Defense & Security When lives are at stake, insist on the world's best ceramic armor protection. Advanced silicon carbide (SiC) materials pioneered by Saint-Gobain have protected military, law enforcement and security professionals for more than 40 years. Saint-Gobain provided the very first ceramic body armor protection to warfighters in the Vietnam conflict, and the company continues to develop and produce industry-leading protective materials. In fact, we have supplied Armor on four different continents to multiple governments for military and law enforcement personnel.
