Inorganic Pigment Wetting & Dispersing Agent Solutions - Chemi Tech Efficient Additives Guide

Inorganic pigments often face dispersion challenges such as agglomeration, rapid sedimentation, and color inconsistency, leading to coarse surface finish and visible color deviation, which compromise product quality and production efficiency.  

To address these issues, Chemi Tech has developed a range of high-performance wetting and dispersing agents that reduce surface tension and enhance compatibility between pigments and binders, enabling rapid wetting and long-term dispersion stability.  

► 4-Step Solution:  

1. Type Selection—Match additive to pigment polarity, particle size, and system pH;  

2. Dosage Control—Accurate addition at 0.2%-2% of pigment mass;  

3. Dispersion Process Optimization—Pre-mix with pigment before high-shear blending with base material;  

4. Stability Verification—Monitor dispersion via microscopy and particle size analysis to prevent re-agglomeration or settling.  

► Case Example:  

A coating manufacturer encountered sedimentation and clumping in iron oxide red paste. After adding Chemi Tech KMK-312 wetting dispersant, dispersion time was reduced by 30%, the paste showed no stratification after three months of storage, and coating color difference ΔE ≤ 0.5. Customers reported significantly improved opacity and leveling.  

Chemi Tech additives offer broad compatibility with inorganic pigments like titanium dioxide, yellow iron oxide, and carbon black, supporting efficient dispersion and consistent quality.
