An electrically conductive adhesive is a glue that is primarily used for electronics. The electric conductivity is caused by a component that makes ca. 80% of the total mass of an electrically conductive adhesive. This conductive component is suspended in a sticky component that holds the electrically conductive adhesive together.
The disadvantage of the lack of instantaneous bonding exhibited by many adhesives can be overcome by using a suitable fast-curing adhesive or a combination of a standard adhesive with a second, fast-curing adhesive (e.g. double-sided adhesive tape) or with another joining method, such as spot welding, rivets, screws, or clinching / press ...
According to the sigma bond rule, the number of sigma bonds in a molecule is equivalent to the number of atoms plus the number of rings minus one. N σ = N atoms + N rings − 1 This rule is a special-case application of the Euler characteristic of the graph which represents the molecule.
The working time to make a bond, where the surface still retains sufficient tack, can range from seconds for fast-setting HMAs to infinity for pressure-sensitive adhesives. Set time Time to form a bond of acceptable strength. Tack The degree of surface stickiness of the adhesive; influences the strength of the bond between wetted surfaces.
Adhesives may be broadly divided in two classes: structural and pressure-sensitive. To form a permanent bond, structural adhesives harden via processes such as evaporation of solvent (for example, white glue), reaction with UV radiation (as in dental adhesives), chemical reaction (such as two part epoxy), or cooling (as in hot melt).
