Adhesive materials are substances used to bond two surfaces together. They can be found in various forms, such as liquids, pastes, or tapes, and are commonly used in construction, manufacturing, and everyday household tasks. Examples include glue, tape, and epoxy, each designed for specific applications based on their strength and flexibility. These materials work by creating a strong connection between surfaces through chemical or physical interactions. Some adhesives are designed for temporary use, while others provide a permanent bond. Understanding the properties of different adhesive materials helps in selecting the right one for a particular task.
