Description
Product Overview
Dispersant LD-6406 is a high-performance pigment dispersant developed for solvent-containing and solvent-free water-based coating systems. Based on block copolymer alkyl ammonium salt with acid groups, it effectively prevents pigment flocculation through steric stabilization and charge control, improving coating stability and overall performance.
Designed especially for inorganic pigments such as titanium dioxide, Dispersant LD-6406 helps achieve better pigment dispersion, higher gloss, improved tinting strength, enhanced transparency, and optimized hiding power. Its solvent-free formulation makes it an ideal choice for low VOC and VOC-free coating applications.
Product Features
Excellent Pigment Deflocculation Performance
Dispersant LD-6406 provides effective steric stabilization for pigment particles, preventing unwanted aggregation and maintaining uniform pigment distribution in coating formulations.
Improved Gloss & Color Performance
By maintaining fine and stable pigment particle size, the dispersant helps improve surface gloss, color development, tinting strength, and coating appearance.
Enhanced Transparency & Hiding Power
The optimized dispersion effect allows pigments to achieve better optical performance, improving transparency and hiding capability in finished coatings.
Reduced System Viscosity
The product effectively reduces abrasive viscosity, improving coating flow, leveling performance, pigment loading capacity, and processing efficiency.
Solvent-Free & Low VOC Solution
With a solvent-free composition, Dispersant LD-6406 supports environmentally friendly coating formulations and is suitable for low VOC and VOC-free systems.

Performance Benefits in Coating Systems
When added to coating formulations, Dispersant LD-6406 helps maintain stable pigment dispersion and prevents pigment co-flocculation caused by unequal particle charges. The smaller and more evenly distributed pigment particles contribute to improved coating appearance, higher gloss, stronger color expression, and better application performance.
Its excellent viscosity reduction capability allows formulators to achieve smoother processing, improved leveling, and higher pigment content while maintaining coating stability.
