Coprenal 242 6E242

Coprenal 242 6E242 is a solvent-free, two-component epoxy resin liquid plastic with high abrasion resistance for steel and concrete surfaces subjected to extremely heavy wear in hydraulic engineering and wastewater treatment applications. As a cost-effective corrosion protection solution for large, contiguous surfaces, it can be applied as a thick-film system with film thicknesses of up to 500 µm (wet film thickness) per application, forming a highly abrasion-resistant, mechanically and chemically durable surface with good adhesion to metallic and mineral substrates. Coprenal 242 6E242 is repairable, touch-upable, and suitable for spray application, thereby ensuring efficient application and long-lasting performance even under demanding operating conditions.
