Water Based Wetting Dispersant LD-64190

Product Introduction

Water Based Wetting Dispersant LD-64190 is a high molecular weight block copolymer dispersant solution developed for pigment dispersion in water-based coating and ink systems. It helps improve pigment distribution, color development, gloss, transparency, and overall formulation stability, making it suitable for a wide range of aqueous pigment concentrates and industrial coating applications.

LD-64190 works by promoting pigment flocculation control through steric hindrance. By reducing the size of pigment aggregates and improving dispersion, it enhances color intensity and gloss while helping increase transparency and covering power. Its viscosity-reducing effect after dispersion also contributes to better leveling properties and allows higher pigment loading in suitable formulations.

Designed particularly for resin-free pigment concentrates, this dispersant can be used with pigment and water without requiring additional resin or cosolvent during grinding. It is suitable for inorganic pigments, titanium dioxide, organic pigments, and carbon black in different water-based systems.

Supplied by Yangzhou Lida Resin Co., Ltd., LD-64190 is developed for coating manufacturers, pigment concentrate producers, printing ink manufacturers, and industrial chemical formulators seeking reliable dispersing performance in aqueous formulations.

Key Features & Benefits

1. Effective Pigment Dispersion

The high molecular weight block copolymer structure helps stabilize pigment particles through steric hindrance, reducing aggregation and improving pigment distribution throughout the aqueous system.

2. Improved Color Development

By reducing pigment particle aggregation, LD-64190 helps improve color intensity and color performance, supporting consistent coloration in water-based coatings and inks.

3. Enhanced Gloss and Transparency

Improved pigment dispersion contributes to higher gloss and increased transparency, making the additive suitable for formulations where surface appearance and color clarity are important.

4. Improved Covering Power

The dispersant helps optimize pigment distribution, contributing to improved covering power and more efficient pigment utilization in suitable formulations.

5. Reduced System Viscosity

After dispersion, the formulation viscosity can decrease, helping improve flow and leveling properties while providing opportunities to increase pigment loading.

6. Suitable for Resin-Free Pigment Concentrates

LD-64190 is particularly recommended for producing stable resin-free pigment concentrates. A grinding formulation containing only pigment, LD-64190, and water can be used to achieve the desired dispersion properties.

7. Water-Based Formulation Compatibility

The product uses water as its solvent and contains no organic solvents. It is specifically designed for aqueous systems and is not intended for solvent-based formulations.

Adding Method & Processing Instructions

To achieve optimal dispersing performance, the addition sequence and mixing conditions should be properly controlled.

Method 1: Addition to Resin-Containing Systems

1. Prepare the grinding resin, cosolvent, or emulsion resin mixture according to the formulation.

2. Start stirring the mixture.

3. Slowly add LD-64190 under continuous agitation.

4. Ensure the additive is evenly distributed before introducing the pigments.

5. Add the selected pigments and proceed with the grinding and dispersion process.

Method 2: Preparation of Resin-Free Pigment Concentrates

For resin-free pigment concentrate production, the recommended procedure is:

1. Add the required amount of LD-64190 to water.

2. Mix thoroughly under stirring until the additive is evenly dispersed.

3. Gradually introduce the pigment into the mixture.

4. Continue grinding and dispersion until the required pigment fineness and dispersion properties are achieved.

5. Evaluate viscosity, color development, and storage stability before finalizing the formulation.

Processing Recommendations:

• Add the dispersant slowly under continuous stirring.

• Ensure uniform distribution before pigment addition.

• Adjust dosage according to pigment type and loading.

• Conduct laboratory compatibility and stability testing before large-scale production.

• Use only in water-based formulations.
