In Reply to: Expanded PVC, styrene, acrylic, whats the best?............. posted by BobGarby on April 30, 2003 at 10:45:37:
::Is this problem only with the expanded PVC?
Presumably, yes. But I've only worked with the expanded PVC and not tried the solid. The solid is very heavy and I don't see it having any advantages over the other products.
::Can you tell us what adhesives you are working with?
Sure, I've tired 'regular' PVC cement. The type that is fairly viscous and applied with a brush.
I also tried IPS weld-on 2007. With this product (which is water thin) you clamp the two edges together and inject the solvent along the edge. The solvent is drawn in via capillary action.
I also did the same syringe technique with acrylic solvent.
And out of frustration, I also tried to inject plain old PVC cleaner as it does disolve PVC as well.
From my limited experience I think I've listed the bond strengths in order of strongest to weakest. At least for surface to edge bonds.
All of these solvents did weld the surfaces together quite nicely.
Next I plan to try riveting the edges together and then injecting the IPS 2007.
