Core Advantage:
Rheological performance is nearly perfect. Not only is the initial viscosity extremely low, but after 7 days of hot storage, the viscosity decreases instead of increasing — making it the dispersant with the lowest viscosity after hot storage among all tested.
Overall Performance:
In addition to excellent viscosity reduction, its gloss (20°/60°) and L-value are also among the best in the system. All performance indicators are well balanced.
Core Advantage:
Best-in-class gloss performance. After 7 days of hot storage, its 60° gloss reaches 109.1, and its L-value reaches 93.66 — outstanding appearance performance.
Main Disadvantage:
Higher viscosity. Although the initial viscosity is acceptable, it increases significantly after hot storage.
