High-Performance Polymer Dispersant Solutions | Chemi Tech Solves Your Particle Agglomeration Challenges

In many production processes, the dispersion effect of powder materials such as pigments and fillers directly impacts the quality of the final product. Agglomeration, settling, uneven gloss, and performance instability are common challenges that not only reduce production efficiency but can also lead to batch variations and cost waste. Traditional dispersion methods often fall short, struggling to achieve uniform stability at the microscopic level. Chemi Tech specializes in the research, development, and application of polymer dispersants, committed to providing chemical solutions that address dispersion problems at their root for our clients.

Our solution is based on polymer design principles. Chemi Tech dispersant molecules contain specific anchoring groups and solvating chain segments. The anchoring groups firmly adsorb onto the surface of particle powders, while the extending solvating chains form an effective spatial barrier in the medium, preventing particles from re-agglomerating through powerful steric hindrance. This mechanism significantly reduces system viscosity, increases solid content, and imparts excellent long-term storage stability to the product.

The implementation steps are clear and specific. First, our technical team conducts a detailed diagnosis of your system, analyzing powder properties, medium type, and process conditions. Subsequently, we select or customize the most compatible polymer dispersant product. During the application phase, we recommend pre-adding the dispersant to the grinding medium or liquid phase to ensure complete dissolution before introducing the powder for dispersion and grinding. This sequence maximizes its wetting and stabilizing effectiveness. Finally, dispersion results are verified through methods like particle size analysis and stability testing to ensure the desired objectives are met.

For instance, a coatings client faced issues of low tinting strength, slow grinding efficiency, and re-coarsening after storage when producing high-concentration color pastes. After adopting a block copolymer dispersant recommended by Chemi Tech, the grinding time for the color paste was reduced by approximately 30%, tinting strength improved noticeably, and the prepared paste maintained a uniform particle size distribution even after several months of storage. This successfully resolved their pain points of color difference between batches and stability fluctuations.
