This white paper provides an overview of the different types of high speed mixers utilized in the manufacture of paints, inks and coatings. These machines accomplish a range of processing objectives which sometimes overlap. The recommendations discussed in this paper are geared towards proper mixer selection based on Ross’ experience as a provider of specialty mixing equipment to the coatings industry for over 170 years.
Regulatory requirements in the past few of decades have prompted the coatings industry to move its focus from conventional low-solid, solvent-based formulations to waterborne systems, high-solids coatings, energy-curable inks and other low-VOC technologies. This important environmentally-responsible shift coincided with exciting developments of new functionalities as a response to changing customer needs. Now faced with a growing demand for specialty and high value-added coatings, manufacturers are taking a closer look at their processing methods, particularly the mixing and milling steps. The question “What can we do better?” is asked more earnestly as coatings producers strive to improve performance and compliance while managing costs.
