Fine powder lignosulfonate dispersant for pigments, fillers, carbon black, ceramics and industrial suspensions.
Calcium Lignosulfonate Dispersant Grade Powder is a fine brown powder dispersant for insoluble pigments, fillers, carbon black and aqueous suspension systems.
It is designed to facilitate dispersion, re-dispersion and long-term suspension stability in industrial formulations such as coatings, ceramics, concrete admixtures and drilling fluids.
This grade is especially useful where customers need better solids distribution, lower settling and more stable processing behavior.
Key Performance Functions
High-Efficiency Dispersion
Assists dispersion of insoluble pigments, fillers and carbon black.
Re-Dispersion Support
Facilitates easier re-dispersion during storage or use.
Suspension Stability
Improves long-term stability and reduces settling.
Electrostatic Stabilization
Strong anionic groups support particle repulsion in water-based systems.
