Bentonite Applications: Mold Sand Binder: In the foundry industry, bentonite is used as a mold sand binder, which can overcome issues such as "sand inclusion" and "peeling" in castings, thereby reducing the scrap rate of castings and improving their accuracy and finish.

Bentonite has excellent properties such as expansion, suspension, adhesion, and lubricity. Added to putty powder (paste), it ensures the putty paste remains moisture-free for extended periods, provides flexibility and sheen when applied to walls, maintains even thickness, and exhibits excellent bonding capabilities, whether with the wall or over topcoat latex paint. It is a non-radiative green mineral product, ideal for putty manufacturers.

Market-grade bentonites used for putty powder (paste) come in calcium-based, sodium-based, white, and mixed colors, with varying grades (effective ingredients). Applications show that calcium-based bentonite is significantly different from sodium-based in terms of water retention, adhesion, and lubricity. Our produced putty powder bentonite is designed to enhance the required specifications for putty powder, fully leveraging its properties to ensure its ease of use, cost-effectiveness, and ability to meet market demand.
