Viscosity of White Paste in Epoxy 601 Resin System Before and After Hot Storage

Test Method	Store at 60°C for 7 days, measure viscosity change
Test Results	6110S shows good performance in both viscosity reduction and post-thickening control; all other dispersants show significant viscosity increase after hot storage
Performance Rating	6110	6110S	6402	6110A	6915	6916	6976A	6500-50

Gloss of White Paste in Epoxy 601 System Before and After Hot Storage

Test Method	Store at 60°C for 7 days, measure gloss change
Test Results	6976A shows good performance in both 20° and 60° gloss; 6402, 6500-50, and 6916 show good 20° gloss but slightly poorer 60° gloss; 6110 shows slightly poorer 20° gloss but good 60° gloss
Performance Rating	6110	6110S	6402	6110A	6915	6916	6976A	6500-50

L-Value of White Paste in Epoxy 601 Resin System Before and After Hot Storage

Test Method	Store at 60°C for 7 days, measure L-value change
Test Results	6916, 6976A, and 6500-50 show good L-value performance
Performance Rating	6110	6110S	6402	6110A	6915	6916	6976A	6500-50

Dispersant Recommendations for White Paint in Epoxy 601 System

6500-50 — The Best Overall in the 601 System

Viscosity Performance:
Viscosity after 7 days of hot storage is 9,185 mPa·s. Although this value is already high (in the high-viscosity range), it is the only dispersant in this system that maintains a viscosity below 10,000 after hot storage. Compared to other dispersants with viscosities ranging from 20,000 to 40,000, it is the "least bad" choice.

Appearance Performance:
Excellent gloss performance — 60° gloss reaches 123 (the highest gloss record in the entire test), with a very high L-value (93.94), enabling coatings with high distinctness of image (DOI).

Conclusion:
In the 601 system, 6500-50 offers the best overall performance.
