Gorilla Glue is designed to bond fundamentally flat, smooth surfaces. As the glue expands while setting, it will fill minor gaps, however, such a bond is weak as the expanded glue contains entrapped air bubbles.
Moisture in the air or the materials being bonded is usually sufficient to cause Gorilla Glue to cure. While the Gorilla Group and some of its competitors claim their cured adhesive is waterproof, other brands maintain only water-resistance.
Stainability of Gorilla Glue is variable.
Gorilla Glue makers also produce Gorilla tape, Gorilla wood glue, Gorilla Epoxy and Gorilla super glue. The super glue contains rubber particles so that the bond is impact tough.
Popular Science Magazine published Gorilla Tape in their “Best of What’s New, 2006” Issue.[1]
