Geez I can't spell reading my last posts, finally Friday, phew. Never heard of you brand. But I used Marga Cipta brand for a sump build and found that even pure methylene chloride didn't melt well and get a good bond set. No matter the pin diameter still problems. I jumped on a few 90 degree welds and they broke apart at the seams like an old capillary weld, looked like dried elmers glue. That should not happen, the panels themselves should break or greatly stress before the seams fail. So, that's why I don't like cheap material. If I hadn't asked the right people the right questions I would likely have had an exploding sump about now.
Most of what I know is from James Steele. What I've gathered is that Arkema owns the plexiglas g trademark and makes the best acrylic for tanks other than polycast. They make a generic called PMACS, it's good. The list used to be large and people would use many brands years ago. The problem is some companies outsourced their manufacturing to asia and mexico in the early 2000's. For example Acrylite went from being made in Maine, USA to places like China. This made the quality control questionable with claims on inconsistency. In China some allege they stretch profits by diluting the resins in random batches. Some builders reported bad batches and failures with formerly trusted brands, then others said nothing was wrong. Lots of confusion, some businesses went under pointing fingers. Because of this, most pros won't touch anything other than these listed. Now Acrylite over 1" is still made in US/and Europe but anything under 1" is outsource manufactured now. So random brands and even formerly trusted ones might be good or it might be junk, depends who you ask.
If you're not familiar with James Steele he owned Envision Acrylics and has built tanks for 30+ years in the USA. He was the first guy to do the DIY crowd a favor to leak the technique for the wire/pin/shim method over on reefcentral years ago. He has a monster thread there that ran for around a decade with him sharing all the industry secrets and answering DIY builders questions. He shared what is now referred to the pin method. Since then capillary method is largely viewed as no longer relevant, or technologically obsolete. So use wires or pins since you aren't sure you have the best quality acrylic/ solvents/ technique, etc, you should be certain to use the strongest technique to compensate for any deficiencies. If you're not familiar with the pin/shim method, chech him out, he's the Yoda.
If you can get Plexiglas g or PMACS by Arkema, or Polycast by polyone (former spartech) in cell cast go with that. If you're stuck with random brands you should test weld some scrap 90 degree angles, let cure for a few days and give them a good ole' stomp and see how the seams hold up.
Good luck!
