Engineered for Binding and Rheology
Bentonite is a highly colloidal aluminum silicate clay, primarily composed of the mineral montmorillonite. Characterized by its exceptional hydration, swelling, and absorption properties, it undergoes strict quality processing to optimize its ion-exchange capacity. This process alters its structural performance, maximizing its binding strength, viscosity-building capabilities, and thermal stability.
Key Features
- High Swelling & Hydration Capacity: Sodium bentonite can absorb several times its dry weight in water, expanding into a highly viscous, gel-like suspension.
- Superior Binding Strength: Provides excellent green and dry compressive strength, making it an indispensable bonding agent.
- Excellent Rheological Properties: Exhibits strong thixotropic behavior, acting as a highly efficient suspending and anti-settling agent in liquid formulations.
- Thermal Stability: Maintains its structural integrity and binding properties under extreme high-temperature conditions.
