Bond- HUD to PVC

[joe]

I'd suggest a glue up test! Lets say 2"X4' of the materials laminated up. Lay it out in the sun and see what happens. PVC is a little floppy when it heats up. I'd be willing to lay some money on this one. The reason many of us have been using aluminum in combination with HDU is the expansion co-efficients are similar. Even if you take use strips of silicone adhesive, which are supposed to allow for expansion, it's going to warp. But don't take my word for it, do the tests.



Epoxy: All brands I've used worked well. Some are a little thicker like PB Resin, which I prefer. But those at your hardware should work well. I purchased a tube last week which goes in the regular calking gun. It's thick and good for vertical use.
