Anjeka 6402 A Versatile Dispersant Solving Multiple Challenges in Industrial Coatings

Formulators of industrial coatings, such as epoxy floor coatings, acrylic baking enamels, and polyester/alkyd anticorrosive paints, constantly grapple with the trade-offs of high filler loading. Increased filler content often leads to undesirable consequences: skyrocketing grinding viscosity, poor storage stability with hard settlement, and color matching issues like flooding and floating. Is there a single dispersant that can address these interconnected problems across different resin systems? Anjeka 6402 presents itself as a compelling candidate.

Epoxy floor coatings require high loadings of fillers like calcium carbonate for build, hardness, and cost-effectiveness. The primary challenges are achieving a grindable viscosity and preventing filler settlement during storage.

• Role of Anjeka 6402: It acts as a powerful wetting and dispersing agent for inorganic fillers. By effectively breaking down agglomerates, it significantly reduces the mill base viscosity, enabling higher solid content and faster grinding cycles.
• Problem Solved: Improved production efficiency and reduced risk of hard packing. When used in conjunction with anti-settling agents like Anjeka 4410, it contributes to a robust suspension system, ensuring consistent application properties from the first can to the last.

For colored industrial baking finishes, a stable, well-dispersed white base (often titanium dioxide paste) is crucial for accurate and consistent tinting.

• Role of Anjeka 6402: When used to disperse titanium dioxide and other inorganic pigments/extenders in acrylic baking systems, Anjeka 6402 provides excellent viscosity reduction and dispersion stability.
• Problem Solved: This stability minimizes interference during tinting, effectively reducing the tendency for flooding and floating. The result is superior color development, minimal batch-to-batch color shift, and improved storage color stability, which is critical for meeting stringent quality standards.

These systems demand dispersants that perform well in both high-filler primer/mid-coats and in universal pastes for tinting.

• Role of Anjeka 6402: It demonstrates broad compatibility across polyester, alkyd, and their corresponding polyurethane (2K-PU) systems. It can be used effectively for dispersing fillers in high-build primers. Notably, feedback indicates that white pastes prepared with Anjeka 6402 in 2K-PU systems exhibit excellent tinting acceptance and resistance to floating, providing a reliable foundation for topcoat color.
• Problem Solved: Simplifies formulation and inventory by serving as a universal dispersant for inorganic components. Enhances the overall color fidelity and uniformity of the final anticorrosive coating system.

• Reduces Grinding Viscosity: Enables higher filler loading and improves production throughput.
• Enhances Storage Stability: Helps prevent the settlement of inorganic fillers and pigments.
• Improves Color Acceptance: Mitigates floating and flooding in tinting systems, ensuring color uniformity.
• Offers Broad Compatibility: Functions effectively across epoxy, acrylic, polyester, and alkyd resin systems, simplifying selection.
