Hydrophobic acrylic copolymer pigment dispersant used in a wide range of coating formulations and also It is highly compatible with ACRYSOL™ HEUR rheology modifiers. Delivered as the ammonium salt of a carboxylate polyelectrolyte. Good color acceptance, heat stability and enhanced water resistance can be expected from coatings formulated with this product, in addition to good gloss development and corrosion resistance. The improved water resistance properties would be advantageous in primer formulations. In exterior flat and semi- gloss formulations, it displays good dispersing efficiency as measured by hiding. The gloss capability makes it suitable for use in semi-gloss and gloss enamel systems.
