Description

Egyptianmontmorillonite CAS NO 61029-13-8 is a naturally occurring, high-quality clay mineral belonging to the smectite group, prized for its exceptional colloidal and adsorptive properties. This material is a critical industrial raw material, valued for its ability to swell, form gels, and exchange ions, which makes it indispensable in a wide range of manufacturing and processing applications. Key industries that rely on this versatile clay include drilling, construction, agriculture, and environmental remediation, where it serves as a vital rheological modifier, binder, and absorbent.

Application

• Drilling Fluids: Primary application as a viscosifier and fluid loss control agent in water-based drilling muds for oil, gas, and geothermal wells.
• Foundry & Construction: Used as a bonding agent in foundry sands for metal casting and as an additive in cement, mortars, and plasters to improve workability and water retention.
• Agriculture & Animal Feed: Acts as a pelletizing binder for animal feed and a soil conditioner to improve moisture retention and nutrient delivery.
• Environmental Remediation: Employed as a low-cost, effective absorbent for heavy metals and organic contaminants in wastewater treatment and spill control.
• Pharmaceuticals & Cosmetics: Utilized as an excipient, suspending agent, or rheology modifier in topical formulations, creams, and medicinal clays.
• Catalyst & Carrier: Serves as a catalyst support or carrier in various chemical synthesis and petrochemical refining processes due to its high surface area.
• Paper & Paints: Functions as a filler, coating pigment, and rheology control agent in paper manufacturing and paint formulations.
• Desiccant & Sealant: Used in its activated form as a desiccant and in sealing applications for ponds, landfills, and containment barriers.

Quality Control

Our Egyptianmontmorillonite is sourced and processed under strict quality protocols to ensure batch-to-batch consistency and performance. We adhere to relevant industry standards, including API 13A specifications for drilling-grade material and FCC guidelines for food-contact applications where applicable. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, detailing key parameters such as viscosity, swelling index, and chemical composition.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at ambient temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in its original, sealed packaging until use to prevent caking and performance degradation. Keep away from incompatible materials.
