In the formulation of high-quality water-based coatings and inks, achieving optimal pigment dispersion is a critical challenge. Poor dispersion can lead to issues such as reduced color strength, lower gloss, settling, and instability, significantly impacting the final product's performance and appearance. The need for effective dispersing agents that can wet, separate, and stabilize pigment particles efficiently is paramount.

Responding to this industry need, NINGBO INNO PHARMCHEM CO.,LTD. offers DS-195L, a high-performance liquid dispersant specifically designed for water-based pigment systems. DS-195L is a solution of high molecular polymers featuring pigment anchoring groups, engineered to provide exceptional dispersion properties for a wide range of pigments, including challenging inorganic pigments like Titanium Dioxide, as well as iron oxides, carbon black, and various organic pigments.

The key characteristics of DS-195L contribute directly to improved formulation performance. It provides good wetting effects to both pigments and fillers, ensuring that powder agglomerates are quickly and effectively penetrated by the aqueous phase. Following wetting, DS-195L facilitates outstanding deflocculation, breaking down pigment aggregates into finer primary particles. Furthermore, its unique structure imparts a powerful charge repulsion property to the dispersed particles, preventing them from re-agglomerating and ensuring long-term millbase stability. This is crucial for maintaining consistent color development and preventing settling over time.

Utilizing DS-195L in grinding systems offers significant advantages. It effectively reduces the viscosity of the millbase, allowing for higher pigment loading and more efficient grinding operations. This leads to improved color development and dispersion fineness, enhancing the overall quality and performance of the final coating or ink. Notably, DS-195L is also APEO-free, aligning with increasing environmental and health regulations.

The versatility of DS-195L makes it suitable for a broad spectrum of applications within the water-based sector. Recommended uses include architectural coatings, wood and furniture coatings, automotive coatings, can coatings, anticorrosive paints, leather coatings, and water-based inks. Its efficacy has been demonstrated across various pigment types, providing formulators with a reliable tool for achieving superior dispersion results.

Operational recommendations for DS-195L suggest adding the dispersant into water before incorporating resin and pigment to ensure optimal performance. Suggested dosages vary depending on the pigment type, typically ranging from 10-50% based on the solid content of organic pigments and 3-7% based on the solid content of inorganic pigments like titanium dioxide. While DS-195L provides excellent wetting, the addition of compatible wetting agents and defoamers may be beneficial for specific formulations or challenging powders.

DS-195L is supplied as a yellow transparent liquid with a content of 40% in water. For storage, it should be sealed and kept in a dry, cool, well-ventilated place at room temperature, offering a typical shelf life of 24 months when stored properly. Packaging options are available to suit different needs, from smaller containers for testing to larger drums for bulk production.
