Question:

Gluing plastic to PVC?

by  |  earlier

0 LIKES UnLike

I've assembled a PVC potato cannon, and one of the ignitor electrodes is surrounded by plastic, and I need to find some type of adhesive to glue it to the PVC. And it needs to be able to withstand the pressure that shoots a potato 100 yards.

PVC glue didn't work, maybe it's only PVC to PVC. Superglue?

Thanks

  1. I don't know of a product that blends or melts or bonds plastic with PVC.. I've heard of plastic weld for plastic and pvc glue for pvc but not one that will bond each to the other.

    maybe you can drill a hole in a pvc plug (threaded) and leave a inside sholder to retain the the fitted ignitor and a small center hole for the wires and assemble into female threaded PVC fitting


  2. PVC "glue" only works after you have used PVC cleaner/solvent. It is a 2 step process. Get a small can of PVC glue [actually it's called PVC cement] and a small can of solvent. Following instructions, first apply the solvent to both pieces with the built in applicator...then [again, according to the can instructions] coat both pieces with the cement. QUICKLY push the two together, twist them slightly to distribute the glue, and QUICKLY  position the pieces where you want them. Hold them for 15-20 seconds, and the glue will set. [Actually it's more of a welding process than gluing...but that's just theory, not practice]. Such properly made joints are very strong, and usually all that is needed for potato guns.

  3. Maybe Epoxy or Superglue or JB Weld!!!  Good Luck!!!

  4. Goop, you can buy it at the hardware store for about $5.00. it bonds to anything, i've glued the plastic trim back on the chrome bumper of an old beater station wagon, and then used it to push other vehicles, a dumpster on a job site, etc. and it never even moved. you also won't be able to remove the ignitor ever again though.

  5. Otis makes an all purpose glue that is for abs,PVC, and CPVC it is next to the other PVC glues
