American Colloid Company is one of the world’s leading producers of bentonite clay. Bentonite’s unique chemical structure gives it a diverse range of capabilities, enabling it to act as a thickener, sealant, binder, lubricant or absorbtion agent. The Company’s principle markets include metalcasting, pet products, oil and gas well drilling, industrial specialties and agriculture. With mining operations throughout North America and a sister subsidiary with mining operations throughout the world, American Colloid’s trademark Additrol line is an industry standard in the metalcasting industry. Ferro-alloy bricks and briquettes are also part of the Metalcasting Products Group’s product line. American Colloid’s Premium Gel is ideal for multiple applications in oil well drilling. The Company’s Pet Products Group also offers a complete line of traditional, scoopable and alternative cat litters.

American Colloid Company places an emphasis on quality, excellence and accuracy in processing technology. This and our unmatched mineral reserves have enabled us to become the world's largest producer of smectite clays, specifically, sodium and calcium montmorillonites (bentonites), hectorites and magnesium aluminum silicates.American Colloid Company’s Industrial Specialties Group mines and processes smectite clay, both hydro classified and dry processed, for use in Ceramics, Paints & Coatings, Wine and Juice clarification, Printing inks, Rubber, Asphalt, and specialty household and consumer applications.The most common members of the smectite mineral group are hectorite and montmorillonite. The clay’s products are useful in gelling, binding, thickening, stabilizing, plasticizing, coagulating, emulsifying, absorbing and controlling rheology.Our bentonites and hectorites are used widely in a variety of specialty industrial and consumer formulations. The clays increase viscosity, stabilize emulsions, modify the consistency and feel of products and improve spreadability. These clay products are also excellent suspending and dispersing agents. The clays change the rheological properties of the formulations, provide a smoother texture and offer good application properties due to their thixotropic characteristics.
