Title:
TWO-PART CURABLE ADHESIVE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2020/067527
Kind Code:
A1
Abstract:
This two-part curable adhesive composition comprises: a main agent (A) containing a urethane prepolymer (a1) and a residual polyisocyanate (a2); and a curing agent (B) comprising an amorphous polyol compound (b1) and a polyamine compound (b2). The equivalent ratio of isocyanate groups within a raw material polyisocyanate to hydroxyl groups within the polyol compound is 2.05−12. The equivalent ratio of isocyanate groups within the main agent (A) to amine groups within the polyamine compound (b2) is 1.2−6. The equivalent ratio of isocyanate groups within the main agent (A) to hydroxyl groups within the amorphous polyol compound (b1) is 2−12.
