Zusammenfassung:A coating agent composition for casting according to the present invention contains: a polymer A having, as a skeleton, a constituent unit a induced by polymerizing at least one selected from the group consisting of (meth) acrylic acid, (meth) acrylic acid ester, and (meth) acrylamide; and a constituent unit b induced by polymerizing at least one selected from the group consisting of a (meth) acrylic acid having polyoxyalkylene chains, a (meth) acrylic acid ester having polyoxyalkylene chains, and a (meth) acrylamide having polyoxyalkyilene chains; a solvent; and fire-resistant particles. Thecoating agent composition for casting according to the present invention can provide a coating agent composition for casting having a good coating workability onto mold surfaces and a good re-dispersion property of fire-resistant particles. 本发明的铸造用涂模剂组合物含有聚合物A、溶剂和耐火性粒子,所述聚合物A具有结构单元a和结构单元b作为骨架,所述结构单元a是通过将选自(甲基)丙烯酸、(甲基)丙烯酸酯和(甲基)丙烯酰胺中的1种以上进行聚合而衍生的结构单元,所述结构单元b是通过将选自具有聚氧亚烷基链的(甲基)丙烯酸、具有聚氧亚烷基链的(甲基)丙烯酸酯和具有聚氧亚烷基链的(甲基)丙烯酰胺中的1种以上进行聚
