Abstract
A two-part curable adhesive composition includes a main agent (A) containing a urethane prepolymer (a1) and a remaining polyisocyanate (a2), and a curing agent (B) containing a non-crystalline polyol compound (b1) and a polyamine compound (b2). An equivalent ratio of an isocyanate group in a raw polyisocyanate to a hydroxyl group in the polyol compound is from 2.05 to 12. The equivalent ratio of the isocyanate group in the main agent (A) to an amino group in the polyamine compound (b2) is from 1.2 to 6. The equivalent ratio of the isocyanate group in the main agent (A) to the hydroxyl group in the non-crystalline polyol compound (b1) is from 2 to 12.
