Weld-On® P 70™ is an industrial grade, low VOC emission, non-bodied, fast-acting primer. The strong, aggressive action of Weld-On® P 70™ primer rapidly softens and dissolves the joining surfaces of PVC and CPVC pipe and fittings. The benefit of this priming action is especially noticeable on parts being joined together in cold weather. Available in clear and purple; the latter allows easy identification when used on the joining surfaces. Weld-On® P 70™ primer, when used in conjunction with appropriate Weld-On® solvent cements, will make consistently strong, well-fused joints. It is essential that the joining surfaces of pipe and fittings be softened and remains softened prior to assembly. The main function of the primer is to expedite the penetration and softening of the surfaces. Its rate of penetration into the joining surfaces is more rapid than that of solvent cement alone. Weld-On® P 70™ primer is suitable for use with all types, classes and schedules of PVC and CPVC pipe and fittings. It is specially recommended for use on Schedule 80 and large pipe sizes. Weld-On® P 70™ has a shelf life of three years in a tightly sealed container.
