In adhesive technology, the term "component" refers to a single chemical compound or a mixture of compounds used to produce an adhesive. Each component has a specific function and contributes to achieving the desired properties of the adhesive. Examples of components in adhesives include hardener, resin, solvents, fillers and additives.

The choice and dosage of components is crucial for the performance of the adhesive. For example, the hardener can affect the adhesive's curing time, strength, and durability, while the resin can affect the adhesive strength, elasticity, and temperature resistance. The solvent component serves to control the viscosity of the adhesive, while fillers can influence the hardness and stiffness.

Additionally, additives such as adhesion promoters, UV stabilizers, antioxidants and flame retardants can be used to achieve special properties. Careful coordination of the components is an important factor for the quality of the adhesive and the reliability of the adhesive connection.
