GMG says U.S. EPA approval opens the door to graphene coating sales in North America
Graphene Manufacturing Group said on March 31, 2026, that its THERMAL-XR graphene coating has received U.S. EPA approval, a regulatory step that allows the company to move deeper into the North American HVAC-R market through distributor Nu-Calgon. The company is now looking to turn that clearance into early revenue as it expands sales in the United States and Europe.
