6916 — The First Choice for Extreme Viscosity Reduction & High Gloss

Core Advantage: Extreme viscosity reduction and high gloss.

Viscosity Control:
After 7 days of hot storage, the viscosity did not increase but actually decreased to 1,328 mPa·s (initial viscosity: 3,237 mPa·s) — the lowest viscosity after hot storage among all dispersants tested.

Appearance Performance:
Achieves the highest 20° gloss (98.2) and L-value (93.84) in the system.

Conclusion:
If you pursue the best application flowability (low viscosity) and final film appearance (high gloss, high distinctness of image), 6916 is the absolute first choice.

6915 & 6500-50 — Excellent and Stable Backup Options

These two dispersants deliver excellent and stable performance, making them reliable backup choices.

Common Features:

Parameter Performance
Viscosity Control Viscosity after hot storage stabilizes at approximately 1,881 mPa·s — not as extreme as 6916, but far better than other dispersants
Appearance Performance L-value remains above 93.7, with excellent gloss (108–110) as well

Conclusion:
Performance is second only to 6916, suitable for applications with high requirements for gloss and leveling.
