Can I use contact cement on PVC?

However, contact cement, hot glue and super glue all have reasonable to good adhesion on PVC, so they can be used to glue PVC if the application is not too demanding. I would not recommend it for plumbing though. No. PVC cement lends it’s strength by chemically welding the plastic surfaces together.
