RedCast^® and BlackCast^® are proven anti-veining agents for foundry castings. RedCast, used in core sand and no-bake molds, eliminates or greatly reduces nitrogen gas defects and reduces expansion defects in low sand to metal ratio casting. It is used in cast iron, nodular iron, and steel foundry applications. BlackCast, also used in core sand and no-bake molds, eliminates or greatly reduces veining for cast iron, nodular iron, and steel foundry applications.
