A dispersion is generally a mixture of at least two substances. A solid substance that is mixed into a liquid is referred to as a suspension. However, the term “graphite dispersion” has become commonly used nowadays.
Graphite dispersions are used in applications that require a uniform and fine distribution of graphite within the carrier material. Depending on each individual application, the following dispersion properties are of decisive importance: Stability against sedimentation, surface tension, wetting behaviour on different surfaces, adhesive power on different surfaces, drying time, viscosity, pH-value and ionogenity.
In order to improve the dispersing effect, individual formulas also contain protective colloids, preserving agents and other additives in addition to graphite and a dispersion agent (water in most cases).
Graphite dispersions can be individually optimised for customer applications.
