Black Swan Mfg. Co. 08100 Purple Primer 4-oz Can

Black Swan's Purple Primer is a purple, non-bodied, fast acting solvent used to soften, clean and prepare plastic pipe and fittings prior to assembly. Purple Primer can be used with all types, schedules and classes of PVC and CPVC pipe and fittings. A low VOC formulation. Purple Primer accomplishes two things. First, it will clean the pipe and fittings of any dirt, oil, grease and other foreign matter. If the plastic is dirty before making a connection it will be more difficult for the cement to bond the pipe and fitting together. Second, Purple Primer will soften the plastic. This allows the cement the opportunity of skipping a step (softening the plastic) and to go immediately to the process of fusing the pipe and fitting together. Note - softening the plastic in cold weather is especially important because it will noticeably speed up the process of making a solvent cement joint.
