Tape adhesives are sticky materials used to bond surfaces together. They come in various forms, such as pressure-sensitive tape, which sticks when pressed onto a surface without needing heat or water. These adhesives are commonly found in everyday items like scotch tape and masking tape. Different types of tape adhesives serve specific purposes. For example, double-sided tape allows for bonding on both sides, while duct tape is known for its strength and versatility. The choice of tape adhesive depends on the materials being joined and the required durability of the bond.
