TECHNICAL FIELD

The present disclosure relates to a primer for use with solvent cement in bonding plastic components together, and more particularly, for use in bonding plastic pipes, fittings, or other components.

BACKGROUND

Primers are used in the solvent cement process to help prepare plastic pipes, fittings, surfaces, and other articles or objects for joining components or adhesion by cleaning and softening the object to maximize adhesion once a solvent based adhesive is subsequently applied. The pipes, fittings, or other objects being adhered are typically made from PVC (polyvinyl chloride), CPVC (chlorinated polyvinyl chloride), ABS (acrylonitrile-butadiene-styrene), and other thermoplastics or polymers. Before applying a solvent cement, the surfaces to be joined are normally covered with a primer containing a solvent capable of at least partially dissolving or “softening” the surface to be bonded.

SUMMARY

Provided herein are primer formulations for solvent cement bonding comprising cyclopentanone and, optionally, at least one additional organic solvent.
