Adhesives are substances used to join two or more materials together. They can be in the form of liquids, pastes, or solids and are designed to create a strong bond between surfaces. Adhesives work by filling the gaps between surfaces and forming a bond that is stronger than the materials themselves. This is achieved through various mechanisms, including mechanical interlocking, chemical bonding, and physical adsorption.

Adhesives are widely used in various industries, including construction, automotive, electronics, and packaging. In construction, adhesives are used to bond wood, metal, and other materials together. In the automotive industry, adhesives are used to assemble car parts and to repair damaged surfaces. In electronics, adhesives are used to attach components to circuit boards and to encapsulate electronic devices. In packaging, adhesives are used to seal and bond packaging materials together.

Adhesives can be classified based on their composition, application method, and the type of surfaces they bond. Common types of adhesives include natural adhesives, synthetic adhesives, and pressure-sensitive adhesives. Natural adhesives are derived from natural sources, such as animal glue or tree sap. Synthetic adhesives are man-made and include materials like epoxy, cyanoacrylate, and polyurethane. Pressure-sensitive adhesives are designed to bond to surfaces under light pressure and are commonly used in labels and tapes.

The choice of adhesive depends on various factors, including the type of materials being bonded, the strength required, and the environmental conditions. Adhesives must be carefully selected and applied to ensure a strong and durable bond. Improper use of adhesives can lead to failure, which can result in costly repairs and downtime. Therefore, it is essential to follow the manufacturer's instructions and guidelines when using adhesives.
