Description

Lignosulfonic Acid, Magnesium Salt is a water-soluble, anionic polyelectrolyte derived from the sulfite pulping process of wood. This versatile compound serves as a highly effective dispersant, binder, and stabilizer across numerous industrial applications. It is particularly valued in the construction, agriculture, and ceramics industries for its ability to control rheology, reduce dust, and improve product performance. Global manufacturers rely on its consistent quality and multifunctional properties to enhance their formulations and processes.

Application

• Concrete Admixture: Acts as a water-reducing agent and plasticizer to improve workability and strength of concrete mixes.
• Ceramics & Refractories: Functions as a binder and deflocculant in clay bodies and castable refractories, improving green strength and moldability.
• Agricultural Formulations: Used as a dispersing agent and tackifier in pesticide and fertilizer suspensions and granules.
• Oil Well Drilling Fluids: Serves as a thinner and fluid loss control additive in water-based mud systems.
• Dye & Pigment Dispersant: Enhances the stability and color development of dye and pigment slurries.
• Dust Control Agent: Applied to roads and mining sites to suppress airborne dust particles.
• Industrial Pelletizing: Used as a binder in the agglomeration of fine powders, such as iron ore or coal dust.
• Textile Printing: Employed as a thickening agent and dye leveler in textile printing pastes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking. Keep away from strong oxidizing agents.
