The present invention relates to a sealant syringe assembly. An aspect of the present invention may provide a sealant syringe assembly comprising: a first syringe including a plurality of chambers and discharging a first solution which is a mixture of a buffer solution and compound powder； a reaction solution syringe including at least one chamber and discharging a reaction solution capable of reacting with the first solution； a base in which the first syringe and the reaction solution syringe are stably seated； and a connector for connecting the first syringe and the reaction solution syringe to mix and discharge the first solution and the reaction solution, wherein the first solution and the reaction solution react with each other to thus have a changed property such that a shear storage modulus exceeds a shear loss modulus, and the first syringe includes: three packing members provided inside the first syringe； a passage provided in the inner circumferential surface of the first syringe； and a plunger for providing a pressure to one of the packing members, wherein a buffer solution is provided to a chamber of one side provided between the three packing members, and compound powder is a provided to a chamber of the other side provided between the three packing members.
