Hmmm .....
The YouTube reviews [that I've looked at to-date] seem to conclude that differing adhesives are required for different plastics. Recently I repaired the shattered boss on a small sixty odd year old waxy/nylon type thumb wheel. This plastic is always difficult to repair and is perhaps best hot-welded. In the end [after several attempts] I managed to tack it all together with superglue, and then reinforced the outer perimeter of the boss with a fillet of epoxy resin.
One concern with UV catalysed adhesives seems to be that it doesn't seem to be activated on concealed surfaces i.e. where the UV cannot penetrate. They say that it's not a 'glue' but rather a 'weld'. However - plastic solvent weld adhesives have been around for quite a while [primarily used in plastic plumbing applications]. Admittedly, these latter adhesives don't set 'instantly' - but they do rely on melting and re-forming the parent plastic ..... which Bondic doesn't seem to do.
