Overview of conventional adhesive technology

All adhesives in widespread use today can be considered “wet” adhesives.  These materials are typically applied to a surface in a liquid state and achieve intimate contact by flowing along the surface and wetting surface asperities.  To be an effective adhesive, the liquid must be transformed into a solid with high cohesive strength through either a chemical reaction (crosslinking), or in the case of hot melts, by cooling below the melting temperature.
