adhesive

An adhesive is a substance that bonds two surfaces together by creating a strong connection at the microscopic level. It works by filling the tiny gaps and irregularities between the surfaces, forming a cohesive link when it hardens or grips. Adhesives vary for different materials and applications, from glues and tapes to industrial bonding agents. Their effectiveness depends on factors like material compatibility, surface preparation, and curing process. Essentially, adhesives serve as the "glue" that allows materials to stay joined reliably without mechanical fasteners, enabling construction, repairs, and manufacturing across various industries.
