Inorganic Pigment Wetting Dispersant Professional Solution - Chemi Tech Efficient Additives

In the application of inorganic pigments, poor dispersion stability, easy sedimentation, and insufficient coloring power are common challenges. These issues not only affect product appearance but also increase production costs and reduce efficiency. Addressing these market needs, Chemi Tech has developed a series of high-efficiency wetting dispersants that significantly enhance the dispersion and stability of pigment systems.

Common problems include: difficulty in wetting pigments, re-agglomeration after dispersion, sedimentation during storage, and inconsistent color development. These often stem from high surface energy and polarity of pigments, as well as improper dispersion processes or additive selection.

Chemi Tech's solution involves four steps:

Step 1: Analyze pigment type and system polarity to select the appropriate dispersant type;

Step 2: Determine the optimal dosage, typically 0.2%-2% of pigment mass;

Step 3: Employ suitable dispersion equipment and processes, such as high-speed stirring or grinding;

Step 4: Verify dispersion effectiveness through indicators like fineness, viscosity, and stability.

A coatings manufacturer faced sedimentation and color difference issues with gray exterior wall coatings. By using Chemi Tech dispersant L-108 at 0.8% dosage during pigment feeding and high-speed dispersion, pigment particle size was controlled below 15μm. After 30 days of storage, no sedimentation occurred, color consistency improved significantly, and production costs reduced by approximately 5%.

Chemi Tech dispersants feature low dosage, broad applicability, and good compatibility, suitable for various inorganic pigments such as iron oxide, titanium dioxide, and carbon black systems, helping customers enhance product quality and production efficiency.
