Bentonite is used as a bonding material in the preparation of molding sand for the production of iron, steel and non-ferrous casting. The unique properties of bentonite yield green sand moulds with good flowability, compactability and thermal stability for the production of high quality castings.

Our Foundry Grade Bentonite Powder is used as a bonding material in the preparation of molding sand for the production of iron, steel and non-ferrous casting. Sodium Bentonite is the preferred binding agent for use in bonding of metals and foundry sands, although calcium Bentonite enhances foundry sand's flow ability and figures in the manufacture of nonferrous moldings. Foundries also employ sodium Bentonite to clean impurities from melted metals before pouring them.
