Modified Acrylate Dispersing Agent Low Dosage For High Solid System Enhance Matting Efficiency And Orientation

Anjeka-6820 Dispersant for UV-Curable and Solvent-Free Systems

Product Overview

Anjeka-6820 is a modified acrylic copolymer solution specifically developed for solvent-free and UV-curable coating and ink systems. It delivers excellent dispersion performance across a wide range of resin chemistries and is also suitable for pigment concentrate production.

This versatile dispersant brings particular value to UV-curable formulations where matting agent dispersion is critical — combining broad compatibility, viscosity reduction, and matting efficiency enhancement in one product.

Key Benefits

Specialized for Solvent-Free and UV-Curable Systems
Anjeka-6820 is engineered for the unique requirements of solvent-free and UV-curable formulations. Its modified acrylic structure provides effective dispersion performance where conventional dispersants may be incompatible or less effective.

Excellent Matting Agent Dispersion
One of Anjeka-6820’s most distinctive strengths is its performance with silica-based matting agents in solvent-free UV systems. At low dosage levels, it improves matting efficiency and promotes better orientation of matting agents, resulting in more consistent and effective matte finishes.

Strong Viscosity Reduction
The additive substantially lowers system viscosity during processing, improving flow characteristics and making high-solid formulations easier to handle and apply.

Broad Resin Compatibility
Anjeka-6820 demonstrates good compatibility with a wide range of resin systems, making it a versatile choice for manufacturers with diverse product lines. It performs reliably across high-solids systems, wood coatings, industrial coatings, and more.

Pigment Concentrate Production
The additive is suitable for manufacturing stable pigment concentrates, offering formulation flexibility and supporting more efficient color production workflows.

Application Areas

Special Recommendations:

• Industrial coatings
• Automotive coatings
• Printing inks

Also Suitable For:

• Architectural coatings
• Wood and furniture coatings
• Can coatings
• Any high-solids resin system

Recommended Dosage

Dosage is calculated as dispersant solid content to pigment ratio:

These are empirical starting guidelines. Optimal dosage varies by pigment type, 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-6820 to the formulation during the grinding phase before introducing pigments. This ensures the additive is properly integrated into the resin system before high-shear processing begins, maximizing dispersion efficiency and matting agent performance.

Storage and Handling

Store in a cool, dry place. Mix 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 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 makes Anjeka-6820 different from other dispersants?
Anjeka-6820 is specifically formulated for solvent-free and UV-curable systems, where many conventional dispersants struggle with compatibility or fail to effectively disperse matting agents. Its modified acrylic structure bridges the gap between broad resin compatibility and the specialized demands of UV systems.

Q: Why is matting agent dispersion important in UV coatings?
In UV-curable matte finishes, the silica matting agent must be uniformly dispersed and properly oriented throughout the coating to achieve consistent gloss reduction. Poor dispersion leads to uneven matte appearance, gloss variation, and poor texture. Anjeka-6820 addresses this directly.

Q: Can it be used in non-UV solvent-free systems?
Yes. While it excels in UV systems, Anjeka-6820 is compatible with a wide range of resin systems, including high-solids conventional coatings. It is a versatile choice across industrial, automotive, and architectural coating applications.

Q: How does it help with viscosity reduction?
The modified acrylic structure reduces inter-particle interactions during dispersion, lowering system viscosity. This makes high-solids formulations easier to process and apply, and can support higher pigment loading.

Q: Is it suitable for pigment concentrate production?
Yes. Anjeka-6820 can be used to manufacture stable pigment concentrates, giving manufacturers flexibility in color production workflows and inventory management.

Q: What happens if the product separates during cold storage?
Separation or turbidity 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.
