BENTONITE POWDER is used as foundry green sand binder for all kind of Compaction (Pressing, Blowing, Vibration etc.) and for all foundry metals and methods of casting and above all get as quick bonding element.
The high Montmorillonite content of BENTONITE POWDER gives always high swelling value with excellent thermal stability. Due to high Montmorillonite values it reduced the additions of Bentonite and can able to maintain Active Clay level.
