ANJEKA-6810 CPT-Based Block Copolymer Dispersant

Product Overview

ANJEKA-6810 is a block copolymer dispersant developed using CPT (Controlled Polymerization Technology), designed for solvent-based and solvent-free coating and ink systems. It delivers excellent dispersion performance with broad compatibility across a wide range of resin chemistries, making it especially recommended for universal pigment concentrate applications.

The CPT-based block copolymer structure provides a controlled, predictable architecture that delivers consistent pigment stabilization — batch after batch, formulation after formulation.

Key Benefits

CPT-Enabled Block Copolymer Architecture
The controlled polymerization process produces a block copolymer with precisely arranged pigment-affinitive groups. This structured design gives ANJEKA-6810 more predictable and consistent stabilization behavior compared to conventional random copolymers.

Steric Stabilization for Deflocculation
ANJEKA-6810 deflocculates pigments through steric hindrance — creating a durable physical barrier around each particle that resists reagglomeration throughout production, storage, and application.

Higher Gloss from Fine Particle Size
Effective deflocculation produces finer, more uniform pigment particles. Finer particles scatter light more evenly, resulting in higher measured gloss in the finished coating or ink.

Stronger Color Strength
Better dispersed pigments express color more efficiently. Formulations using ANJEKA-6810 show measurable improvements in color strength, allowing for more effective pigment utilization and potential cost savings.

Enhanced Transparency and Hiding Power
Transparent pigments develop greater clarity, while opaque pigments achieve better hiding power — depending on your specific formulation goals.

Reduced Viscosity for Improved Flow
Lower system viscosity during processing improves flow characteristics, simplifies production, and supports higher pigment loading in colorant concentrates.

High Solids Compatibility
With 70% active content and a broad resin profile, ANJEKA-6810 is particularly suited for high-solids systems where every component must contribute efficiently without diluting performance.

Universal Pigment Concentrate Production
A standout application for ANJEKA-6810 is in universal pigment concentrate formulations, where broad compatibility and consistent stabilization across multiple pigment types are essential for reliable, multi-purpose colorants.

Application Areas

Special Recommendations:

• Industrial coatings
• Automotive coatings

Also Recommended For:

• Architectural coatings
• Printing inks
• High-solids systems
• Universal pigment concentrate production

Resin Compatibility:
ANJEKA-6810 demonstrates strong compatibility with a wide range of coating resins, including alkyd, cellulose, chlorinated rubber, epoxy, polyurethane, polyester, and acrylic systems.

Recommended Dosage

Dosage is calculated as dispersant solid content to pigment ratio:

These are empirical starting guidelines. Optimal dosage varies by pigment type, surface area, resin system, and performance targets. A series of tests is recommended to determine the best level for your specific formulation.

How to Add

For best performance, add ANJEKA-6810 to the formulation during the grinding phase before introducing pigments. This ensures the dispersant is properly positioned to wet pigment surfaces before high-shear processing begins, maximizing deflocculation efficiency and final dispersion quality.

Storage and Handling

Store in a cool, dry place. Stir thoroughly before use.

Below 0 degrees C, layering or turbidity may occur. This is normal and does not affect product quality. Simply heat to 20 degrees C and stir thoroughly until uniform. Performance is fully restored after proper heating and stirring.

Recommended storage period: do not exceed 12 months from date of manufacture.

Frequently Asked Questions

Q: What does “CPT technology” mean in a dispersant?
CPT (Controlled Polymerization Technology) produces a block copolymer with a precisely arranged molecular architecture — rather than a random distribution of functional groups. This control gives ANJEKA-6810 more predictable adsorption behavior onto pigment surfaces and more consistent steric stabilization, resulting in better batch-to-batch reproducibility.

Q: How is ANJEKA-6810 different from conventional hyperbranched dispersants?
Hyperbranched dispersants rely on a highly branched, tree-like structure. ANJEKA-6810 uses a block copolymer architecture enabled by CPT, which sequences pigment-affinitive blocks in a controlled pattern. This can offer more consistent performance and broader compatibility across diverse pigment types and resin systems.

Q: Why is it recommended for universal pigment concentrates?
Universal pigment concentrates need to work across multiple resin systems and pigment types without reformulation. ANJEKA-6810’s broad resin compatibility (alkyd, epoxy, PU, acrylic, and more) combined with its strong performance across inorganic, organic, and carbon black pigments makes it an ideal single dispersant choice for this application.

Q: What does 70% active content mean for my formulation?
With 70% active content, ANJEKA-6810 delivers concentrated dispersing performance. The remaining 30% is xylene solvent, which is typical for solvent-based systems and compatible with most coating and ink formulations. This concentration level is well-suited to high-solids systems where efficient active delivery is important.

Q: How does it perform in high-solids systems?
ANJEKA-6810 is particularly suited for high-solids formulations due to its high active content, strong compatibility, and ability to reduce viscosity during processing — all of which support higher solids loading without compromising application properties.

Q: Can it be used in solvent-free systems?
Yes. ANJEKA-6810 is suitable for both solvent-based and solvent-free systems, providing formulation flexibility across different product lines.

Q: What happens if the product becomes turbid during cold storage?
Turbidity or layering below 0 degrees C is normal. Heat to 20 degrees C and stir thoroughly. The product returns to its normal appearance and performance is fully preserved.
