Dispersants
A solid material dispersed in a liquid requires an additive to make the dispersion process easier and more stable. Optimal dispersion and stabilization of pigment particles is a significant factor in determining the properties of lacquers, paints or printing inks. The pigments and fillers of a formulation must be ground into small particles, moistened and distributed as stable as possible. Only then are the maximum values of color intensity, gloss, hiding power, lightfastness and weather resistance achieved.
