I am working on building a Sulfur reactor and am using rigid pvc sheet material for the project and using cell cast acrylic tube. Check out http://reefcentral.com/forums/showthread.php?s=&threadid=1266220 for more information.
Anyways.... I choose PVC instead of acrylic for the base and tops since it taps really well and I can easily glue pvc pipe through it compared to acrylic. From my searching here and online it looked like I could use Weld-On 16 for gluing the PVC to Acrylic joints. I did that and it seemed to hold OK. Well today I was doing some machining work on it and the acrylic broke right off the PVC. From looking at the failed joint the Weld-On melted into the Acrylic fine but looks like it just stuck to the surface of the PVC. The surface where the joint broke off of the PVC was still perfectly smooth.
Did I do something wrong or is Weld-on 16 not the right choice? I found an IPS Weld-on guide and it says Weld-On 16 or 40/42 will work for these materials. Before I go out and buy some 40, any ideas? Or should I be in the market for a plastic welding setup instead of trying to glue these two materials together. Thanks!!
