Abstract
534,323. Mould materials. EASTERN CLAY PRODUCTS, Inc. Jan. 26, 1940, No. 1642. Convention date, Feb. 3, 1939. [Class 83 (i)] In making sand moulds non-swelling, colloidal montmorillonite clay is used as the binder. This clay is sometimes referred to as non-swelling colloidal bentonitic clay, sub-bentonite, or acid bentonite. From ¢ to 8 per cent. of the clay may be used and the sand may contain some sand from old moulds. Auxiliary binders in small quantities, e.g. cereal binders, cement, goulac, pitch or rosin, and casting cleaning elements such as sea coal, wood flour or oils may also be added. This binder is stated to give moulds having a greater green compression strength and permeability than either swelling, colloidal montmorillonite or non-swelling, non- colloidal montmorillonite.
