PROBLEM TO BE SOLVED: To provide a silicone impression material with high hydrophilicity, which exhibits instantaneous hydrophilicity before being cured, exhibits high hydrophilicity after cured, and has preferable properties as a dental impression material and excellent preservation stability.SOLUTION: A sorbitan fatty acid ester-based surfactant as a hydrophilizing material not containing siloxane polymer and a nonionic surfactant comprising polyether-modified silicone as a hydrophilizing material containing a siloxane polymer, are used in combination as the hydrophilizing material, respectively. |
