ANJEKA-4561 Effect Pigment Orientation Agent for Water-Based Coatings

Product Overview

Anjeka-4561 is a modified polyamide salt developed for water-based coating systems. It improves the orientation of effect pigments — such as metallics and pearlescents — and provides anti-settling performance throughout storage and application.

In water-based automotive and industrial coatings, where visual appearance is a primary quality signal, Anjeka-4561 helps ensure that every batch delivers consistent color development, brightness, and visual uniformity on the finished part.

Key Benefits

Improved Effect Pigment Orientation
Anjeka-4561 promotes more uniform and controlled orientation of effect pigments within the coating film. This reduces cloudiness, color spots, and visible color variation across large or complex surfaces — delivering the even, high-quality appearance that automotive and premium industrial coatings demand.

Enhanced Brightness and Visual Impact
By improving the rheological behavior of effect pigment slurries — including those formulated without co-solvent — Anjeka-4561 helps maximize the visual brightness and flop effect of metallic and pearlescent pigments.

Minimal Impact on System Viscosity
Unlike polyurethane thickeners or acrylic thickeners, Anjeka-4561 has a relatively small effect on the overall viscosity of the coating system. This gives formulators better control over application properties without sacrificing anti-settling performance.

Strong Thixotropic Anti-Settling Performance
The additive provides reliable thixotropic behavior that resists pigment settling during both storage and application. Effect pigments remain evenly suspended, preventing the re-agglomeration and sedimentation that leads to uneven appearance in the finished coating.

Effective Without Co-Solvent
Anjeka-4561 significantly improves the rheology and brightness of effect pigment slurries even in systems without co-solvent, offering formulation flexibility and supporting lower-VOC recipes.

Application Areas

Anjeka-4561 is recommended for:

• Water-based automotive coatings
• Water-based industrial coatings
• Any water-based system containing effect pigments (metallic, pearlescent, or similar)
• Systems where co-solvent-free formulations are preferred

Recommended Dosage

These are empirical starting guidelines. Optimal dosage varies by effect pigment type, loading level, and performance targets. A series of tests is recommended to determine the best level for your specific formulation.

How to Add

Anjeka-4561 can be incorporated using either of the following methods:

Method 1 — Direct Addition
Add directly to the system without co-solvent or polymer present. The presence of amines in the system helps disperse Anjeka-4561 effectively.

Method 2 — Premix Slurry
Prepare a premix slurry at a ratio of Water : Anjeka-4561 = 4 : 1. Add the premix at any production stage. This method can improve dispersion consistency and is useful when precise incorporation control is needed.

Technical Data

Note: Values shown are typical and do not constitute specification limits.

Storage and Handling

Anjeka-4561 is temperature-sensitive. Storage and transport temperature must be maintained below 45 degrees C. Exposure to temperatures above this threshold may affect product performance and stability.

The product has weak acidity. Handle with standard precautions for mildly acidic chemical materials.

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

Frequently Asked Questions

Q: What does “effect pigment orientation” mean in practice?
Effect pigments — such as aluminum metallics, mica pearlescents, and interference pigments — produce their visual effect by aligning parallel to the coating surface. Uneven or uncontrolled orientation causes visible color variation across the panel (cloudiness, flop variation, or color spots). Anjeka-4561 helps pigment platelets align more uniformly, resulting in consistent brightness and color flop across the entire surface.

Q: How does Anjeka-4561 differ from polyurethane or acrylic thickeners?
While thickeners add viscosity to the entire system, Anjeka-4561 is specifically designed to control effect pigment orientation and settling with less impact on overall system viscosity. This gives formulators more precise rheological control — strong anti-settling and orientation performance without over-thickening the coating.

Q: Can it be used in systems without co-solvent?
Yes. One of Anjeka-4561’s strengths is its ability to improve the rheology and brightness of effect pigment slurries even in co-solvent-free formulations. This supports lower-VOC recipes without sacrificing performance.

Q: What happens if the storage temperature exceeds 45 degrees C?
Anjeka-4561 is temperature-sensitive. Exposure to temperatures above 45 degrees C during storage or transport may cause degradation of performance. Maintain proper cold-chain conditions and monitor storage conditions, especially during summer months or long-distance shipping.

Q: What is the best incorporation method?
Method 1 (direct addition) is simpler and works well in systems with sufficient amine presence. Method 2 (premix slurry at 4:1 water to additive) gives more consistent dispersion and is recommended when maximum uniformity is critical or when the system has low amine content.

Q: Is it suitable for automotive clear coats?
Anjeka-4561 is recommended for water-based automotive basecoats where effect pigments are present. Compatibility with clear coat systems should be verified in your specific formulation, as the clear coat layer typically does not contain effect pigments.

Q: Does the weak acidity of the product require special handling?
The product has weak acidity. Standard chemical handling precautions apply — wear appropriate personal protective equipment when handling, and avoid contact with incompatible materials. Refer to the Safety Data Sheet for full handling guidance.
