Design of new pigment dispersants by controlled radical

Oct 01 2002 · The pigment 254/5 is an opaque pigment with relative low specific surface area of 15 m 2 /g whereas the pigment 254/11 is a highly transparent pigment with a high specific surface area of 94 m 2 /g. The much smaller particle size of 254/11 makes this pigment also more difficult to disperse and to stabilize.

Role of surfactants on stability of iron oxide yellow

Jul 01 2018 · For example pigment dispersion of iron oxide yellow pigment of spherulitic morphology resulted in lower viscosity over the acicular morphology . Inorganic pigments such as iron oxides due to their high specific gravity have greater tendency to flocculate and settle down and are challenge to disperse and stabilize.

disperse the solids. One of the more common organic pigments used for printing ink is phthalocyanine (Pc). An organic pigment is a dry powder often used as a coloring agent or colorant in printing inks. This powder is insoluble in the liquid carrier because of the covalent bonding in the pigment molecule and the polar liquid carrier. Insoluble
