A rubberized bitumen based thixotropic mastic that provides corrosion protection for below grade application to fittings, flanges, valves, tanks, mechanical couplings, anode connections and other irregular configurations. It may be backfilled in approximately 2 hours. Low temperatures and high humidity will lengthen cure time. Available in standard and zero VOC versions.
Overview
A rubberized bitumen based thixotropic mastic that provides corrosion protection for below grade application to fittings, flanges, valves, tanks, mechanical couplings, anode connections and other irregular configurations. It can be brush or spray applied, and can be backfilled in approximately 2 hours. Royston Glas-Wrap can be used to offer additional strength and impact resistance. Low temperatures and high humidity will lengthen cure time. R28 is available in standard and zero VOC versions.
