This investigation evaluated the effect of unfilled resins and a silane primer on bonding between layers of a urethane-based composite resin veneering material. Shear bond strengths between the layers were determined with a two-liquid silane primer and three unfilled resin bonding agents. The silane primers and unfilled resins enhanced the bond between layers of the veneering material. Durability of the bond, however, was influenced by the composition of the bonding agent. Among the systems investigated, combined use of the silane primer with triethyleneglycol dimethacrylate-based unfilled resin exhibited durable and consistent bond strength.
本研究评估了未填充树脂和硅烷底漆对聚氨酯基复合树脂贴面材料各层之间粘结的影响。使用双液型硅烷底漆和三种未填充树脂粘结剂测定各层之间的剪切粘结强度。硅烷底漆和未填充树脂增强了贴面材料各层之间的粘结。然而，粘结的耐久性受粘结剂组成的影响。在所研究的体系中，硅烷底漆与三乙二醇二甲基丙烯酸酯基未填充树脂联合使用表现出持久且一致的粘结强度。
