The ISO 8780-3 standard specifies a method for dispersing pigments and fillers using a high-speed impeller mill. This method is suitable for moderately high viscosity grinding materials, enables preliminary pigment dispersion and serves as a basis for further use of Miscellaneous equipment. The standard is used in conjunction with the evaluation method in ISO 8781 to ensure accurate dispersion results. High-speed impeller mills can provide a higher shear force and are suitable for dispersion with high viscosity or pigment concentration, but are not suitable for full-size formulations for mass production.
