Optimising Micro and Macro foam control additives in Pigment Mill base systems - A practical and simple guideline
A case study on optimising the impact on using Micro and Macro foam additives in a mill base is presented. Theoretically and practically, most surface active materials do interact in dispersion and wetting systems to potentially form synergistic mixtures, which can enhance performance in some way, as well as final physical properties of the coating system.
This study demonstrates that in a typical mill base used for water based coatings, using a Micro foam control agents and a Macro Foam control agent together, at optimum levels, can result in enhanced performance in processing and final let down and dry film surfaces.
This study demonstrates a simple way for formulators to determine the optimum point.
