4 Claims

1. An adhesive agent set comprising a main agent and a hardening agent,

wherein the main agent contains a urethane prepolymer having isocyanate groups as terminal groups; and an oligomer of hexamethylene diisocyanate having an isocyanate group modified with a silane coupling agent having a mercapto group, the oligomer also having at least two unmodified isocyanate groups,

wherein the hardening agent contains a polyol,

wherein the content of the urethane prepolymer is 30% to 40% by mass based on the total amount of the main agent, and

wherein the content of the oligomer is 3% to 6% by mass based on the total amount of the main agent.
