Bentonite for Precision Casting Foundry-Sand Bond
Properties: white powder. It has good plasticity, hydrophily, bonding ability, refractory quality and cation exchange ability. It has high green compression strength and high hot wet tensile strength. It is an ideal molding sand binder for precision casting, which is convenient for casting in wet mold or dry mold. It helps to eliminate the casting sand holes, scab, and sand mold collapse defect.
