Description

Muscovite, Mixt. With Kaolin is a naturally occurring industrial mineral blend composed of muscovite mica and kaolin clay. This synergistic combination offers a unique profile of chemical inertness, thermal stability, and reinforcing properties, making it a valuable functional additive. It is primarily utilized in sectors requiring enhanced material performance, such as polymer composites, paints and coatings, and construction materials. The product is supplied under the CAS registry number 58799-47-6.

Application

• Polymer & Rubber Composites: Acts as a reinforcing filler and property modifier to improve dimensional stability, heat resistance, and mechanical strength in plastics, elastomers, and masterbatches.
• Paints, Coatings & Inks: Functions as an extender pigment and flatting agent to enhance durability, weather resistance, and control gloss in industrial and decorative formulations.
• Construction Materials: Used in cement, joint compounds, and sealants to improve workability, reduce cracking, and enhance water resistance.
• Ceramics & Refractories: Serves as a raw material contributing to thermal shock resistance and structural integrity in high-temperature applications.
• Paper & Packaging: Employed as a coating pigment to improve printability, smoothness, and opacity of paper products.
• Adhesives & Sealants: Provides thickening, reinforcement, and barrier properties to enhance performance and application characteristics.
