The first step in the pigment dispersion process is providing the platform for these agglomerates to be broken down. Wetting involves replacing the air and moisture between the pigment particles with a binding solution (also called a pigment dispersing agent). The binding solution gets into the spaces that are currently filled, wetting the ...

When preparing for a pigment dispersion, there are a couple of considerations you should keep in mind to ensure effective, high quality results. One of the keys to proper pigment dispersion, and one of the most neglected processes in the industry, is making a good premix. The better the dispersion before taking the product over to the mill the ...

It prevents pigment settling and reduces sag and the tendency to form surface defects. In multi-pigment paints, slight co-flocculation of the pigments improves color uniformity and reduces the possibility of convection flow related defects on drying or baking. Co-flocculation with extender pigments can be particularly effective in these respects.
