In metal casting, bentonite is used together with carbonaceous materials as an inorganic bonding material in green sand moulding. For this application, we supply a full range of top quality and high performing bentonite-based products to meet our customer needs. All our products have a high montmorillonite content, offer high thermal stability, excellent bonding power, and consistent quality. Further, we wish to point out that with our bentonite, no toxic emissions are released during mould making and casting.
