Wetting And Dispersing Additive To Acid Catalytic System Coil Coating Stabilize TiO2 BYK111

Anjeka-6860 is a wetting and dispersing additive developed for solvent-borne, solvent-free coatings, and printing ink systems. It is specifically effective at stabilizing inorganic pigments, particularly titanium dioxide, and delivers significant viscosity reduction in grinding formulations.

With 100% active content and no solvent carriers, Anjeka-6860 is well suited for high solids and solvent-free formulations where every gram of additive contributes directly to dispersion performance.

Highly Effective for Titanium Dioxide
Anjeka-6860 stabilizes titanium dioxide particularly well, delivering measurable improvements in final coating quality. TiO2-containing formulations show increased gloss, reduced haze, and more consistent color development.

Significant Viscosity Reduction
One of the most practical benefits of Anjeka-6860 is its ability to substantially lower millbase viscosity during dispersion. Lower viscosity means easier processing, faster throughput, and more efficient pigment incorporation.

Broad System Compatibility
The additive is suitable for solvent-borne, solvent-free, and high solids coating systems, making it a versatile choice for manufacturers with multiple product lines.

Anionic Chemistry for Acid-Catalyzed Systems
Due to its anionic character, Anjeka-6860 is well suited for acid-catalyzed systems, including coil coatings, where many other dispersants may cause incompatibility or instability.

Special Recommendations:

• Industrial coatings
• Automotive coatings
• Coil coatings
• Anti-corrosion coating systems

Also Suitable For:

• High solids coatings
• Solvent-free coatings
• Printing inks

Dosage is calculated as supplied, based on pigment weight:

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.

For best performance, add Anjeka-6860 to the grinding base (millbase) before introducing pigments. This ensures the additive is properly integrated into the resin system before high-shear processing begins, maximizing wetting efficiency and dispersion stability.

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

Store in airtight containers to maintain product integrity. Do not return pre-diluted product to original storage containers.

Pre-Dilution Handling
After pre-dilution, the product should not be re-stored in its original form. Prepare only the amount needed for immediate use, and keep the original container tightly sealed to preserve the undiluted material.

Q: What is the difference between Anjeka-6860 and Anjeka-6111?
Both products are dispersants for inorganic pigments and share similar application areas. The main difference is in acid value: Anjeka-6860 has an acid value of 50-150, while Anjeka-6111 is higher at 150-250. Anjeka-6860 may offer better compatibility with certain resin systems, while Anjeka-6111 provides stronger pigment affinity for more difficult-to-disperse materials. Testing both in your formulation is recommended.

Q: How does it reduce millbase viscosity?
The additive’s copolymer structure with acidic groups effectively wets pigment surfaces, reducing the inter-particle forces that contribute to viscosity. This allows more efficient processing and higher pigment loading without excessive viscosity buildup.

Q: Is it suitable for solvent-free systems?
Yes. With 100% active content and no solvent carrier, Anjeka-6860 is well suited for solvent-free and high solids coating formulations where inert diluents are undesirable.

Q: Why is the acid value important?
The acid value reflects the concentration of acidic groups in the copolymer, which drive pigment affinity and adsorption. Anjeka-6860’s moderate acid value (50-150) balances strong pigment interaction with broad resin compatibility.

Q: What happens if I pre-dilute the product?
Pre-diluted material should not be returned to the original container or re-stored. Prepare only the amount needed for immediate use to maintain product quality.
