Product Description
Bentonite Powder is a highly absorbent, natural clay primarily composed of montmorillonite. It features strong swelling properties and excellent colloidal qualities. Bentonite Powder appears as a grey to pale cream powder with a high capacity for water absorption, forming a gel-like substance when mixed with water. This makes it invaluable for drilling muds, foundry binders, sealing ponds or wells, and water treatment applications. Zenco Chemicals supplies premium quality Bentonite Powder across Kenya, Uganda, Tanzania, Rwanda, and the wider East African region with reliable delivery and competitive pricing.
