Weld-On USA PVC Adhesive Weld-On 721 473 ml

Weld-On 721 is a medium-bodied, fast-setting PVC solvent cement with high strength and low VOC content in a convenient 473 ml package. It is suitable for rigid PVC with interference fit for Sch. 40 up to 6″ (160 mm) and Sch. 80 up to 4″ (110 mm). It belongs to the premium range of cements for irrigation, waste water, pools, spas, plumbing and non-pressure applications.

It can be used as a one-part, primer-free cement on PVC Sch. 40 and SDR pressure water systems up to 4″ (110 mm) in irrigation, pools, spas and non-pressure applications, where local codes do not require primer. Do not use without primer for other applications or sizes, such as industrial Sch. 80. When primer is used, the joints must be allowed to cure sufficiently before backfilling.
