SPC Pipelock Mastic

SPC Pipelock Mastic is a filler which profiles areas to be wrapped by easing contours on pipe joints, flanges, valves, bolts, and other irregular shapes. Consists of saturated petroleum based compounds, inert fillers, and reinforcing fibers. SPC Pipelock Mastic is part of the SPC Pipelock system developed for the protection of metal surfaces in severe environments and difficult to protect applications. The system is designed to be applied over hand or power wire brushed surfaces for above ground, buried, and underwater applications. The typical system involves priming the surface with a paste (SPC Pipelock Paste), profiling around irregular shapes with a mastic compound (SPC Pipelock Mastic), and wrapping with a petroleum tape (SPC Pipelock Tape). An optional overwrap tape (SPC Pipelock Overwrap) is used for additional mechanical or electrical resistance.
