Description
Product Introduction
Waterborne Super Dispersant for Pigment & Filler LD-6408 is a high-performance water-based dispersant developed for the efficient dispersion and stabilization of pigments and fillers in aqueous systems. Its comb-like molecular structure consists of a polyacrylic acid-based main chain and specially optimized polymer side chains.
The molecular structure enables LD-6408 to strongly adsorb onto the surfaces of different pigment and filler particles. By generating electrostatic repulsion and forming an effective steric barrier around the particles, it helps prevent particle aggregation and provides excellent dispersion efficiency and long-term stability.
LD-6408 is suitable for a wide variety of inorganic pigments and fillers and demonstrates particularly effective dispersion performance with calcium carbonate and titanium dioxide. It can be considered for waterborne coating and related formulation systems where good pigment wetting, dispersion, stability, and processing consistency are required.
Key Product Features
1. Advanced Comb-Like Molecular Structure
LD-6408 features a comb-like polymer structure with a polyacrylic acid-based main chain and optimized special polymer side chains. This structure supports strong interaction with pigment and filler surfaces.
2. Excellent Pigment and Filler Dispersion
The dispersant can effectively adsorb onto particle surfaces, helping separate pigment and filler particles and reduce aggregation in aqueous formulations.
3. Electrostatic and Steric Stabilization
LD-6408 combines electrostatic repulsion with steric hindrance. The resulting barrier around particle surfaces helps maintain dispersion stability and reduces the tendency of particles to re-agglomerate.
4. Particularly Effective for Calcium Carbonate and Titanium Dioxide
The product is suitable for many inorganic pigments and fillers, with particularly good dispersion performance for calcium carbonate and titanium dioxide.
5. Good Water Solubility
LD-6408 is water-soluble, making it convenient for use in water-based formulations and aqueous coating systems.
6. Good Organic Solvent Tolerance
The dispersant demonstrates good compatibility and tolerance with selected organic solvents, including alcohols and glycol ethers, providing greater formulation flexibility.
7. Long-Term Dispersion Stability
By providing both electrostatic and steric stabilization, LD-6408 helps maintain a stable pigment and filler dispersion during storage and application.

Recommended Applications
Waterborne Coatings
LD-6408 can be incorporated into water-based coating formulations to improve the dispersion of pigments and fillers and support formulation stability.
Inorganic Pigment Dispersion
The product is designed for various inorganic pigments and is particularly suitable for systems containing calcium carbonate and titanium dioxide.
Filler Dispersion
LD-6408 can help disperse mineral fillers efficiently in aqueous formulations, supporting uniform particle distribution and stable formulations.
Carbon Black and Nano-Sized Pigments
For carbon black and nano-sized pigments or fillers, LD-6408 can be used at a higher dosage range to achieve the required dispersion performance.
Recommended Dosage
The appropriate dosage depends on the pigment or filler type, surface characteristics, formulation composition, and desired dispersion performance.
Typical dosage guidelines are:
-
General pigments and fillers: 0.5%–1% based on the pigment/filler amount
-
Carbon black and nano-sized pigments/fillers: 30%–60% based on the pigment/filler amount
These dosage ranges are general recommendations. The optimum addition level should be established through laboratory testing according to the specific formulation and application requirements.
How LD-6408 Works
After addition to an aqueous pigment or filler system, LD-6408 adsorbs onto particle surfaces through its polymer structure. The adsorbed dispersant promotes separation between particles through electrostatic repulsion while its polymer side chains contribute steric stabilization.
This combined stabilization mechanism helps minimize particle aggregation and supports a more uniform dispersion. As a result, LD-6408 can contribute to improved dispersion stability in water-based formulations.
Compatibility
LD-6408 is water-soluble and designed primarily for aqueous systems. It also offers good tolerance to selected organic solvents, including:
-
Alcohols
-
Glycol ethers
Formulators should conduct compatibility and stability testing before commercial production, particularly when combining LD-6408 with new resin systems, pigments, fillers, additives, or solvents.
