Oxidation can be an issue on some graphite products during manufacturing processes. To mitigate this damage, GES-AGM offers a proprietary LoOx™ treatment to ensure extended durability and performance on many of our products. This solution is offered in our U.S. and Brazilian facilities, and more information about this effective treatment is available through our sales team.
