Contact SupplierWe are offering foundry grade bentonite. As bentonite clay is used as binding substance to metal manufacture molding and core sand mixtures, as well as non-stick coating in the field of foundry. This area is one of the priorities to our organization. Our foundry grade has a high montmorillonite & high swelling content and is a sodium bentonite suitable for sand applications including fully automated and high-pressure systems.
Our foundry grade material provide these benefits.
• quick bond development - higher milling capacity
• moisture resistivity - sand control and consistent quality
• mouldability - great mould integrity
• high swelling - resistance in expansion
• thermal stability – good casting quality
