How do wetting dispersants achieve viscosity reduction and jetness improvement during grinding?

DH-6100 wetting dispersant provides efficient and stable dispersion solutions for various pigment systems by broadening its application scope and optimizing storage performance. As the industry pursues process simplification and cost optimization, its broad-spectrum compatibility is expected to help companies further upgrade their production processes.

In the coatings, inks, and pigment processing industries, dispersant performance directly impacts production efficiency and product quality. Current industry demand for dispersants focuses not only on dispersing efficiency but also on storage stability and multi-application applicability. Balancing dispersing effectiveness with long-term storage reliability through technological innovation has become a key issue in optimizing production processes.

Traditional dispersants have limited dispersing capabilities for materials such as organic pigments and carbon black, often requiring extended grinding times to improve fineness, resulting in increased energy consumption.

Some systems are prone to coarsening, sedimentation, or viscosity fluctuations after long-term storage, impacting product performance.

A single dispersant is difficult to adapt to pigments with varying polarity or surface properties, requiring frequent formulation adjustments and increasing process complexity.

Multi-component compound dispersants: While they can improve applicability, they increase formulation complexity and may lead to compatibility issues.

Excessive addition of additives: While they can shorten milling time, they can easily lead to abnormal system viscosity, affecting application and leveling.

Reliance on high-shear equipment: Over-reliance on mechanical forces for dispersion can damage the pigment structure and affect final color.

DH-6100 Wetting Dispersant: Balancing Efficiency and Stability with Broad-Spectrum Compatibility

Its molecular structure is compatible with a variety of materials, including organic pigments and carbon black. By reducing surface tension, it accelerates wetting and shortens milling time, particularly providing excellent viscosity reduction for carbon black systems.

By forming a stable pigment-resin interface, it reduces particle agglomeration and improves viscosity stability and color consistency after long-term storage.

During the carbon black dispersion process, DH-6100 reduces light scattering losses caused by insufficient dispersion, resulting in richer jet and surface gloss, and easing the difficulty of subsequent color adjustment.
