Bob Smith Industries Maxi-Cure super glue is a thick gel cyanoacrlate based adhesive. The Maxi-Cure super glue is great for gluing small to large frags. The extra thick viscosity helps hold frags in position until the glue has set completely and can bridge small gaps where standard super glue would run down the surfaces.
Super glue (cyanoacrylate) is widely used for mounting coral frags to plugs, rocks, and what ever you may need to attach them to. Super glue can also be used to bond rock work when aquascaping for a seamless look. We find that if larger gaps are needed to be bridged when aquascaping either building up layers of glue, or placing a smaller rock that fits in the gap and then gluing over the top works really well. Usually when using super glue with aquascaping we will take a small amount of large grain sand to help give the glue some texture and blend it into the rock as well.
Maxi-Cure is labeled as "Extra Thick" however we do find that it is closer to standard Thick gel type glues. For a thicker consistency we recommend the IC-Gel Super Glue.
