Adhesive, also known as glue or paste, is a substance that is used to join two or more surfaces together by creating a strong bond. It is typically a viscous liquid or a solid in the form of a strip, tape, or dot. Adhesives are commonly used in various industries, such as construction, manufacturing, and crafts, and can be made from natural or synthetic materials. They work by creating a molecular attraction between the surfaces, resulting in a durable and long-lasting bond. Adhesives come in a variety of types, including water-based, solvent-based, and hot melt, each with its own unique properties and uses. From repairing broken objects to creating intricate art pieces, adhesives play a crucial role in our daily lives, making it easier to stick things together and keep them that way.
