Description

Lignosulfonicacid,Calciumsodiumsalt CAS NO 37325-33-0 is a water-soluble polyelectrolyte derived from lignin, a major component of wood. This versatile biopolymer is valued for its excellent dispersing, binding, and complexing properties, making it a key sustainable additive in numerous industrial processes. It is primarily needed by manufacturers in the construction, agriculture, and chemical processing industries seeking effective and environmentally friendly performance materials.

Application

• Concrete Admixture: Acts as a highly effective water reducer and plasticizer, improving workability and strength of concrete mixes.
• Dust Control Agent: Used for soil stabilization and dust suppression on roads and construction sites.
• Agricultural Dispersant: Enhances the suspension and efficacy of pesticides, herbicides, and liquid fertilizers.
• Ceramic & Binder Industry: Serves as a binder and deflocculant in ceramic bodies and clay formulations.
• Oil Well Drilling Mud: Functions as a thinner and fluid loss control additive in drilling fluids.
• Dye & Pigment Dispersant: Improves the dispersion and stability of dyes and pigments in various formulations.
• Pellet Binder: Used as an organic binder in the production of animal feed pellets and mineral briquettes.
• Industrial Dispersant: Applied in ore flotation, coal-water slurries, and other processes requiring particle dispersion.

Quality Control

Our Lignosulfonicacid,Calciumsodiumsalt is produced under strict quality management protocols to ensure batch-to-batch consistency and performance reliability. While specifications vary by grade (e.g., industrial, construction, agricultural), our products undergo rigorous testing for key parameters such as purity, sulfonate content, pH, and solubility. Certificates of Analysis (COA) are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent caking and absorption of atmospheric moisture.
