The Acrifix is a 1Komponenten polymerization adhesive. In my opinion, the best you can get the glue for plexiglass. It is a viscous solution of an acrylic polymer in methyl methacrylate, the hardens when exposed to light, is / is transparent, holds bombproof. Curing can be accelerated by putting it in the sun or simply exposes only light.
Drawback is that the stuff stinks like hell - best so outside / or gluing in the garage.
Anyone who wants to stick Plexiglas / must come to Acrifix actually not around. I have therefore also been breeding tank built of Plexiglas for aquarium. No problem, after curing easy properly rinse and down into the pool.
