Multi-Layer PVC

[matt_r]

I have a customer that wants me to glue multiple sheets of PVC (sintra) together, and then cut them. This is an outdoor application.
So, what would any of you recommend for gluing these sheets together?

Thanks

Matt,
You might try "Roo Glue", in particular their "Clear" version of the product.

They state on their site that it CAN be used with PVC...

Excellent thought Bill! I even have a bottle of it in the shop. Works great on Melamine. I'm only wondering if it will hold up outside. It says its waterproof upon drying, but no other claims of weatherability beyond that.\

I may try some scrap pieces first.

Thanks,

Matt

Matt,
If for some reason there's any doubt about it's outside strength, you can probably just scuff up the surface with something like an 80 grit sandpaper, and roll on a thin coat of epoxy as well...

You can also experiment with clear PVC cement. The stuff is amazing & is used in outdoor PVC electrical conduit & pipes. If not, any good laminating epoxy will work as long as you scuff the inner layers with 60 grit paper to give them tooth.

Matt,
I use Bond & Fill PVC Glue. It dries white and is
machineable/sandable and specifically formulated for PVC Trim used outside.

In did this a few years back. We tried many things and failed before I broke down and called the Sintra help line. An engineer there turned me on to the solution, MEK. Slosh it on and slap it down quick, then apply pressure (sandbags). We ended up using a watering can and cutting the sections to be glued up down to 24"x24" pcs to make it all manageable...

What we found with all other glue/solvent weld solutions was that it became a brittle section (the glue line) that easily cracked and broke away from the piece below it. MEK actually welded the PVC together. Try it, it works!

I've never used this before, but the other products they make are pretty good.

Clear PVC Glue is the only sure thing in this application. I sell this stuff everyday along with the pvc conduit. It actually chemically reacts with the pvc to weld the material together. No scuffing , no buffing , however it doesn't have a very long open air working time but it is cheap and completely weatherproof and chemical resistant.
