  • Improving Color Development in Waterborne Acrylic and Styrene/Acrylic Paints

    Pigment dispersion stability, both on the shelf and in aqueous coatings, remains a priority for the paint and pigment dispersion manufacturers. Two common measures of pigment dispersion stability are the dispersion’s viscosity over time and color development when mixed in a white base paint. In a recent study with the pigment Phthalo Green (PG7) the E-Sperse® product line demonstrated lower viscosity in pigment dispersions and better color development when introduced to commercial paints than standard dispersants, such as NP9 (nonylphenol + 9 EO) and Disperbyk® 190.
