Description

Powercrete® R-95 is a high-build solvent free novolac epoxy coating designed for protecting new line pipes and pipeline rehabilitation projects that operates at temperatures up to 95˚C (203˚F). Powercrete® R-95 can be used for extra protection on top of FBE mainline coatings or as a DTM (drirect to metal) coating when an increased temperature-and chemical resistance is required.
