Abstract: A sand core is prepared for use in defining a surface of a cast metal article. The core is formed of sand particles bonded with a polyurethane resin, preferably a polyol moiety-containing polyurethane resin. An alkali metal hydroxide, and optionally a glycol, is mixed with precursors of the polyurethane before they are mixed with sand particles for molding and curing the core. The hydroxide and glycol may be encapsulated to prevent interference with core molding.
