SPC Pipelock Paste is a preparatory priming paste used to displace surface moisture, passivates surface oxides and fills small irregularities in the substrate. It consists of saturated petroleum based compound and passivating agents. SPC Pipelock Paste is a special primer paste that contains wide spectrum biocides. The SPC Pipelock 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.
