CEX-320 System

PolyX CEX-320 System

PolyX CEX-320 System is engineered to meet agency specifications for polyester polymer concrete, ensuring unmatched performance for demanding infrastructure projects. This system combines a precisely formulated polyester-polymer resin binder with high-hardness, low-absorption aggregates for bridge deck overlays. All components — resin, aggregates, primer, and additive agents — are supplied as part of a qualified, single-provider system to ensure consistent results. CEX-320 is impermeable to chlorides, protecting the underlying structure from salt and chemical intrusion. Designed for rapid return to service in as little as three hours, CEX-320 is the go-to system for bridge deck overlays, bridge header repair at wheel ruts, and often used for delamination repairs.
