9179  has excellent wettability. Compared with small molecular wetting and dispersing agents, it has excellent ability to prevent back coarsening, excellent dispersion and storage stability. Compared with other dispersants, it has less hydrophilic group, good water resistance and little effect on water resistance of paint film. It has wide compatibility with many water-based base materials. It is the first choice of dispersant for resin-containing grinding. It can stabilize various pigments including inorganic pigments, organic pigments and carbon black. It can also be used in resin-free systems. Even if there are organic amines, rheological additives, wetting agents and organic co-solvents in the abrasive, it will not affect its dispersion performance. This high molecular weight additive improves color strength, transparency, gloss and storage stability via steric stabilization mechanism.There is no adverse effect on the stability of those pH-sensitive systems.
