AVEKA was approached by a customer to help with the scale-up of their pigmented nano-dispersion for a medical application. The customer’s existing formulation had a very low solids concentration, which would have resulted in large batch sizes and a high cost of production and shipping.
AVEKA conducted a series of small test runs on lab-scale dispersion equipment to vary pigment and dispersant concentrations, feed rates, energy inputs and ingredient addition. AVEKA was able to identify a balanced formula with a high concentration level that was optimal for high-energy bead milling. The high solids content of the new formulation reduced batch sizes and shipping costs, allowing for affordable production costs.
