Chemi Tech Paint Dispersant Solution: Eliminating Flooding and Floatation for Enhanced Coating Performance

Issues such as flooding, floatation, flocculation, and inadequate color strength have long plagued coating manufacturers. These defects not only compromise appearance but also reduce product stability and market competitiveness. Targeting these challenges, Chemi Tech has developed high-performance paint dispersant solutions through years of technical innovation.  

Core Problem Analysis  

Flooding and floatation often result from uneven pigment dispersion or poor system compatibility, leading to irregular surface patterns. Flocculation causes pigment reagglomeration, adversely affecting storage and application properties.  

Four-Step Solution by Chemi Tech  

1. Precise Selection: Match dispersants to pigment polarity and resin systems—e.g., polymeric dispersants for carbon black, anionic types for inorganic pigments.  

2. Optimized Addition Process: Add dispersants before grinding to ensure firm anchoring on pigment surfaces, recommended at 0.2%-1.5% of pigment weight.  

3. Dispersion Parameter Control: Adjust grinding speed, duration, and medium ratio to achieve D90＜10μm particle distribution.  

4. Stability Validation: Evaluate dispersion stability via thermal storage (50℃×7d) and centrifugation tests.  

Case Reference  

An industrial coating manufacturer experienced severe whitening flooding in dark epoxy topcoats. By replacing original additives with Chemi Tech KMK-218 dispersant and extending grinding time to 45 minutes, the final product achieved uniform color tone and showed no flocculation or sedimentation after three months of storage.  

Chemi Tech dispersants excel in steric hindrance and wetting capabilities, compatible with alkyd, acrylic, epoxy, and other systems. We provide free samples and technical support to help enterprises upgrade coating performance.
