Product Introduction
403 Anti-Static Non-Sparking Mortar is a cementitious composite topping for industrial floors where electrostatic discharge and spark risks must be controlled. Applied on new or existing concrete, it forms a dense, conductive and wear-resistant surface. The system delivers stable electrical performance, abrasion resistance and long-term durability in petrochemical, pharmaceutical, electronics, logistics and defense sites.
