具有高亲水性的硅酮印模材料
摘要：
本发明提供具有高亲水性的硅酮印模材料，其在固化前示出即时亲水性，在固化后示出高亲水性，且具有作为齿科用印模材料的优选的特性，保存稳定性优异。在不含硅氧烷聚合物的亲水化材料中与山梨糖醇酐脂肪酸酯系表面活性剂作为亲水化材料并用，在含有硅氧烷聚合物的亲水化材料中与含有聚醚改性硅酮的非离子系表面活性剂作为亲水化材料并用。
摘要（英）：

Provided is a silicone impression material with high hydrophilicity that exhibits instantaneous hydrophilicity before being cured, that exhibits high hydrophilicity after being cured, that has preferable properties for a dental impression material, and that has good preservation stability. A sorbitan fatty acid ester based surfactant and a nonionic surfactant composed of polyester modified silicone are used in combination as a hydrophilizing agent not containing a siloxane polymer and a hydrophilizing agent containing a siloxane polymer, respectively.
