Water is an enemy of most adhesives, so duct tape’s adhesive and top layer work together to repel moisture and maintain adherence for as long as possible. Water-resistantĭuct tape is designed to adhere and support in the harshest environments. However, it doesn’t cure or harden like epoxy-based adhesives, so multi-use or general-purpose duct tape can be removed easily. The glue on the underside of duct tape is designed to attach securely to most objects. The surface of cardboard has tiny fibers that prevent duct tape from sticking properly.īestReviews Duct tape’s best features Easy tearingĭuct tape is sturdy, but a single-layer strip can easily be torn horizontally or vertically, so you can customize the tape on the fly. How not to use duct tapeĪvoid porous surfaces: Porous surfaces can be problematic for duct tape, so avoid using it on brick or concrete.Ĭleanliness matters: Surfaces with a lot of dirt, dust, or small debris will defeat duct tape.įorget cardboard: Anyone who’s watched with frustration as duct tape peels away from a cardboard box knows it’s not the best tape for moving day. So check the label so you know what type of adhesive you’re dealing with: polymer or rubber. It’s stickier and adheres much more strongly, but it is harder to remove and leaves behind more residue.Ĭleaning up that adhesive residue can be a chore, even with products available to help loosen it. This type of glue adheres to a surface evenly and doesn’t cure or become stickier, so it’s easy to remove with little residue left behind.Ĭertain types of duct tape that are developed for use in more extreme conditions or need to hold more securely use rubber-based glue. General-purpose duct tape uses polymer-based glue. The sticky facts about duct tape adhesive Thread count is the biggest difference between duct tape that is best used for patching surfaces and duct tape that can hold a car bumper in place while you drive to the auto body shop. The higher the thread count of the cotton fabric, the stronger the duct tape. Without this layer, duct tape would just be a fancier, fragile version of masking tape. The middle layer of duct tape is cotton fabric, which makes the tape stretchy and adds lots of strength. But Stoudt got the credit for its invention due to her persistence. And, after a word from him, the War Production Board quickly approved the development of the new tape.īecause manufacturers were cooperating with each other to boost production during the war, Johnson & Johnson was given the task of creating a strong, water-resistant cloth tape. Undeterred, she wrote a letter to President Roosevelt with diagrams. Stoudt tried to convince her managers and government inspectors that the tape was a better solution, but she was ignored. Ammunition boxes were hard to open in the field because they were sealed with paper tape and dipped in wax to prevent water from getting inside. Adhesive glue: The bottom layer is either a polymer-based glue or a rubber glue.ĭuring World War II, Vesta Stoudt, who worked at a factory making ammunition, came up with the idea for a better tape that would securely seal ammunition boxes and be easy to remove.It’s thin enough that the tape can still be torn by hand.

Cotton fabric: The middle layer is a loose weave cotton fabric that adds tensile strength to the tape.This material can take on colors, patterned prints, or just remain clear.

Polyethylene: The top layer is water-resistant polyethylene.
