Abstract
The two-part curable adhesive composition contains a main agent (A) containing a urethane prepolymer (a1) and a residual polyisocyanate (a2), and a curing agent (B) containing a polyol compound (b1) and a polyamine compound (b2). The urethane prepolymer (a1) is made by reacting in an equivalent ratio of an isocyanate group in a raw material polyisocyanate to a hydroxy group in a polytetramethylene ether glycol being 2.05 or greater. The equivalent ratio of an isocyanate group in the main agent (A) to an active hydrogen group in the curing agent (B) is from 0.5 to 4.
