Description Calcium lignosulfonate is a multi-component high molecular polymer anionic surfactant, the appearance is light yellow to dark brown powder, slightly aromatic odor, the molecular weight is generally between 800 and 10000, with strong dispersibility, Adhesion and chelation. It is usually spray-dried from cooking waste liquor from acid pulping (or sulfite pulping).

Application Application
Granulating agent for limestone and ores, compaction aid for coal and metal wastes, and dispersing agent for gypsum and clay slurries.

Features And Benefits Compatible with anionic and nonionic dispersants and wetting agents.
