摘要
An embedding material composition for casting The present invention provides an embedding material composition for casting that makes it possible to achieve a favorable casting in the case of a resin pattern that is different from a conventional wax pattern in evaporative temperature and evaporative behaviors through ＂rapid heating＂ - excellent in treatment efficiency. The main components of the casting embedding material compnses a Under and a non-heat-expandable refractory material having an average particle diameter of 5 to 20 pro.
