Dispersant Recommendations for White Paint in Hydroxy Acrylic System
6402 — The "All-Rounder" in the 965 System

Core Advantage:
Best gloss performance. Low initial viscosity, with only a slight increase after 7 days of hot storage; good L-value performance as well.

Overall Performance:
Its gloss (20°/60°), viscosity, and L-value are all among the top performers in the system, with well-balanced and excellent indicators. This dispersant delivers outstanding and stable performance, making it a reliable choice.

6500-50

Viscosity Control:
Viscosity remains stable at approximately 1881 mPa·s after hot storage, ranking among the top performers.

Appearance Performance:
Excellent L-value and gloss performance.

Conclusion:
Overall performance is second only to 6402, making it suitable for applications with high L-value requirements.
