In the production and application of coatings and inks, the dispersion of pigments and fillers is a key factor determining final product performance. Poor dispersion leads to a series of troublesome problems: low grinding efficiency that wastes time and energy; poor finished gloss with dull or uneven color; and poor system stability that causes settling, re-coarsening, or performance decline after storage, directly affecting product quality and customer trust. These market pain points constrain efficiency improvement and product upgrading for many manufacturers. Facing these challenges, choosing an efficient and well-matched waterborne dispersant is crucial.
Chemi Tech has deep industry application expertise and is committed to providing professional-grade waterborne dispersant solutions. Our product series is designed for organic pigments of different polarities, carbon black, and inorganic fillers, and can significantly reduce grinding viscosity, improve grinding efficiency, and shorten production cycles. Their strong anchoring groups and steric hindrance effects ensure long-term stable dispersion of pigment particles, preventing flocculation and settling, thereby giving the final coating excellent color development, high gloss, and outstanding stability.
The specific solution steps are as follows:
Step one: precise selection. Based on your core pigment system (such as phthalocyanine blue, carbon black, or titanium dioxide) and final application performance requirements (such as gloss and resistance), our technical team will recommend the most suitable Chemi Tech dispersant model.
Step two: optimized addition. We provide a scientific reference range for dosage, usually based on pigment content, and recommend adding it at the early stage of the grinding process to achieve the best wetting and dispersion results.
Step three: process verification. In laboratory or pilot-scale settings, the improvement effect of the dispersant is verified by comparing slurry fineness, viscosity, and storage stability data before and after dispersion.
Step four: production application. The optimized formulation and process are smoothly introduced into the production line to achieve batch-to-batch product quality stability. Case sharing: a decorative paint manufacturer using a specific organic yellow pigment had long faced unstable tinting strength and rising viscosity after storage. After evaluation by the Chemi Tech technical team, a dedicated waterborne dispersant was selected for replacement. Following the adjustment, the pigment's viscosity during grinding decreased significantly, and grinding time was shortened by about 20%. The resulting tinted paint showed improved tinting strength with more vivid and saturated color. Accelerated storage tests showed greatly improved slurry stability with no re-coarsening, and the customer was satisfied with batch consistency. Chemi Tech believes that excellent dispersion is the cornerstone of excellent performance. We provide not only products but also technical support and customized services to tackle complex dispersion challenges, helping your products stand out in the market.
