Regardless of the pigment – including iron oxide, manganese oxide or carbon black pigments – dispersing agents or combined binder/dispersant admixtures are indispensable for physical engineering of pigment powders and pigment master batches.
The fine dispersion of the pigment particles in both the pigment powder and the suspension produced from it is critical to the subsequent application and to achieving the desired visual effect on the final product. Where good bonding properties and good dispersion are needed, lignins can prove their ability to perform.
