Description

Ferrochromelignosulphonate is a specialized organometallic complex derived from lignosulfonate and chromium, with the CAS registry number 8075-74-9. This compound is valued for its unique combination of chelating, dispersing, and binding properties, making it a critical performance additive in demanding industrial processes. It is primarily sought after by manufacturers in the oil & gas, construction, and metallurgical sectors for its ability to modify rheology and enhance material stability under challenging conditions.

Application

• Oilfield Drilling Fluids: Acts as a high-temperature stabilizer and fluid loss control additive in water-based mud systems.
• Concrete Admixtures: Serves as a water-reducing agent and set retarder to improve workability and strength development in concrete.
• Pelletizing & Briquetting: Used as an efficient organic binder in the agglomeration of iron ore fines, chrome ore, and other metal powders.
• Dispersing Agent: Enhances particle suspension and prevents settling in ceramic slips, pigment slurries, and coal-water mixtures.
• Leather Tanning Auxiliary: Functions as a masking agent and dispersant in chrome tanning processes to improve leather quality and dye uptake.
• Wastewater Treatment: Employed as a coagulant aid and for heavy metal sequestration in industrial effluent treatment.
• Agricultural Formulations: Used as a chelating agent in micronutrient fertilizers and as a binder for pesticide granules.

Quality Control

Our Ferrochromelignosulphonate is manufactured under a stringent quality management system. Each batch undergoes rigorous testing for key parameters including active content, chromium and iron concentration, pH, solubility, and performance in standard application tests. Certificates of Analysis (COA) documenting these specifications are available upon request to ensure compliance with your process requirements.

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); the original container must be kept tightly sealed after use to prevent caking and degradation due to moisture absorption.
