Great Oooglie Moooglie! What did you do to that poor panel Shane?
I have to jump in (now that I'm back from the long weekend - Happy New Year by the way everyone!) and get some information going here...
This isn't a chemical issue, the warp is far too clean to be a chemical thing - plus the chemicals cause the plastic to pull away and start pulling apart. This allows the chemical to get in-between the 2 pcs and eat the glue. The glue fails and then the panels explode. If you haven't seen it yet, just try not rinsing one after you have it in the dip tank for a bit. It's quite scary...
What this looks more like to me is that there was a direct heat source near the edge of the plastic. Unfortunately, the plastic has a lower warping point than the mesh has melting point. The mesh should hold up to temps well in excess of 175-200 degrees depending on the mesh count. Some manufacturers even subject the mesh to heat treatments to make the threads last longer. The plastic, on the other hand, will take temps of 100-120 degrees or so before it starts to soften. The melting point of the product (PVC) is 160 degrees. This is quite a ways under even the finest mesh counts will take.
I'm pretty sure that you just got them a bit too hot and under the pressure of the tension, they failed. Shoot me an email (
