Description

Lignosulfonic Acid, Calcium/Magnesium Salt is a water-soluble, anionic polyelectrolyte derived from the sulfite pulping process of wood. This versatile biopolymer is valued for its excellent dispersing, binding, and complexing properties, making it a key component in various industrial formulations. It is primarily utilized in sectors such as construction, agriculture, and chemical manufacturing where effective and sustainable material performance is required.

Application

• Concrete Admixtures: Acts as a highly effective water-reducing agent and plasticizer to improve workability and strength of concrete mixes.
• Agricultural Dispersants: Used in pesticide and fertilizer formulations to enhance the dispersion and stability of active ingredients.
• Ceramic & Brick Manufacturing: Serves as a binder and plasticizer in clay bodies to improve green strength and forming characteristics.
• Oil Well Drilling Fluids: Functions as a thinner and dispersant to control rheology and fluid loss in drilling muds.
• Dye & Pigment Dispersions: Improves the stability and color uniformity of dispersions in textile and paint industries.
• Dust Control: Applied as a binder for dust suppression on roads and mining sites.
• Animal Feed Pellet Binder: Enhances the durability and quality of feed pellets.
• Lead-Acid Battery Expander: Used in negative plates to improve battery performance and cycle life.
