Hydrophobic acrylic copolymer pigment dispersant. It is a specially-engineered high performance pigment dispersant for interior and exterior coatings. In gloss formulations (including high-gloss acrylic enamels), facilitates the full development of the gloss potential of the binder. Used in conjunction with nonionic rheology modifiers, it improves flow and film-build and offers an alkyd-like feel when brushing. Well suited for formulating metal and wood primers, and stain and corrosion-resistant topcoats for a variety of substrates. Delivered as ammonium salt.
