Weld-On P-70 Industrial Grade PVC/CPVC Primer is formulated for the most rigorous industrial applications and helps ensure proper pipe welding. It is compatible with all PVC and CPVC pipes and fittings and is especially recommended for use on Schedule 80 as well as large-size pipe. Once applied, this non-bodied pipe primer acts quickly to soften and dissolve the joining surfaces, helping to promote maximum fusion during welding. Follow with the solvent cement of your choice to achieve a strong, high-contact, and long-lasting joint. The benefit of P-70's strong, aggressive priming action is especially noticeable on parts being joined together in cold weather. A preferred choice of contractors worldwide, Weld-On solvent cements and primers are recognized globally for their industry-leading strength and ease-of-use. Commonly referred to as PVC glue, PVC solvent cement fuses pipes and fittings at the molecular level for a durable and long-lasting joint.
