Title: ADHESIVE COMPOSITION, METHOD FOR PRODUCING ADHESIVE COMPOSITION, BONDING METHOD USING ADHESIVE COMPOSITION, AND STRUCTURE HAVING ADHESIVE COMPOSITION ATTACHED THERETO
Abstract:
[Problem] To provide an adhesive composition which is based on naturally derived raw materials that do not have an adverse effect on the human body and which has a tensile shear strength (adhesive strength) of 1 MPa or more for a variety of adhered objects. [Solution] Provided is an adhesive composition that contains at least a first agent and a second agent, wherein the first agent contains a tannic acid derivative in which hydrogen atoms in at least some of the hydroxyl groups in tannic acid are substituted with a linear hydrocarbon group having at least one hydroxyl group, and the second agent contains a hydrocarbon having at least two cyanate groups or a derivative of the hydrocarbon.
