Struggling with Dispersion in Coatings & Inks? Chemi Tech's Aqueous Dispersant Solutions

In the production and application of coatings and inks, the dispersion of pigments and fillers is a critical step determining the final product performance. Poor dispersion leads to a series of headaches: low grinding efficiency of pastes, wasting time and energy; inferior gloss of finished products, dark or uneven color; poor system stability, causing sedimentation, re-coarsening, or performance degradation after storage, directly impacting product quality and customer trust. These market pain points constrain the efficiency improvement and product upgrade for many manufacturers. Facing these challenges, selecting an efficient and compatible aqueous dispersant is essential. 

Chemi Tech, with deep industry expertise, is dedicated to providing professional-grade aqueous dispersant solutions. Our product series are designed for organic pigments, carbon black, and inorganic fillers with different polarities. They 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 imparting excellent color development, high gloss, and outstanding stability to the final coating. 

The specific solution steps are as follows: Step 1: Precise Selection. Based on your core pigment system (e.g., phthalocyanine blue, carbon black, titanium dioxide) and final application performance requirements (e.g., gloss, resistance), our technical team will recommend the most suitable Chemi Tech dispersant type. Step 2: Optimized Addition. We provide scientific addition amount reference ranges, typically based on pigment weight, and recommend adding it in the early grinding stage for optimal wetting and dispersion effects. Step 3: Process Verification. In the laboratory or pilot stage, verify the improvement of the dispersant by comparing data such as paste fineness, viscosity, and storage stability before and after dispersion. Step 4: Production Application. Smoothly introduce the optimized formula and process into the production line to achieve batch-to-batch stability of product quality. Case Study: A decorative paint manufacturer faced persistent issues with unstable tinting strength and increased viscosity after storage when using a specific type of organic yellow pigment. After evaluation by the Chemi Tech technical team, a dedicated aqueous dispersant was recommended. After adjustment, the viscosity of the pigment during the grinding stage significantly decreased, and grinding time was reduced by approximately 20%. The produced color paint showed improved tinting strength, with more vibrant and饱满的颜色. Accelerated storage tests indicated a substantial improvement in paste stability, with no re-coarsening observed, and the customer expressed satisfaction 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.
