Dura-Plate 6100 high-build, high-physical-strength epoxy lining for manholes and other severe wastewater and sewer collection applications from Sherwin-Williams is suitable for use on ductile iron pipe, steel and concrete substrates. It offers a dry time of 30 minutes to touch and return to total immersion service in 12 hours. This speed decreases the potential pinholes in the applied film due to outgassing, ensuring monolithic film coverage to increase service life.
