PROBLEM TO BE SOLVED: To obtain a releasing agent excellent in mold adhesivity and heat resistance by dispersing powder selected from mica, molybdenum disulfide, graphite and the like, and a silica sol. SOLUTION: This releasing agent is obtained by dispersing (A) powder selected from mica, molybdenum disulfide, graphite, talc, celite, graphite fluoride, silicon powder and boron nitride and (B) a silica sol. In the above releasing agent, the weight ratio (component A/SiO2 ) of the component A to the component B in terms of SiO2 is preferably 0.1-50. The releasing agent is obtained, for example, by dispersing and mixing the component A and a dispersant such as ethanol into a homogeneous state, and subsequently adding an alkoxy silane such as tetraethoxysilane to the obtained mixture and mixing them by stirring. |
