Hi all,
I understand PU is relatively resistant to solvent welding but I was wondering if anybody has had any success with it? In particular I'm trying to weld PU plastic generated from this resin: Xencast P6 Fast Cast Polyurethane Casting Resin
I've tried methyl chloride, ethanol, isopropanol, and acetone (all lab grade/pure). Any other suggestions?
Thanks

I see no reason why it would not be watertight. Many variants of the Gorilla Glue, "swell" as they have a deliberate gap filling foaming action as they cure. This means they expand to fill any small gaps which helps them get a better bond for the likely rough applications those glues tend to see in "retail" and DIY customer usage. The VM100 Black does not foam nor does it need to as most of the intended applications are unlikely to have any significant gaps to be filled in the same way.
