A Super Viscosity-Reducing Dispersant Specifically Designed for Inorganic Pigments

In the industrial coatings sector, where high production efficiency and excellent film appearance are paramount, the grinding and dispersion process is a critical step determining product performance and cost. Inorganic pigments, especially titanium dioxide, often lead to a sharp increase in grinding paste viscosity due to their high surface energy, resulting in higher energy consumption and potential subsequent film defects such as insufficient gloss, haze, and flooding/floating. Selecting an efficient wetting and dispersing agent is the starting point for solving these challenges. Anjeka 6860, a wetting and dispersing agent specifically designed for stabilizing inorganic pigments, is becoming a reliable choice for many engineers facing stringent process requirements, thanks to its excellent viscosity reduction, broad system compatibility, and outstanding storage stability.

I. Core Advantages: Why is 6860 the "Inorganic Pigment Expert"?
Anjeka 6860 is a wetting and dispersing agent containing an acidic group copolymer solution. Its anionic nature gives it excellent affinity for the surface of inorganic pigments, allowing for rapid wetting and anchoring of pigment particles, preventing their re-flocculation through steric hindrance. This mechanism directly delivers three core advantages:

Powerful Viscosity Reduction, Boosting Efficiency: Significantly reduces grinding paste viscosity, making high-solids and solvent-free systems easier to grind and pump, directly reducing energy consumption and production time.
Optimized Optical Properties: Fully dispersed titanium dioxide maximizes its hiding power and tinting strength, thereby improving film gloss and effectively reducing haze caused by poor dispersion, resulting in a clearer, more vibrant coating appearance.
Excellent Storage Stability: A stable dispersion state means the colorant is less prone to re-coarsening and settling during long-term storage, with minimal changes in viscosity and fineness, ensuring batch-to-batch consistency and reproducibility.

II. Broad Applicability: Beyond Traditional Coatings
The applicability of 6860 extends far beyond traditional perceptions, as its design allows it to handle various advanced and specialty systems:

Responding to Environmental Trends: Suitable for high-solids and solvent-free coatings, and the product is zero-VOC, meeting increasingly stringent environmental regulations.
Mainstay in Industrial Coatings: Performs excellently in industrial fields such as coil coatings, automotive coatings, and anti-corrosion coatings, particularly suitable for acid-catalyzed systems (e.g., coil coatings).
Preferred for Resin-Free Colorants: Can successfully prepare storage-stable inorganic pigment resin-free colorants in glycol ether solvents like ethylene glycol monobutyl ether and benzyl alcohol, as well as UV-curing monomers like TPGDA and NPGDA, providing flexible coloring solutions for UV inks and specialty coatings.
Breakthrough in Functional Systems: Tests show that 6860 exhibits excellent viscosity reduction performance in photovoltaic aluminum paste; in high-filler, high-viscosity systems like polyaspartic coatings, it balances viscosity reduction and anti-settling needs well.

III. Practical Verification: Data Speaks, Results Are Visible
Our laboratory and application cases provide strong evidence:

In Coil Coatings, a gray paint made from a white paste using 6860 to disperse titanium dioxide and a black paste using 6042A to disperse carbon black showed a rub-out color difference (ΔE) of only 0.3, demonstrating its excellent pigment stability and anti-flooding ability.
In Resin-Free Colorants, grinding titanium dioxide with 6860 in n-butanol resulted in a fineness maintained below 10μm after 7 days of heat storage, with a slow increase in viscosity, showing outstanding long-term stability.
In a demanding polyaspartic white paste test, 6860 provided effective viscosity reduction (viscosity 2545 mPa.s) while achieving the best anti-settling effect (0.2 settlement after 3 days of heat storage), demonstrating its comprehensive performance in complex systems.

IV. Usage Guidelines: How to Maximize the Effectiveness of 6860?
To achieve optimal results, we recommend:

Addition Order: During the grinding stage, first add Anjeka 6860 to the resin or solvent, mix thoroughly, and then add the pigment to ensure it fully wets the pigment surface.
Recommended Dosage: For inorganic pigments, the recommended addition is 2%-5% based on the total pigment weight; for titanium dioxide, the suggested range is 1%-3%. The specific optimal dosage should be determined through testing based on your specific resin, solvent, and pigment system.
Combination Suggestions: For complex color systems containing organic pigments or carbon black, it is recommended to use 6860 in combination with dispersants like Anjeka 6042A, which are good at handling organic pigments, to more effectively solve flooding/floating issues.

With its exceptional dispersing power for inorganic pigments, especially titanium dioxide, Anjeka 6860 is helping more and more companies solve pain points such as high grinding viscosity, insufficient gloss, and poor storage stability. Whether improving existing product performance or developing new high-solids, solvent-free, or UV-curable products, it is a trustworthy starting point.
