Bentonite Applications: Molding Sand Binder: In the foundry industry, bentonite is used as a binder for molding sand, which can overcome phenomena such as "sand inclusion" and "skin formation" in castings, thereby reducing the scrap rate of castings and improving their precision and finish.

Bentonite boasts excellent properties such as expandability, suspension, adhesiveness, and lubricity. When added to joint compound (paste), it ensures the compound remains moisture-free for extended storage, applies smoothly to walls with flexibility and luster, maintains even thickness, and exhibits excellent adhesion. It combines well with both wall surfaces and overcoat latex paints. As a non-radiative green mineral product, it is ideal for joint compound manufacturers.

Market bentonites for putty (paste) come in calcium-based, sodium-based, white, and mixed colors, with varying grades (effective components). Applications show that calcium-based bentonite significantly differs from sodium-based in terms of water retention, adhesion, and lubricity. Our putty bentonite, however, is enhanced to meet all the necessary specifications for putty, fully leveraging its performance for ease of use, cost-effectiveness, and to meet market demands.
