Inside Adhesive Chemistry #worldresearchawards #researchawards #chemicalbonding
Adhesives are an essential part of modern life, yet their chemistry often goes unnoticed. From simple household glue to advanced industrial bonding agents, adhesives rely on fascinating molecular interactions to create strong and durable bonds. This video explores the hidden science behind adhesives and how chemistry makes materials stick together. At the core of adhesive performance are two key principles: adhesion and cohesion. Adhesion refers to the attraction between the adhesive and the surface, while cohesion is the internal strength that holds the adhesive together. These forces are driven by intermolecular interactions such as van der Waals forces, hydrogen bonding, and sometimes even covalent bonding. Polymers play a major role in adhesive formulations. Long-chain molecules provide flexibility, strength, and resistance to environmental factors. Depending on the application, adhesives can be designed to be pressure-sensitive, heat-activated, or chemically reactive. Epoxies, a...
