Effectively prepare your plastic pipe and fitting surfaces for solvent cement bonding with Weld-On® PC-64 PVC/CPVC primer-conditioner. Suitable for use with all types, classes and schedules of PVC and CPVC pipes and fittings, this solvent primer and conditioner features a dual-action formula to ensure proper pipe welding. The primer-conditioner acts as a cleanser, effectively removing grease, oil and dirt from the bonding surfaces and it also penetrates and softens 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.
