Achieving the best possible performance from pigments in coatings, inks, and other formulations hinges not only on the quality of the dispersant but also on its correct dosage. At NINGBO INNO PHARMCHEM CO.,LTD., we emphasize the importance of precise formulation, and understanding dispersant dosage is a critical step. For those looking to buy dispersants and maximize their effectiveness, careful consideration of dosage is essential.

The optimal dispersant dosage is influenced by several factors, including the type and surface chemistry of the pigment, the nature of the liquid medium, the presence of other additives, and the desired end properties. Too little dispersant will result in inadequate wetting and flocculation, leading to poor color development and increased viscosity. Conversely, using too much dispersant can sometimes lead to over-stabilization, potentially affecting film properties, gloss, or even causing foaming.

A common starting point for determining dispersant dosage is based on the pigment content. For example, in many applications, the suggested dosage for inorganic pigments like titanium dioxide might range from 3-7% based on the pigment weight, calculated on a solid content basis. For organic pigments, this range can be wider, often from 10-50% of the pigment weight. These are general guidelines, and experimentation is often required to find the sweet spot for specific formulations. This trial-and-error is part of the process when you buy dispersants.

The goal is to use the minimum amount of dispersant necessary to achieve stable dispersion with optimal pigment wetting and deflocculation. This not only ensures the best color development and lowest millbase viscosity but also contributes to cost-effectiveness. Our high-performance dispersants are highly efficient, often requiring lower dosages compared to standard alternatives, which is a significant benefit when you buy dispersants.

At NINGBO INNO PHARMCHEM CO.,LTD., we advise conducting gradient tests to determine the ideal dosage for your specific application. This involves preparing several formulations with varying levels of dispersant and evaluating them for key parameters such as viscosity, color strength, and stability. Our technical team is available to provide guidance and support throughout this process, ensuring you get the most out of the dispersants you buy dispersants from us.

By mastering dispersant dosage, you can unlock the full potential of your pigments and enhance the overall quality and performance of your products. Partner with NINGBO INNO PHARMCHEM CO.,LTD. for expert chemical solutions and support.
