High Shear High Speed Mixer / Disperser / Dissolver

Overview

In the past few decades, regulatory requirements have prompted the coatings industry to shift its focus from conventional low-solid, solvent-based formulations to waterborne systems, high-solids coatings, energy-curable inks, and other low-VOC technologies. This environmentally responsible shift coincides with exciting developments in new functionalities in response to changing customer needs. Faced with a growing demand for specialty and high value-added coatings, manufacturers are scrutinizing their processing methods, particularly the mixing and milling steps. The question “What can we do better?” is being asked more earnestly as coatings producers strive to improve performance and compliance while managing costs. Various dispersion tools are employed in the production of paints, inks, and coatings. Some of these technologies are relatively new solutions to age-old processing issues. Mixer selection is based on factors including viscosity profile, shear requirements, order of addition, and throughput. MPI High-Speed Dispersers, High-Shear Mixers, Three-Roll Mills, and Multi-Shaft Mixers are widely used for various applications throughout this industry.

Product Applications

Artist Colors – high solids pigment oil-based paints.

Electronic Coatings – Electronic circuitry and devices require protective materials to shield them from the elements. Whether of low or high viscosity, an intermediate or the final coating, there is an MPI Mixer suitable for this application.

Fumed Silica Dispersions – Manufacturers of paints and coatings benefit from purchasing fumed silica in powder form and preparing the dispersions themselves rather than ordering silica dispersions, which entail higher shipping costs. Depending on the maximum viscosity and final grind, various MPI Mixing Equipment allows manufacturers to create these dispersions in-house.

Inkjets – In the inkjet industry, the shift away from dye-based inks towards pigment-based inks to deliver products of greater resistance to weathering and exposure to moisture has also necessitated mixing equipment that efficiently grinds pigments with reduced or no downstream milling necessary. Various MPI high-shear mixing devices, including the PreMax, have dramatically improved the production of inks for inkjet printers.

Lithographic Pastes – high-viscosity pastes composed of oleoresin varnish filled with carbon black are prepared using MPI Double Planetary Mixers and Discharge Systems, which are economical alternatives to sigma blade mixers. Recent developments in mixing equipment and coatings formulations have shown that an investment in high-viscosity vacuum premixing can yield a larger dividend in productivity than a comparative investment in downstream milling.

Paints – Various MPI Mixers are used to disperse pigments and extenders used in paint including Titanium Dioxide (TiO2), Calcium Carbonate (CaCO3), Clay, Talc, Silica, Mica, and other coloring or plastic pigments into water, oil, or solvent, along with modifiers and additives.

Silicone Coatings – Silicone-based substances are used to create coatings and encapsulants for electronics, automobiles, aerospace, medical devices, etc.

Specialty Inks – metallic/conductive, fluorescent, security, phosphorescent, and others.

Standard Printing Inks – web offset ink, sheet-fed ink, soybean-based ink, rubber-based ink, water-based ink, UV ink, laser ink, process ink for color printing, and others.

Steel Activators – coatings applied to steel prior to plating.
