Aqueous and Non-Aqueous - E-Sperse® pigment dispersants provide low usage rates, improved color strength, and improved rheological properties.
E-Sperse® dispersants may be utilized alone or with polymeric dispersants to lower viscosity and improve the stability of the pigment dispersion, thus allowing higher solid levels.
Pigment dispersions produced from E-Sperse® dispersants offer great compatibility with styrene acrylic and acrylic latexes, short-, medium-, and long oil alkyds, and epoxies. When using E-Sperse®surfactants in the same system to disperse pigments, as well as emulsify or disperse latexes, a lower surfactant load may be realized. Use as a dispersant in alkyd and epoxy paints also promotes freeze-thaw stability.
E-Sperse® surfactants are utilized at a rate of up to three percent in polymeric dispersant stabilized pigment concentrates as found in the ink industry, and up to ten percent on the weight of the pigment in non-polymeric dispersions. Usage may vary depending on the quality of the pigment, particle size, and equipment used. For recommendations and recipes, please see the pigment chart.
E-Sperse® RS-series products can be used as pigment dispersants in either aqueous or the ink industry's solution acrylic systems. E-Sperse® RS-1616 reduces viscosity in pigmented solution acrylic systems as much as 30%. Formulas can be provided upon request.
NEW REPORT: PIGMENT DISPERSANTS FOR IMPROVING COLOR DEVELOPMENT IN WATERBORNE ACRYLIC AND STYRENE/ ACRYLIC PAINTS
Comparing the effectiveness of the E-Sperse® Product Line to Standard Industry Dispersants
Of greatest importance to the consumer is ease of use of a paint. Pigment dispersion stability on the shelf and in aqueous coatings remains a priority for paint and pigment dispersion manufacturers. This study looks at improvement of the shelf life of the pigment dispersion, as well as enhancement of the compatibility of the pigment dispersion with waterborne, white-base, latex paints.
