CPP Perma-Shield

Generic Type

Common Usage

This 100% solids polycyclic amine epoxy liner is formulated using Tnemec Company’s proven Perma-Shield® technology for enhanced resistance to severe H2S environments. Applied as an ultra-high build, high-strength microfiber-reinforced polymer (FRP) applied liner, Series E456 protects against corrosion while sealing below-grade structures from inflow and infiltration (I&I). Specifically designed for rehabilitation and lining of wastewater treatment plant (WWTP) structures and other large wall, open, or semi-open structures where high film strength and durability are required to deliver sealed barrier protection against microbiologically induced corrosion (MIC), severe hydrogen sulfide (H2S) and I&I. This is achieved by the product’s formulated balance of high strength properties, acid protection, and high surface acceptance to saturated surface dry (SSD) conditions with the ability to cure within high humidity environments. Formerly CPP Sprayliner.
