sourced from Shutterstock

Graphene Manufacturing Group Ltd (TSX-V:GMG, OTCQX:GMGMF) said its THERMAL-XR ENHANCE coating has passed 30,000 hours of salt spray testing at an external lab.

THERMAL-XR ENHANCE is a coating system designed to improve the conductivity of corroded heat exchange surfaces, as well as improve and maintain the performance of new units at peak levels.

The process coats and protects heat exchange surfaces while rebuilding 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.

Craig Nicol, GMG's managing director and CEO, said reaching more than 30,000 hours of testing with no observed corrosion is a significant validation of THERMAL-XR ENHANCE in one of the harshest standard corrosion test environments available.

Nicol noted that many premium automotive, building and industrial coatings are benchmarked at around 1,000 hours, while high-performance marine and offshore systems are typically tested at 2,000 hours or more, with extended programs 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,” Nicol said.

Jack Perkowski, GMG's chairman and non-executive director, pointed to measurable benefits in space cooling, refrigeration and data centre applications under 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,” Perkowski added.
