Description

Lignosulfonic Acid, Aluminum Salt is a water-soluble polyelectrolyte derived from lignin, a major component of wood. This compound is valued for its ability to function as a versatile dispersant, binder, and stabilizer in a wide range of industrial formulations. It is particularly essential for manufacturers in sectors such as construction, agriculture, and ceramics who require effective and economical additives to control rheology and particle suspension.

Application

• Concrete Admixtures: Acts as a water-reducing agent and plasticizer to improve workability and strength of concrete mixes.
• Ceramic & Refractory Binders: Serves as an effective temporary binder for shaping ceramic bodies and refractory materials before firing.
• Agricultural Dispersants: Used in pesticide and fertilizer formulations to enhance the dispersion and stability of active ingredients.
• Oil Well Drilling Fluids: Functions as a deflocculant and thinner to control the viscosity and fluid loss of drilling muds.
• Dye & Pigment Dispersant: Improves the dispersion and color strength of dyes and pigments in various liquid systems.
• Industrial Detergents: Enhances the cleaning power and soil suspension properties in heavy-duty cleaning formulations.
• Pelletizing & Briquetting Aid: Used as a binding agent in the agglomeration of fine powders like coal dust, minerals, and animal feed.
• Foundry Sand Binder: Acts as a core binder in metal casting processes to provide green strength to sand molds.

Quality Control

Our Lignosulfonic Acid, Aluminum Salt is produced under strict quality management protocols to ensure batch-to-batch consistency and performance reliability. While typically supplied as an industrial-grade material, production can be aligned with specific customer requirements. A comprehensive Certificate of Analysis (COA) detailing parameters such as solids content, pH, sulfonate content, and ash content is provided with each shipment to guarantee specification compliance.

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 material is hygroscopic (moisture-sensitive); ensure containers are kept sealed when not in use to prevent caking or absorption of atmospheric moisture. Keep away from strong oxidizing agents.
