Sodium Lignosulphonate (MN-1)

An anionic surfactant and natural polymer, na lignosulphonate. ideal for dispersing particles in aqueous medium; strong dispersing capacity. They can perform metal ion exchange because of the difference in their molecular weight and functional groups, and since they contain a variety of active groups in their structure, they can produce condensation or hydrogen bonds with other substances. They can also be adsorbed on the surface of different solid particles.
