Industry-Leading Pigment Dispersion Machines for Paints and Coatings Manufacturers
Milling organic and inorganic pigments to a specific particle size is crucial for achieving your desired color strength, gloss, transparency, and opacity, and Hockmeyer has a rich background in the paints and coatings industry, which contributes to the company’s expertise in this field. Using a rapid-flow vacuum milling process allows manufacturers to enhance efficiency and boost profits by reducing processing time, improving yields, and eliminating air entrapment. This method enables faster and purer particle size reduction and deagglomeration, eliminating the drawbacks of air bubbles in the feedstock.
Paints and Particle Analysis
In paints, color strength and transparency testing are common methods of quality assessment, but a more comprehensive examination is necessary for process optimization. Accurate particle size analysis is vital for identifying distribution and adjusting the mill to meet target requirements.
Producing nano-pigment dispersions involves intricate procedures beyond just grinding to small sizes. It includes wetting out, mixing solid and wet components, chemical additive interactions, and stabilization. Efficient milling with air removal eliminates the cushion effect caused by air bubbles and ensures more particle impacts for precise particle size, tight distribution, and accurate volumetric measurement.
High-viscosity mixing and milling equipment with tank scraping, helical blades, and an auger are required for incorporating raw materials effectively. A vacuum is also essential for removing trapped air, maximizing particle-to-particle interaction for enhanced deagglomeration and particle size reduction.

Pigment Dispersion for Paints and Coatings FAQs
How can Hockmeyer’s equipment assist in the pigment dispersion process?
Hockmeyer's equipment plays a crucial role in the pigment dispersion process thanks to its rapid flow and recirculation technologies, which ensure consistent and tight particle size distributions, something that’s vital for maintaining high product quality. Furthermore, its equipment improves efficiency and productivity by drastically reducing process times, contributing to overall operational effectiveness.
Is there a way to test how well Hockmeyer’s pigment dispersion equipment works?
Absolutely! We understand the process can be challenging, so we have equipped our testing facility with laboratory and scalable pilot models of our most popular equipment. We also offer free initial testing to help you evaluate the performance of the equipment and find the pigment dispersion solution that’s the best fit for you.
When does dispersion occur in the manufacturing of paints and coatings?
Dispersion involves a two-phase process to ensure the coating has consistent color strength, transparency, and other desired properties. First, wetting and deagglomeration combine wet and dry ingredients, applying high shear to separate particles. Then, the milling operation employs multiple impact points like media beads, pegs, or screens to deagglomerate particles further and reduce their size effectively.
