Duct tape, or duck tape, is cloth or scrim backed pressure sensitive tape often sealed with polyethylene. It is very similar to gaffer tape which was designed to be cleanly removed, which this tape is not. It is generally silver or black in color but other colors are available. With a standard width of 1+78 inches (48 mm), duct tape was originally developed during World War II in 1942 as a water resistant sealing tape for ammunition cases. Permacel, then a division of Johnson & Johnson, used a rubber-based adhesive to help the tape resist water and a fabric backing to add strength. It was also used to repair military equipment quickly, including jeeps, firearms, and aircraft because of these properties.

In military circles, this variant is known as "gun tape", typically olive-green, and is also known for its resistance to oils and greases. It is also called "Duck Tape", "riggers' tape", "hurricane tape", or "100-mph tape"[1][2]—a name that comes from the use of a specific variety of duct tape that was supposed to hold up to 100 mph (160.93 km/h) winds.

Common uses

Duct tape is commonly used in situations that require a strong, flexible, very tacky tape. Some have a long-lasting adhesive and resistance to weathering.

A more specialized product, commonly known as gaffer tape, is preferred in entertainment circles, as it does not leave a sticky residue when removed. It comes in matte black, and is more easily torn into thin strips for precise application.

Duct tape, in its guise as "racer's tape", has been used in motorsports for more than 40 years to repair fiberglass bodywork. Racer's tape comes in a wide range of colors to help match it to common paint colors.[3] In the UK it is usually referred to as "tank tape" in motorsports use.[4]

Duct tape is not used for sealing ductwork. Building codes usually require a special fire resistant product, often with a foil backing and long lasting adhesive.
