DISPERMAT^® dispersers

The Dispersion Process

The most important function of the disperser is the incorporation of solids into liquids. During this dispersion process, three individual steps are performed at the same time:

• Wetting of the surface of the solid particles by the fluid components of the millbase
• Mechanical break down of solid particles associated with each other (agglomerates and aggregates) to form smaller particles
• Stabilization of smaller particles generated during the dispersion process against reagglomeration

The application of a disperser for high‒speed dispersion differs considerably to stirring and mixing where low speeds and special tools are generally used. A high‒speed disperser is highly efficient and in many cases all that is needed to achieve the required dispersion result. If however, a finer dispersion result is desired, dispersion becomes a two step process, with the disperser used for pre‒dispersion, followed by further milling in a bead or basket mill.

Applications for disperser include:

• Dyestuffs and varnishes
• Pigments and additives
• Printing inks
• Chemistry
• Plastics
• Construction chemistry
• Electronics
• Adhesives
• Coatings
• Microbiology
• Pharmacy and cosmetics
• Agrochemicals
