  • Applications

    Calcium lignosulfonate, CAS number 8061-52-7, is widely used as a water-reducing agent and set-retarder in cementitious admixtures, improving workability and performance of concrete. It also serves as a binder in iron ore pelletization and may be used for other mineral pellets. In coatings, paints, and inks it acts as a pigment dispersant and formulation aid. It is used as a dust suppressant and humectant for soil and unpaved roads, helping reduce dust and stabilize surfaces. In agriculture, it can function as a binder and carrier for fertilizer granules and agricultural formulations. It may also serve as a dispersant in cleaning formulations and industrial detergents.
