Description
[Lutz File & Tool Co., Cincinnati, OH] A registered trademark for an strong waterproof wood glue. The Original Gorilla Glue formula was first introduced in 1994. It is a water-activated, thermosetting polyether-type polyurethane resin formula. The manufacturer states that Gorilla Glue® is 100% pure and does not contain fillers, plasticizers, or dangerous solvents. On activation, the glue expands approximately 3x its original volume. However, it is not recommended for use in gap-filling. The cured color of the glue is tan. Original Gorilla Glue is indicated for use on a variety of materials including wood, stone, metal, ceramic, foam, glass, concrete, etc. Gorilla glue is useful on many types of plastic but should not be used on Polypropylene or Polyethylene, or on rubbers with high oil or plasticizer contents. The resulting adhesive bond is waterproof, strong, and temperature resistant.
Since the development of the original glue, the company has expanded to offer Gorilla tape, Gorilla Super Glue, Gorilla Wood glue, Gorilla Construction adhesives and more. Some products are listed below:
| Product | Composition | Characteristics |
|---|---|---|
| Original Gorilla Glue | Polyurethane | Waterproof, dries tan, sandable, paintable, expands curing curing |
| Clear Gorilla Glue | Hybrid | Water resistant, dries clear, sandable, paintable, does not expand on curing |
| White Gorilla Glue | polyurethane | Waterproof, dries white, sandable, paintable, expands during curing |
| Gorilla Super Glue | ethyl cyanoacrylate | Do not use outdoors, dries clear, sandable, not paintable, fast setting |
| Gorilla Epoxy | epoxy | Water resistant, dries clear, sandable, paintable |

Working Properties
- Original Gorilla Glue - Moisture activated; therefore, a small amount of moisture should be applied to one join surface. The glue should be applied to the other, dry surface before clamping the join together. When joining dense hardwoods, it is useful to dampen both surfaces before gluing. Slick or burnished surfaces should be scored before application to provide grip. Because Gorilla Glue expands in volume on activation, only a thin layer is required to achieve a successful join. An amount of ½ oz. is recommended per square foot of join surface. Excess uncured squeeze-out (wet glue) may be removed from a surface with a dry cloth or a standard paint thinner. Dried gorilla glue may be removed mechanically. Working time: 20 minutes. Sets in 1-4 hours. Completely cures in 24 hours. Gorilla glue should be allowed to cure between 40-130 F. Gorilla glue may be stained following its curing. It is useful to sand the surface of the glue before staining. It may also be painted with oil-based and spray paints.

- Clear Gorilla Glue - Similar to the Original formula. This formula is also moisture activated and should be applied as the Original formula. It will not expand on activation.
