Anjeka6040:Hyperbranched Polymer Dispersant for Solvent-Based Coatings

Product Overview

ANJEKA-6040 is a polymer dispersant developed for solvent-based coatings and printing inks. Built on a hyperbranched polyester structure with imino anchoring groups, it delivers strong pigment wetting and stabilization across a wide range of organic and inorganic pigments.

From high-surface carbon black to organic colorants, ANJEKA-6040 helps formulators achieve higher gloss, cleaner color, and lower haze — while shortening grinding time and improving storage stability.

Key Benefits

Strong Pigment Wetting via Imino Anchoring
The hyperbranched polyester structure carries imino anchoring groups that adsorb firmly onto pigment surfaces. This creates a durable steric and electrostatic barrier that resists flocculation and keeps pigments evenly dispersed throughout production and storage.

Higher Gloss and Cleaner Color for Organic Pigments
ANJEKA-[CODE] improves the gloss and color vividness of organic pigments while reducing the haze caused by uneven dispersion. The result is brighter, more consistent color development in the finished film.

Superior Blackness for High-Surface Carbon Black
In high-surface-area carbon black dispersions, a key performance challenge is achieving deep, clean blackness without excessive viscosity. ANJEKA-[CODE] effectively enhances the blackness of carbon black systems, helping formulators reach deeper, richer blacks at workable viscosities.

Reduced Haze from Uneven Dispersion
By stabilizing pigments more uniformly, the additive minimizes the surface haze and fogging that come from poorly dispersed particles — particularly important for high-gloss and tinted systems.

Shorter Grinding Time, Higher Efficiency
Faster, more complete wetting shortens the milling cycle, improving production throughput and lowering energy and labor cost per batch.

Improved Storage Stability
Stable dispersion means less settling and re-agglomeration during storage, keeping batch-to-batch consistency high and reducing customer complaints.

Application Areas

It is recommended for:

• Solvent-based coatings dispersing organic and inorganic pigments
• Printing inks
• Stabilizing organic pigments, especially carbon black
• Systems based on polyester, polyurethane, and acrylic resin chemistries

Its broad resin compatibility makes it a versatile choice across multiple solvent-based product lines.

Recommended Dosage

Dosage is calculated as supplied, based on pigment weight:

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 it to the grinding base (millbase) before introducing pigments. This ensures the dispersant is properly positioned to anchor onto pigment surfaces before high-shear processing begins, maximizing dispersion efficiency and stability.

Storage and Handling

Stir thoroughly before use.

Below 0 degrees C, layering or turbidity may occur. This is normal and does not affect product quality. Heat to 30 to 40 degrees C and mix 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 advantage does the hyperbranched structure give over linear dispersants?
The hyperbranched polyester architecture provides multiple anchoring points and a compact steric shell around each pigment particle. This delivers stronger adsorption and more effective flocculation resistance than many linear dispersants, especially at higher pigment loading.

Q: Why is it particularly effective for high-surface carbon black?
High-surface-area carbon black is difficult to wet and tends to agglomerate, which limits achievable blackness and raises viscosity. The imino anchoring groups in ANJEKA-6040 adsorb strongly to the carbon surface, breaking agglomerates and enabling deeper blackness at manageable viscosity — which is why the recommended dosage for high-surface carbon black reaches 40% to 80%.

Q: Which resin systems is it compatible with?
ANJEKA-6040 is compatible with a wide range of coating resins, including polyester, polyurethane, and acrylic systems. This makes it suitable across most conventional solvent-based coating and ink formulations.

Q: How does it improve production efficiency?
By wetting and stabilizing pigments faster, the additive shortens the grinding phase and reduces rework from poor dispersion. Lower haze and better storage stability further reduce batch rejects and customer complaints.

Q: What happens if the product separates during cold storage?
Separation or turbidity below 0 degrees C is normal. Heat to 30 to 40 degrees C and stir thoroughly. The product returns to its normal appearance and performance is fully preserved.

Q: Can it be used in printing inks?
Yes. ANJEKA-6040 is recommended for printing ink applications, particularly for stabilizing organic pigments and carbon black where deep color and clean dispersion are required.
