General Purpose Dispersant BYK110 Automotive Intermediate Coating Excellent Cost-performance

Anjeka-6500A is a copolymer solution containing acidic groups, designed for pigment dispersion in solvent-borne medium and high polarity resin systems. It is suitable for both coatings and printing ink formulations, with particular strength in stabilizing titanium dioxide and inorganic pigments.

Steric Stabilization for Stable Dispersion
Anjeka-6500A deflocculates pigments through steric stabilization, creating durable barriers between pigment particles that resist flocculation over time. This results in consistent dispersion stability throughout storage and application.

High Gloss Achievement
The fine particle sizes produced through effective steric stabilization allow coatings to achieve higher gloss levels. Smooth, uniform pigment distribution is the foundation for reflective, professional-looking finishes.

Stronger Color Strength
Better dispersed pigments express color more effectively. Formulations using Anjeka-6500A show measurable improvement in color strength compared to poorly dispersed systems, allowing for more efficient pigment use.

Improved Transparency and Hiding Power
The additive enhances both transparency in transparent pigment systems and hiding power in opaque systems, depending on the formulation goal. This versatility makes it suitable for a wide range of coating types.

Significant Viscosity Reduction
Anjeka-6500A substantially reduces millbase viscosity during processing. This improves flow characteristics, makes dispersion easier to manage, and enables higher pigment loading without sacrificing application properties.

Reduced Haze in Electrostatic Applications
For inorganic pigmented coatings processed through electrostatic high rotation spraying, Anjeka-6500A effectively minimizes haze, delivering cleaner color development and more consistent finish appearance.

Anjeka-6500A is recommended for:

Coatings

• Solvent-borne coatings
• Solvent-free coatings
• Medium and high polarity resin systems

Printing Inks

• Solvent-borne ink systems
• Solvent-free ink systems

Ideal For

• Titanium dioxide stabilization
• Inorganic pigment systems
• Acid-catalyzed systems, including coil coatings

The anionic character of Anjeka-6500A makes it well suited for acid-catalyzed systems where many alternative dispersants may cause compatibility issues.

Dosage is calculated as supplied, based on pigment weight:

These are starting guidelines based on practical experience. Optimal dosage varies by pigment type, resin polarity, and performance targets. A series of laboratory tests is recommended to determine the best level for your specific formulation.

For best performance, add Anjeka-6500A to the millbase before introducing pigments. This ensures the dispersant is properly integrated into the resin system before high-shear processing begins, optimizing particle size reduction and dispersion stability.

Below 15 degrees C, separation and turbidity may occur during storage or transportation. This is normal and does not affect product quality. Simply heat to 30 to 40 degrees C and mix well before use. Performance is fully restored after proper heating and stirring.

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

Baking System Compatibility
Due to the high acid value of Anjeka-6500A, the additive may potentially accelerate cross-linking reactions in baking systems. Monitor viscosity changes during storage to ensure formulation stability remains within acceptable parameters.

Q: What is the difference between Anjeka-6500A and Anjeka 6402?
Both products use steric stabilization for inorganic pigments and share similar application areas. The main differences are in acid value (50-100 for 6500A vs 20-25 for 6402) and solvent system (customized for 6500A vs xylene for 6402). Anjeka-6500A offers higher acid value for stronger pigment affinity, while 6402 may offer broader formulation flexibility in certain systems.

Q: Can this product be used in solvent-free systems?
Yes. Anjeka-6500A is suitable for both solvent-borne and solvent-free coating and ink systems, offering formulation flexibility across different product lines.

Q: Why does the storage temperature threshold start at 15 degrees C rather than lower?
Anjeka-6500A has a higher acid value compared to some other dispersants, which makes it more sensitive to lower temperatures during storage. Maintaining storage above 15 degrees C helps preserve optimal handling characteristics.

Q: Will it work in acid-catalyzed coil coatings?
Yes. The anionic character of Anjeka-6500A makes it compatible with acid-catalyzed systems, including coil coating applications, where many dispersants are not suitable.

Q: What happens if the product appears turbid after cold storage?
Turbidity or separation below 15 degrees C is normal. Heat to 30 to 40 degrees C and stir thoroughly. Performance is fully restored and the product remains fully usable.

Q: How does the customized solvent system benefit my formulation?
The customized solvent system allows for better system matching with your specific resin and coating formulation, potentially improving compatibility and reducing the risk of solvent-related issues during processing or application.
