Ensure proper pipe welding while keeping environmental impact to a minimum with Weld-On 14928 ECO 721 Blue PVC Specialty Solvent Cement 1 qt. Designed for use with solvent cements, this ultra-low-VOC PVC/CPVC cement primer offers a significantly lower solvent emissions rate than other solvent cements on the market--but without compromising performance. The significant reduction in odorous fumes and emissions helps improve workplace conditions for pipe installers. Compatible with both PVC and CPVC pipes and fittings, this pipe primer ensures that every joint you weld is properly fused. Once applied, it acts quickly to soften and dissolve the joining surfaces, helping promote the maximum fusion can take place. Follow with the solvent cement of your choice to achieve a strong, high-contact, and long-lasting joint.
