<p><P>PROBLEM TO BE SOLVED: To provide a release agent composition causing no quality defect in a low-speed casting method to solve such a problem that, though casting defects are relatively hard to be cused in the conventional release agent because of its satisfactory thermal conductivity and is suitable as a small-sized component with a simple shape, in the case of a large-sized component with a complicated shape or a thin component, quality defects caused by a miss run are easy to be generated, and to. <P>SOLUTION: The release agent for mold casting is prepared by suspending release agent particles, which is composed of a metal salt compound having an Mohs hardness of 3 to 4, into the water containing a dispersant. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
