At NINGBO INNO PHARMCHEM CO.,LTD., we often formulate our advanced dispersants using a synergistic combination of sodium polyacrylate and ammonium polyacrylate. This dual-component approach leverages the unique, yet complementary, properties of each salt of polyacrylic acid to deliver superior performance across a range of industrial applications, most notably in coatings.

Sodium polyacrylate is well-known for its excellent water-absorbing and dispersing capabilities. Its negatively charged carboxylate groups provide robust electrostatic repulsion, which is fundamental to preventing particle aggregation and maintaining stable suspensions. This contributes significantly to improved pigment dispersion and the reduction of slurry viscosity, allowing for higher solids loading in formulations.

Ammonium polyacrylate, on the other hand, offers some distinct advantages. As an ammonium salt, it can contribute to a lower ash content upon ignition, which can be beneficial in certain high-temperature applications or when residue is a concern. Furthermore, its performance characteristics, such as good rubbing fastness in floor paints mentioned in some literature, highlight its specific utility. In formulations, it often complements sodium polyacrylate by fine-tuning the overall dispersion characteristics and stability.

The synergy between sodium and ammonium polyacrylate in a single dispersant formulation allows for a more comprehensive approach to particle stabilization. This combination can provide enhanced performance in terms of broader pigment compatibility, more efficient viscosity reduction across a wider range of particle sizes, and improved overall system stability. The mixed salt approach can achieve dispersion qualities that might be difficult to attain with either component alone, leading to better freeze-thaw stability and color development.

These combined benefits are invaluable in demanding sectors like water-based coatings, where achieving uniform pigment distribution, reducing processing time, and ensuring long-term product integrity are critical. Similarly, in paper manufacturing and ceramic processing, the ability to achieve stable, low-viscosity slurries with high solids content is paramount for efficient production and high-quality output. NINGBO INNO PHARMCHEM CO.,LTD. harnesses this synergistic power to deliver advanced chemical auxiliaries that meet and exceed industry expectations.
