Dispersant Recommendations for White Paint in Epoxy 828 System

6976A — The First Choice for Extreme Viscosity Reduction & High L-Value

Core Advantage: Extreme viscosity reduction and high L-value.

Viscosity Control:
After 7 days of hot storage, its viscosity not only did not increase but actually decreased — making it one of the lowest-viscosity dispersants after hot storage among all tested.

Appearance Performance:
Achieves the highest L-value in the system, though its gloss is slightly lower.

Conclusion:
If you pursue the best application flowability (low viscosity) and final coating appearance, 6976A is the absolute first choice
