Anjeka 6072 Advantages in Viscosity Reduction, Water Resistance, and Color Development in Waterborne Epoxy/Alkyd System

The shift towards waterborne industrial coatings brings challenges in viscosity control, water resistance, color development, and gloss stability. Anjeka 6072, a high molecular weight block copolymer dispersant, acts as a versatile solution for formulators.

Key Formulation Problems Solved

1. High Viscosity & Poor Flow: Effectively reduces system viscosity in high-PVC or resin-free paste formulations, improving processability.
2. Inadequate Water Resistance: Provides excellent resistance to blistering and adhesion loss after water immersion, crucial for long-term protection.
3. Poor Color Development & Stability: Ensures consistent color strength, reduces flooding/floating, and enhances storage stability of tinting pastes.
4. Difficulty in Achieving Matte Effect: Efficiently disperses matting agents, enabling high matting efficiency and good anti-settling.
5. Poor Storage Stability: Minimizes viscosity increase, settling, and re-agglomeration during storage.

Performance Advantages & Characteristics (Based on Test Data)

1. Outstanding Viscosity Reduction & Dispersion Power

• Data: In resin-free black paste, viscosity with Anjeka 6072 (200 mPa.s) is significantly lower than with CYTEC 6208 (400 mPa.s) and Sanzhan 578 (250 mPa.s). Similar advantages are seen in white paste.

2. Excellent Water Resistance

• Data: After 7-day water immersion, Anjeka 6072 performs similarly to CYTEC 6208 and better than Sanzhan 578 in epoxy emulsion and PUD systems (blistering area 10%-20%, adhesion loss <1%). Comparable performance is observed in waterborne alkyd systems.

3. Minimal Impact on Gloss & Superior Color Development

• Data: In waterborne epoxy white paint, 6072 achieves a high 60° gloss of 85.5 (rated 8/8). Remarkably, in waterborne epoxy black paint, it delivers a gloss of 67.4 (rated 8/8), indicating excellent transparency and jetness, outperforming most competitors[6]. It also receives high ratings for color development across multiple shades.

4. Effective Matting Agent Dispersion

• Data: 6072 drastically reduces the viscosity of matting agent pastes (from >20,000 to below 510 mPa.s) and achieves a matting efficiency up to 99.0% with good anti-settling properties.

5. Broad System Compatibility

• Anjeka 6072 demonstrates good performance in various resin systems including waterborne epoxy, alkyd, styrene-acrylic emulsion, and PUD, making it suitable for universal paste preparation.

Application Recommendations

• Universal Paste: Ideal for preparing resin-free universal pastes, especially for epoxy and PU systems demanding high water resistance and color strength.
• Matte Coatings: Recommended for dispersing matting agents to achieve low viscosity, high matting efficiency, and stability.
• Performance Troubleshooting: Consider 6072 when facing issues with high viscosity, poor water resistance, or color instability.
