PROBLEM TO BE SOLVED: To provide rapidly-curing on-demand adhesive systems that has a non-thermal trigger, and that are delivered in a form awaiting triggering at a later time by applying ultrasonic (US) energy.SOLUTION: A method for making an adhesive comprises the steps of: mixing a resin-based compound with an encapsulated catalyst to form an uncured resin-based adhesive; directing ultrasonic energy from an ultrasonic energy source to the uncured resin-based adhesive; rupturing the catalyst; and curing the uncured resin-based adhesive. Also provided is a rapidly-curing adhesive in which the resin-based compound comprises an epoxy resin-based compound, and the encapsulated catalyst comprises an amine-based compound.SELECTED DRAWING: None 【課題】非熱的誘発を有し、超音波（ＵＳ）エネルギーを加えることによって、後になって誘発を待つ形態で実現される急速硬化のオンデマンド接着剤システムの提供。【解決手段】未硬化樹脂系接着剤を形成するために樹脂系化合物をカプセル化触媒と混合するステップと；超音波エネルギー源からの超音波エネルギーを前記未硬化樹脂系接着剤に方向付けるステップと；前記触媒を破損させるステップと；前記未硬化樹脂系接着剤を硬化させるステップとを含む、接着剤を作るための方法。前記樹脂系化合物はエポキシ系樹脂化合物を含み、前記カプセル化触媒はアミン系化合物を含む、急速硬化接着剤。【選択図】なし
