Modified Polyamine Epoxy
An advanced generation, 100% solids, high-build epoxy for the protection of steel and concrete. It provides excellent resistance to abrasion and is suitable for immersion service in potable water and wastewater environments. Specialized curing mechanism allows for faster cure response with airless spray application.
