Abstract
The invention relates to improvements of RCS and casting molds therefrom. The improvement resides that the resinous coating contains halogen-containing compound(s) which accelerate(s) carburizing of the resin during under heat subjected to the molten metal pouring step. Further, the resin coating comprises certain amount of pulverized metal capable of reacting under heat with separated halogen or halogen compound during the casting step and for avoiding ferrous element(s) in the castings and/or the mold(s).
